HMS Atalanta 1775 by tlevine - FINISHED - 1:48 scale - from TFFM plans


Recommended Posts

Author:  Dan Vad  I started out doing that (chocking) to both sides before I realized that the port side wasn’t going to be seen anyway (planked over).  I then used scarf joints instead of chocks for that side – MUCH quicker, neater and easier.  Greg used ONLY scarf joints on his Pegasus – at the end of the day the chocks will be virtually invisible if you plan on adding any decks, etc.


Author:  remcohe.   All the frames on my build have scarf joints.  I made scores with a scalpel to simulate the chocks.  But the fairing made them disappear…  I guess I don’t miss them on the inside, maybe I’ll add them again on the outside if I feel it looks better.  Remco

 

December 5, 2011.  I actually completed my first full frame.  I decided to roughly sand down the counter filling timbers.  This was done with the drum sander on the Dremel.  Of course, as I was doing this the entire starboard assembly came off in my hand.  The good news was that I had an easier time taking off the excess wood off the model and it also gave me better access to the port side.  Except for installing the sills for the ports, Chapter 2 is now completed!

I had previously made up the knee of the head.  I drilled the bobstay holes and the gammoning hole and cleaned them up with Swiss files.  The lacing piece abuts the stem below water and this joint has a flannel lining.  The more superior joints are above water and have no flannel.  The lacing piece had to be trimmed the thickness of the flannel so that the assembly would lie flush against the stem.  The knee of the head tapers from top to bottom and fore to aft.  The narrowest part is scale 4” wide and at the stem it is scale 10” wide.  I used pencil to highlight the edges of the various pieces.

Dec. 5, 2011.  On to the full frames!  Each of the timbers is a narrower width as you go from keel to toptimber.  The lowest timber (the floor) is 10”, the next futtock is 9.5” and the toptimber is 9”.  That translates into real measurements of 0.108”, 0.098” and 0.088”.  It does not sound like much but it is a noticeable difference, as can be seen in the photos.  I have decided to put the flat part of the frame aft and the stairstep fore unless I can see an offset on the plans.  The framing plan (Disposition Plan) is actually for Cygnet, one of the other Swan sloops.

Author:  Dan Vad.  One thing I would have done with the benefit of my 20/20 hindsight is to fit the fillings at the same time as each square frame.  Cutting them (to the shape of the larger one in a pair) would be easier, they can be faired along with the frames saving double work, they’ll strengthen the whole framework immensely and they will space the bottoms of the frames and avoid the problem I had with the keel (twisting).  Be aware that not all the spacings at the bottoms of the frames are the same – there’s quite a bit of variation which can be taken from the Disposition plan.  Gluing the filling to the frame to be fitted and finessing it to thickness before gluing the frame in would be the way to go.

 

Author:  druxey.  The only caution to take if fitting the fillers as you go is that there should be absolutely no ‘creep’ or cumulative error, which would result in frames not sitting on station.

 

Author:  Dan Vad.  Do what Greg and I did – measure EVERY frame position from the dead-flat to the squaring jig position as you get ready to fit it.  Mark it on the keel for reference to be double sure everything is lined up.


Author:  remcohe.  I would definitely put the fillers in while framing and not afterwards as I did.  Remco.

 

Author:  AnobiumPunctatum.  I would build all full frames first, before gluing them on the rising wood. I think it’s easier to correct the cumulative errors. 

 


Dec. 5, 2011.  I plan on making frames until I cannot stand it anymore before permanently mounting them.  I have not decided whether I like the aesthetics of the fillers but at the rate I build I will not have to worry much about that problem for a few months.  Unlike a lot of you more dedicated builders, if I get eight hours a week to build I am happy.

