Young America 1853 – POB 1:96
Part 16 – Garboard Strake

 

The planking of the lower hull begins at the keel with the installation of the garboard strake, heavy (7” X 18”) members, bolted through the deadwood and edge bolted into the keel.  At the ends of the ship the garboard strake is expanded into two strakes to begin the upward sheer of the bottom planking and to further strengthen to narrow deadwood at these points.

 

In the first picture the aft section of the garboard has been fitted against the post and is being marked for the insertion of the second strake “stealer”.

In the next picture the strake was cut to receive the second section and is being held in place to check the final fit..

 

post-570-0-45660300-1440419765_thumb.jpg

 

This strake members were then glued in place as shown below and over the entire length of the hull with a similar joint for a second strake at the bow.

 

post-570-0-79231400-1440419765_thumb.jpg

 

Because this strake twists to fay against the curving hull, a lot of clamps were needed.  The next picture shows the aft section after the piece of second strake was installed.

 

post-570-0-25222800-1440419766_thumb.jpg

 

I did not use dark glue for any of the hull planking since the intention is to paint and sheath the hull later.  Hard maple was used for all of this planking.

 

The last picture shows the forward part of the garboard, with the joint lines emphasized on the image to show the configuration.

 

post-570-0-12032700-1440419767_thumb.jpg

 

In this picture, it can be seen that the line of the rabbet runs just aft of the joint line between the stem and false stem.

 

Note that in the last two pictures the garboard thins down to match the depth of the rabbet in the stem and sternpost.  The garboard was, of course, installed on both sides of the hull at this stage.  Since it is intended to sheath this lower hull, I did not install any of the bolts, as I would have done on the fully framed version – if I had installed the garboard on that model. 

 

Above the garboard, the planking thickness drops to 4”.  The beginning of that work will be shown in the next part.

Ed.....your doing a fantastic job on this build of the YA.  I just want to let you know you are a super encourager and motivator for the skilled model making minded individual. Only one other example that I have found can equal or at least be near to your superb vessel is this fine reproduction.

 

I thought I'd post this pic so as to demonstrate the near exactness to your own model.

 

Amazing....both..no..all three are amazing.

Thanks, everyone for all the likes and the comments.  That certainly is a beautiful model, Rob.  I do not believe I have seen it before.  I note the black main rail, which is evident in the two existing photosof the actual ship.  I followed Bill Crothers advice on paint and made mine white and that introduced some complexities into the build to avoid having to paint that line after construction.  The black looks so good I am not sure it was worth the effort.  Bill certainly had access to the photos before recommending the paint scheme, but his source is not clear -  at least I have not turned it up yet.

 

I also note in the model picture that the fancy rail along the top of the side is also painted black and that the top of the side rises above the poop deck and is therefore higher along the other decks as well.  This may not be correct and differs from the design I used.

Yes there are some slight differences....the poop deck rise may indeed be an error, but who'e to say it wasn't Crothers, since he obviously got the fancy rail paint color wrong...well at least from any photo documentation I have ever seen of the actual ship and respectable paintings of her.

 

One thing I think can be an explanation...like most commercial vessels..they did undergo changes and modifications during their careers..I know this to be oh so true with one of my favorite McKay vessels...Glory of the Seas.  I have extensive documentation on her and it depends on the year as to what you might consider adding or detracting from her deck furniture to her rigging and masting.  All in all..do to the inadequate collection of true accurate images and a good living example..a well executed likeness of any American clipper is almost as good as one can get(Unless you have the actual mechanics plans to work from)

 

Did I mention you are doing a fantastic job?   :dancetl6:

Thank you, David.  I hope the book measures up.  And thanks for all the likes on this log.  I have intended it to be a useful supplement to the POB related text and pictures in the book.  I feel I have been neglecting the full framed "big sister" for the past couple months but hope to be back posting on that log soon.

 

Rob, you are right about changes in service and painting would seem to be the most likely to vary.  I would not be too quick to judge Bill Crothers wrong on this - the paint scheme of the original ship.  He was generally very meticulous about his sources.  The two known photos showing the black main rail were taken years after the launch as indicated by the single stick upper masts that were not in the original design or even in the configuration of 1854 when the Howes double topsails were added.

 

On the levels of the deck relative to the topside, I spent some time looking at this when drafting the plans for YA, because the poop rail seems very low relative t the deck height.  However I soon found that Webb's initial offsets are quite definitive as is one of the photos that clearly shows men standing on the poop at the level of the fancy rail.  The height of the poop rail may also be measured from this photo.  The heights of the planksheer rail given on the original offsets, coupled with the known depth of the main deck waterway, leave little doubt as to the correct deck heights.  So I guess you could say that Webb himself has the last word on this question - in what seems to be his own fine hand.

 

Cheers,

 

Ed

Surely..I meant no disrespect to Crothers concerning his estimations of original color schemes of said portion...however it is true as you have duly noted that changes did occur..even photographic evidence suggests this.  I only pointed out that any error could find its origins in many places.  Since, not too many folks are still living who actually sailed on such vessels to gather first hand accounts from....we can defer to qualified experts such as Crothers and the like.  I for one rely heavily upon Crothers for my many builds.

My purpose in the note was to ensure people were not left with the impression that the white main rail was wrong or that there is any real question about deck heights.

Young America 1853 – POB 1:96
Part 17 – Bottom Planking

 

I have mentioned a number of times that the 1:96 POB version shown in these posts was constructed as a demonstration model for the book (now available from SeaWatch).  After reaching this stage in the build, the text in the book applies equally to both models and the same methods apply to complete either model.  For all of that subsequent work, the 1:72 model was used in the descriptive photos to avoid confusion and the excessive space requirements to show both.  Although I believe the book describes both versions well, I thought that anyone wanting to build the POB version would find the many pictures I was taking useful and interesting.  For that reason (and because I was having fun with this version) I decided to take it to a further state of completion and post pictures of that work here.

 

There is no bottom planking on the fully framed model, but this version would clearly require full planking to cover the bulkheads and spacers.  The first picture shows the first several strakes above the thick garboard being installed.

 

post-570-0-62993400-1441027397_thumb.jpg

 

I used hard maple for all this planking.  The picture shows typical clamping.  Thumb tacks proved very useful and easy to use on this work.  The soft pine spacers between bulkheads allowed these to be pushed in by hand but some required tapping with a hammer.  