 

 

Author:  dvm27.  I place the steps on the futtocks on the outside of each bend.  This way, the spacers between the pair of frames are equidistant from bottom to top.  A small concession to accuracy perhaps but it guarantees that each frame in the pair (bend) is parallel when raised.  Concerning chocks vs. scarphed joints I actually find it easier to use chocks.  In a chocked joint you need only to mate one face of each futtock to the other over the plan.  After drying, the chock opening is traced over a bland and cut and fitted.  Quick work with a disk sander.  In a scarphed joint you need to mate the three faces of each futtock.  It’s a lot fussier work.  Of course, some of the toptimbers are designated with scarph joints on the framing plan so watch for these.  Greg

Dec. 10, 2011.  I have added the extension piece on top of the head of the knee.  This also tapers anteriorly.  Now that the counter timber and filling pieces are in place and partially faired, I have added the sills for the counter and bridal ports.  This was a real pain to do with all of the frames in the way.  I am glad that I waited until now because at this point I know the height and angle of the sills are correct.  The lower sills are cut with a bird’s mouth and the upper sills are cut with a wedge shape.  In the pictures it appears that the lower counter sill is tilted starboard but this is just shadowing.  I think that for the full frames I will add the cuts for the sills as I install the frames.

I am finding it rather difficult to make the beveled chocks for the frames  I know a lot of builders use a mill but right now that is on my someday list.  Until then, only 53 more frames to go!


 

Author:  druxey.  With a little practice and a very sharp chisel, plus really meticulous mark-out, making and fitting chocks will happen more rapidly once you get used to the technique.  It is extremely difficult to get a flat faying surface using files.  The surface will tend to round over as you file it.


 

Author:  Dan Vad.  Instead of using a file to finesse my chocks, I use a flat sanding board.  I run the angled faces of the chocks one side at a time on the paper by dragging them toward me.  It takes very little time to get the “feel” for the angles and how much pressure to exert on the leading or trailing edge.   Leave plenty of width when rough-cutting the chocks in case you sand a little too much off one of the angles and need to sand a bit more off the other face to compensate – the inboard face will be faired with frames in any case.


 

Jan. 8, 2012.  The frames are going a little quicker than anticipated.  Eighteen down and a whole bunch to go!  I decided to put chocks in all the frames.  It actually is easier than plain scarf joints because of the reasons Greg stated a last month.


 

Feb. 17, 2012.  I have finally finished all of the full frames (except for the cast toptimbers).  By finished, I mean that they are all assembled and sanded to the outside line on the frame template.  I have left the templates attached to the frames until each one is ready to mount to facilitate identifying them.  As I prepare to mount them I will add the cross piece, do the final sanding of the fore and aft faces and put in the trunnels.  The cross piece will be marked in the midline to help alignment.  The first frame mounted is 14A (aft).  The heels must be trimmed to match the shape of the bearding line and a wedge-shaped piece is removed from the floor to match the top of the deadwood after fairing.

I made a jig to help ensure that the frames are square and plumb.  I marked the midline and slotted the jig to fit over the keel.  I chose to make mine from heavy cardstock with wood supports.  I added a wood cross-brace and glued another piece of card on to the back to prevent warping. 

 

Framing Jig

post-262-0-81749100-1362093382.jpg  post-262-0-36909400-1362093395.jpg

 

I have drawn lines on the building board to represent the fore face of frames 14A and 14F.  As I add more frames I will continue to add these lines.  Everything is measured from dead flat.  The jig is then brought up to that like and squared true to the building board with machinist squares and contractor squares (at least that’s what they call them at Home Depot).  The frame is then seated and glued in place.  After the glue has set I will add spacer blocks at the top timbers.  When using the jig, remember the timber thickness decreases with each successive futtock and one face of the frame is flat but the other has a stair-step.  Frame 14A’s flat face is aft and the stair-step is fore.  Therefore the framing jig only touches the floor futtocks.  On frame 14F the flat face is fore and to the jig will be in contact with the entire frame.

Probably just a temporary brain freeze Toni but you wouldn't see a chock from the outside, only the joint between the frames. The outside looks the same regardless of whether the joint is chocked or scarphed.  To be honest, I am using chocked joints on Speedwell simply because I find them easier to do.

Thank you, John, for looking in.  Greg, I assumed when Remco wrote that he was referring to the final sanding of the fore and aft faces of the frames, not the inner and outer faces of the frames. 

 

It is interesting (and fun) to see the changes in building preferences and techniques in oneself over time.  I initially hated chocks and now see that they actually simplify the joining of two complex pieces of wood.  Before starting Atalanta I did not even own a chisel (unless the hand-me-down from my father-in-law that I use to pry open paint cans counts).  Now I don't even start a building session without having one out on the table.  I've transitioned from being a CA-girl to almost exclusively using carpenter's glue.  I'm sure we can all come up with a similar list.

Feb, 27, 2012.  The first few aft full frames are installed and I am in the process of fairing the inside of the hull.  For anyone fairing a hull I would recommend taking pictures of the progress and examining them for any irregularities.  There are things the lens “sees” that the eye does not.

 

Aft Faring

Author: dvm27.  When fairing, I rely more on feel than anything.  Running an open hand across the hull tells me when it’s as smooth as a sheet of paper.  Wait until all the frames are in before final fairing.  Greg.


 

Feb 29, 2012.  Greg, I found it necessary to do preliminary exterior fairing of the upperworks to get a feel for the true shape of the hull.  The lower hull will not be touched until all the frames are mounted.  I have mounted the first three fore frame pairs.  Once mounted, I sighted down the keel to make certain there was no twist in the hull.  This is most easily done with the camera.  The next two pictures show the interior and exterior of the bow before any fairing.

March 5, 2012.  I have started to fair the port side.  A moderate amount of fairing of the exterior was done on the lower part of the hull just to make sure the frames were correct.  It is amazing the amount of excess wood removed.  The inner fairing was done with a sanding disc on my Dremel outfitted with a right angle drive attachment followed by hand sanding.  The pictures show the partially faired port side and the unfaired starboard side for comparison.

March 19, 2012.  Frames 9-14 and F-L are mounted and the interior faired.  No exterior fairing has been done.  I have decided not to cut in the gunports and sweeps until all of the frames are in place.  (Next time I think I will pin the frames in place that require sill mortices, mark everything once all the frames have been erected, remove the pinned frames to cut the mortices off the and then permanently remount  the frames.)

April 13, 2012.  I wanted to get the topsides faired externally to make sure none of the frames needed to be reglued (or remade!).  With the spacers glued in between the toptimbers, the hull feels reasonably stable at this point to safely remove it from the building board.  The final fairing of the lower external hull will wait until the fillers are in place.  I have decided to install the gunport and sweep sills after fairing.  I think this will increase my accuracy in determining the sill heights.


May 11, 2012.  I have drawn out about 20’ of bamboo to start the treenailing.  I equate this task to putting in rat lines.  I started to mark out the gun ports and discovered that for two of the cast frames (nos. 4 and 8) I had placed the bend of the cast to superior.  These frames were removed and new top timbers were made.  Progress continues on the filling pieces I have found that the easiest way to tackle them is to make strips of wood the thickness of the largest space between the frames. Then, using a thickness sander, the strips are gradually thinned down and offered to the spaces between the frames.  The filling pieces add significantly to the structural integrity of the hull at this point.

 

May 23, 2012.  I have finished the filling pieces.  I used Swiss pear to give a little contrast with the boxwood.  In contrast to the pear that Danny is using in his Vulture build, this is less pink.  Maybe it is the age of the wood; these billets are 25 years old.  I initially installed port and starboard pieces simultaneously to prevent warping of the keel (thank you Danny for that lesson!) but once everything felt solid, I removed the hull from the building board and added them where ever they would fit.  I deliberately left out the filling pieces on the frames that had spacers for aesthetics and to allow a little light to enter the lower hull.  The pictures show them roughly faired in.  They will be finished after the gunports are completed.
 

Filling Pieces

I have begun cutting out the gun ports.  I read a lot of approaches and came up with the following.  The top edges of the lower sills were marked out on the hull by taking measurements from the Atalanta draughts.  These heights are a little different than shown on the Mylar. Next, I took a strip of blue masking tape (the kind that does not leave a residue) and ran a fair line along the hull connecting the marks.  Any adjustments to the sill heights were made now.  The lower edge of the upper sill was drawn in next, followed by the lower edge of the lower sill, sweep port and fixed block locations.

 

Now came the moment of truth!  I started in the mid-ships area so that I would not initially have to worry about replacing the top timbers.  The upper sill extends to the top rail.  I cut the timbers about 2 mm above the final location of the sill seat on both sides.  Then, a batten was placed through the opening s to confirm that the sill was level athwartship.  The ports follow the angle of the deck so the fore end of the sill is slightly higher than the aft.  The lower masking tape helps to prevent inadvertent damage to the frames and the upper tape adds a little extra stability.  Although difficult to see, in the last picture the batten in running between the ports.

The next order of business is to cut the birdsmouth mortise.  After marking it out I used an Exacto keyhole saw to mark the deepest part of the mortise. This helped me keep the Swiss files that were used to complete the mortise from wandering initially.  This is easier than cutting out the cant port mortises since these are at 90 degrees to the keel.  The sill was then slid into place.  In the second picture, the space between the sill and frame spacer needs to be cleaned out.  The upper sills have a triangular mortise.  Because this is amidships, all that was required was to cut down to the top of the mortise and file the angle.

June 4, 2012.  The gun port sills have been installed.  My biggest problem was keeping the sills level across the ship.  My solution was to take the glass bubble out of a level and place that directly on the sill.

Author:  Dan Vad.  I’d leave the fixed blocks until later (like after you finish framing the upper deck).  I don’t know how many times I managed to hit them when I was sanding parts of the deck.  They don’t stick out much but just enough to be a nuisance. Danny.

June 10, 2012.  I have completed all of the sweep ports and will begin fairing next.  The top timbers have been reinstalled above the gunports except in the waist where the top of the upper sill is immediately below the rail.  The two close-up photos
show the inboard and outboard surfaces. It amazes me how much detail is picked up in the pictures.  When I look at the model (even with Optivisors) I feel good about the appearance.  But looking at the pictures it appears like the work has been done by a six year old.  Sanding should take care of that!

Author: dvm27.  When you get down to your final sanding grit, paint a dab of white glue into any gaps where the sills are, then sand. Those gaps will virtually disappear.  Greg.

June 10, 2012.  A little 60 grit has helped quite a bit.  This photo is from the same part of the ship as the last photo.  I only broke out two cant frames and had to reglue several of the topline spacers.

 

Sweeps Sanded

June 25, 2012.  The last few weeks have been taken up with sanding and sanding and more…sanding.  I took Danny’s advice and glued a temporary batten to the exterior of the hull for increased stability.  I made no attempt to bend this around the bow.  I used a rather stiff plank (1 x 6 mm) which I placed at the level of the gun port sills and removed several of the spacers at the top timbers.  They will be replaced prior to removing the batten.  You can see this on one of the photos.

 

Although I am not finished with the internal sanding, I decided to fabricate the keelson.  This is made up of five pieces connected with hook scarfs.  The fore scarf will mate with the stemson.  The aft deadwood is different on Atalanta than on the Mylar.  I found it easiest to use a contour gauge to make a template of the shape.  I then transferred this shape onto adhesive paper, leaving a generous amount superiorly, which was easily removed later.  I still need to knock down the edges and notch one of the pieces for a crutch.   The photo shows the pieces separated from each other to highlight the scarfs.  The keelson is simply laid in place in the third photo.


Oh well, back to sanding.

July 2, 2012.  I have installed the stemson.  If there is a contest for the biggest pain-in-the-you-know-where piece, the stemson is right up there.  Between the hook scarf, the anterior shape as it meets the stem and the recesses for the deck clamp and breast hooks…  Speaking of which, the clamp anterior to the fore mast is in a slightly different location than on the Mylar.  This clamp straddles the scarf joint between the firth keelson piece and the stemson.  The keelson is 12” but tapers to 9” as it fays with the stemson, which is also 9”.  Bolts and trunnels are next.

 

I made an interior height gauge to obtain the correct elevations for the stemson recessed.  This will never win any beauty contests but it works well and did not require any metal work or “big boy toys”.  I cannibalized parts from my exterior elevation gauge and framing jig to make it.

July 16, 2012.  The  treenails are all in place and the hull has been sanded to 220 grit.  I planned on sanding the hull to 400 grit but today I felt like actually building something.  (As it turned out, not the best decision I ever made.)

 

Next on the agenda are the ribbands and harpins.  I decided to fabricate these and then finish the sanding prior to their installation.  I have yet to decide how much hull planking I will be installing and so the lower four pair of ribbands will be installed on both sides.  They can always be removed later and at a minimum provide a bumper for the hull, protecting it from damage.  This model travels with me in the car weekly because of my work schedule, so damage is a real concern.  From an aesthetic perspective, I am not sure I like the appearance of ribbands crossing through the gun ports, so the decision regarding installation of the topmost ribband will come later.  The floor ribbands are located 18” below the floor heads.  I have marked this out with masking tape.

I made the harpin first. This is cut out from 4” stock. Like so many items, this is one that looks deceptively easy but is not. There is the changing angle of the hull to take into consideration as well as the angle at which the harpin abuts the stem. There is a simple scarf aft.

 

Floor Harpin

post-262-0-64856100-1362512255.jpg

 

 

The ribbands are 4” square. I soaked the aft end of the ribband stock to fit the aft hull curve.  Both the ribbands and harpins are drilled and nailed at every frame.  At this point I have only drilled a few holes and installed some temporary brass pegs.

Things were going well and I was thinking of attacking the next pair until…

 

As I was taking the photos for the build long I repositioned myself and ended up giving the transom a kick in the rear end!  Needless to say, I did the only thing an insane model builder could do…take a picture and pour myself a stiff drink!

July 30, 2012.  I am still working on the ribbands and harpins.  These are not particularly difficult to make and install but the sheer number of steps involved means it takes a lot of time.  The harpins are made by taking a template of the shape of the hull and transferring the outline to 5” sheet stock.  They are actually 4” thick but the excess was sanded off afterwards.  I decided to make the ribband a single run of planking to give me the smoothest line.  There are five runs of ribbands and although it looks strange to me the topline ribband does run across the quarter light opening.

 

Once these were in place, they were nailed.  There is a nail hole at every frame as well as the hawse timbers and the toe of the harpin. This adds up to approx. 85 holes which must be marked, dimples, drilled and nailed.  TFFM recommends 24 g. brass wire which is left proud of the ribband.  He suggests rounding off the exposed end of the wire to simulate a nail head.  Unfortunately, there really is a difference in the appearance, so 85 holes times 5 runs times 2 sides plus a few extra for screw-ups…  Nine hundred nails to make.  (These will also be used later in the knees for the deck framing so add a few hundred more to that list!)


The white dots on the ribbands are drill holes filled with sawdust.  The black dots are the first three nails.

July 30, 2012.  Scale Hardware sells 0.4 mm headed rivets that will give the right look for the nails.  These scale out to ¾”.  They are expensive ($10/100) so I am only going to use them where the appearance is critical.

August 5, 2012.  I have installed the inner strakes.  The inner edge has a rebate for the limber boards and the outer edge is cambered to meet the thinner outer limber strake.  I make the rebate by lowering the blade on the Preac saw to 1.5 scale inches.  The cut-outs are for the well pumps.  The treenails did not stand out well in the photo so I wetted the wood to bive an indication of how they will look after a finish is eventually applied.  The apparent gap between the aft strake and the hull is shadowing.   You can see the difference in appearance between the keelson bolts and the scarf joint treenails as well.

August 5, 2012.  I will be using Watco’s Danish Wood Oil for my finish.  It is very forgiving and gives a matte finish if one coat is used and a low luster finish if multiple coats are applied.  I have not seen any change in color over the years .

 

Author: EdT.  Watco Oil is linseed and soya.  It will make the wood yellowish and will darken over time.  If you want no yellow use an acrylic.

 

Author: dvm27.  The Swan cross section was finished with Watco’s.  It does impart a tone to the wood, expecially holly which yellow a bit.  The finish is indeed flat after rubbing out.  The Echo cross section was finished with General Finishes water based sanding sealer (slightly thinned).  The box has not changed color at all, nor has my Pegasus after a couple of years.  I would use the Watco’s if you wish a richer color to the wood or the General Finishes sealer if you want to maintain the rough hewn appearance of a new ship on the stocks.  Greg.  The pictures Greg provided in the original build log were not preserved in the MSW crash. 

 

August 6, 2012.  The outer limber strakes have been added.  Thses taper down from a thickness of 3” to 2” at the fore and aft extremes. As this strake is only 10” wide, the treenails are in a single/double pattern.  The inner strake was 12” wide
and so had a double treenail pattern.

August 13, 2012.  The next stiffeners to tackle are the thick stuff at the floor heads.  There is an internal planking expansion drawing in TFFM. I enlarged it to full size and know it will be a tremendous asset in determining approx plank shapes.  The distances from the outer limber plank to the lower floor head  plank are copied from the expansion drawing.  I transferred the measurement to the hull and ran my masking tape “ribband” to fair the line.  This run of planking is 12” wide and comprised of four planks which taper fore and aft.  The foremost plank is cut out  to accept the fore end of the middle floor head plank.  All of the planks were bent by microwaving them in water, bending them to shape and allowing them to dry overnight.  Before installing them, the treenail locations were varked, pierced and drilled.  Pins hold the plank in place until the glue
dries.  These are blunt 22g pins used for beading.  The holes are 24g so the pins were thinned down with a grinding wheel on the Dremel.    The lower edge of the planks are cambered since the footwaling is thinner.  I have decided to omit the footwaling on the model so as not to completely cover up the internal frames.

 

The middle plank is thicker (14”) and narrows sufficiently in the bow to be dropped.  I made a template of the foremost plank with adhesive backed paper and transferred to to the wood.  The shadowing in the pictures illustrates the difference in the thickness between the lower and middle runs of planking.  The white color in the holes is sawdust.  Two bamboo treenails (tan in color) have been fitted in the fore end of the middle plank.

August 19, 2012.  I have finally finished the thick stuff at the floor heads.  The planks are drilled for treenails but they have not been inserted yet.  The middle plank is 1” thicker than the outer planks.

Elia, it is a pain to reconstruct the build log but at the same time it is instructive to review the process and look where I could improve things next build.

Author:  Dan Vad.  Now is the right time to make up the pump intakes and dry-fit them into the recess to make sure they fit properly.  I also suggest you make up the pump tubes (leave them at least 10mm too long for now) so you get a good idea on whether they fit into the inlets at the correct angles.  This will make later fitting a lot easier.  Danny.

 

August 27, 2012.  In the process of installing the upper strake of the lower deck clamp I looked at Greg’s photo on page 86 of TFFM Vol III. This shows that the top of the clamp extends to the bottom of the second transom.  On the Mylar I extended the top of clamp line aft, maintaining the same slight upcurve and it appears that the top of clamp should be below the 4th transom.  Danny’s and Remco’s clamp is at the top of the 3rd transom.  Mine is at the middle of the 4th transom. I have repeatedly measured using two different approaches and get the same elevation and the line “looks” fair. 

 

Lower Deck Clamp

post-262-0-87618700-1362618717_thumb.jpg post-262-0-25149800-1362618719_thumb.jpg

 


Author:  remcohe.  I measured the height of the lower deck from my NMM plans, took the thickness of the beams and the 1” letdown into account and there I marked the deck clamps and it just happened to end on the 3rd transom.  I don’t think any of the inner hulls of either build here is the same hence the differences where the clamp ends.  Remco

 

Author:  Dan Vad.  I did the same as Remco and finished in the same position.  There seems to be an anomaly somewhere, as neither of us finished on the same line drawn on the plans BUT everything further down the track (cabin bulkheads etc.) fell into place on both our builds.  Check the measurement from the top of the clamp to the top of the wing transom.  Danny.

 

August 27, 2012.  I measured the height from the top of the wing transom to the top of the clamp and, if anything, I am a hair high.

 

Author:  druxey.  There are differences in each vessel of this class.  The Mylar was drawn up from the Atalanta’s draught so it may be that the other Swans will spec out differently.  The ultimate question is whether the curves fair up properly.


August 27, 2012. After my last post I laid some battens in an X for to aft and everything looks right, so hopefully things will
turn out OK.

 

Author:  Dan Vad.  I’ve done a check on everything I could lay my hands and here and can’t find an anomaly in yours, but MINE is a bit too high.  It’ll be staying that way too.  No big deal though – the clamp runs well past the end of the lower deck at the aft end and hasn’t got any beams on it in that area.  It’s virtually invisible through the frames and upper deck work as well.  Danny.

 

Sept. 4, 2012.  I have installed the two lower deck clamp timbers.  First, I fixed a copy of the Mylar plan to a plank and used my height gauge to take off the elevation at every other station.   This was transferred to the hull interior.  Except for the extreme fore and aft stations, the gauge easily cleared the top timbers.  Once the height of the top of the clamp was determined, I used a straight-edge with a bubble level glued on to it to confirm that both sides were the same height.  (I made sure the building board was level first!)  These planks have anchor stock joints for extra strength.  I dampened the wood in the last photo to help them stand out.  After the planks were installed, I tapered them down from 4” at the top to 3” at the bottom of the run.

Sept. 24, 2012.  I have finally finished the Thickstuff of the first futtock head.  After these strakes were installed I put in all of the treenails for the six strakes of planking.  There were approx. 2100 treenails to install and it took me almost two weeks to complete them.  In the pictures you can see the different thicknesses of the strakes.  The top lower deck clamp is 4”, the bottom one starts at 4” and tapers down to 3”.  The wood has been moistened to show off the treenails.

Hi Toni,

 

Sorry if youve already answered this but what material are those 2100 treenail made from? Bamboo?

 

Beautiful work and thanks for doing such a detailed rebuild of your log.

Ben and Christian, thanks for reliving the past with me.  Ben, the treenails are bamboo.  Specificly, 6" skewers from the grocery store.  I look for the packages with the darkest wood.  I found that the wood in things like chopsticks was of higher quality (stiffer, straighter grain) but was too light in color.

 

I hope to have the rest of the log posted within the next week or two.

Sept. 29, 2012.  I have finished the three mast steps.  The mainmast step is straightforward.  It rests on the lower limber strakes and frames but does not extend into the bilge.  There is no for-to-aft variation in width but it cants aft one degree.  Although my step is glued in place, in practice the step was wedged into place between iron rods. This allowed the rake of the mainmast to be modified.


Mainmast Step 1, 2 and 3

post-262-0-68770700-1362791161.jpg  post-262-0-92827100-1362791159.jpg  post-262-0-59544300-1362791158.jpg

 

The foremast and mizzenmast steps are significantly harder to make.  Besides the obvious taper of the steps, the step sits on top of the floor head thickstuff.  The thickstuff also rises at the extremes (at least on my model) so the rabbets must be cut at an angle.  Finally, the top of the keelson rises so this must also be cut at an angle.  I started by making a template for the wider face of the step and cut the wood to this shape.  I then gradually “snuck up” on the taper by making very small cuts until I was satisfied with the fit.  The foremast step is perpendicular to the bottom of the keel and the mizzenmast step is canted three degrees aft.  They are secured with eight 1” bolts (blackened 24g brass wire).  Unfortunately, the mortise cut previously for the dropped plank of the floor head timbers is now completely hidden by the knee.  Another one of those “but I know it’s there” situations.

 

Foremast Step 1, 2, 4 and 5

Tony,

 

has it a reason that you do not show all filling pieces at the lower hull? I am thinking what I shoul show and what not. If I remember right, Greg doesn't show any filling piece.

I left out the filling pieces on the frame pairs that had spacer blocks.  I wanted at least a little light to get into the deeper parts of the hull.  By choosing this location I maintained a continuous connection between all the frames  to minimize the chance of the hull twisting.  Greg has filling pieces on Pegasus but they do not show up well on his pictures.  If I look at my hull at shoulder level or lower you cannot see them either.  I also made them of different wood (pear) as suggested in TFFM.  I probably would not do that on the next build.  It gives the hull a "zebra-stripe" look that I personally don't care for.

Sept. 30, 2012.  I have come to the first project which requires a decision about how to build out the interior of the hull.  I have decided to leave the starboard side open for viewing as much as possible and completely build out the port side (except for the Footwaling).  The next items to install are the limber boards.  These are supposed to be approx. 36” long except under the hatches (18-24”).  I marked out the location in the bilge for the hatches, fore partition and well.  I then divided these spaces evenly and came up with long boards of 32” and short boards of 20”.  The second photo shows two long boards and three short ones.

 

Limber Boards

post-262-0-50989100-1362849715.jpg  post-262-0-68820700-1362849714.jpg

 

The aft crutch was next.  It really does nook better in real life than the photo would suggest.  I know there is a problem with the height of the top board of the aft deadwood but I could not figure out a way to rectify it at this point so I simply glued the crutch on to the top of the deadwood.  The crutch and the breast hooks are perpendicular to the angle of the keelson/deadwood.  This just adds a little more complexity to their fabrication.  Unlike the crutch and fore/mizzen mast steps, the breasthook bolts are structural, not decorative.

Oct. 8, 2012.  I made one of the sleepers.  These are knees that cross the lower transoms and the cant frames.  This one cannot actually be used because the rest of the thickstuff has not been installed.  There are supposed to be two bolts per transom according to TFFM but this just does not look right.  Any thoughts?

Author:  remcohe.  Those are tricky to make.  I just did one bolt per transom in a zig-zag pattern.

Author:  druxey.  One bolt per timber certainly looks neater.  Those sleepers are very awkward to fit, and it looks like you’ve nailed it, Toni.  I mean, bolted it.  That doesn’t sound right either…

Thanks for the info, Toni

 

I use pear for the framing and have some pieces of different stock. I think this will make a light visible contrast.

Oct. 8, 2012.  The next project to tackle is the aft platform.  On these smaller ships, there was no orlop deck so the fore and aft platforms served the function.  The location of the platform beams were taken off the draught.  The difference in length from the draught is a combination of probably removing too much wood during fairing and the thickness of the inner planking.  There are two bulkhead walls which intersect the first two beams.  These are the fore and aft fish room bulkheads.  The planks are 2” x 9” and are cyphered or bevel-cut on the long edges.  I made the planks 2” x 6” and eliminated the cypher as this will never be seen and I do not have a disc sander or a tilt table on my saw to get a consistent bevel.

 

There are two stanchions on the fore face of the fore bulkhead.  These mortise into the limber plank and the fore platform beam.  You can see the mortise and tenon for the platform beam.  The limber plank connector will be a brass pin which I will insert when the platform is ready to install.  I will be planking the port side and leaving the starboard exposed.

Nov. 5, 2012.  I have completed the framing for the aft platforms.  The port side will be planked and so I have not installed all of the ledges.  The mortises are all made with the diagonal cut technique rather than a step-mortise.  I will try the other technique when I make the fore platforms.  As I do not own a mill, the mortises are made with a razor saw and finished up with and 11 blade scalpel.  The platform actually looks much better than the photos would suggest.  Since I am not installing Footwaling, there is a gap between the lateral edge of the platform and the hull framing.  As this platform will basically be invisible once the model is completed, I omitted the fasteners in the knees.

In order to complete the aft platform, the aft lower deck beams must be temporarily installed.  There are pillars extending from the beams to the keel and these pass through the platform.  There is a 3” roundup on the lower deck.  Everyone has their own technique for shaping beams.  My approach is to make a template of the roundup on thin balsa.  I then draw this line onto an oversize beam blank.  Using a spindle sander (a disc sander would be better but I don’t own one) I shape the top of the beam almost to the line and then finish it with sandpaper.  Next, I fit the beam to the lower deck clamp.  The beam is let 1” onto the clamp.  Finally, I mark out the lower edge of the beam and repeat the process used on the top.  The hardest part is getting a tight fit against the hull because of the compound curves.  There is no footwaling so I should be leaving a 2” gap at the end of each beam.  I did this and it looked sloppy.  Therefore, I took builder’s license and extended the beams out to the hull timbers.  After placing the beams on the clamps, I was thrilled to see that a straight-edge placed in the midline on top of the beams was flush with the beams.  Final sanding and shaping fore and aft will wait until the beams are permanently installed.
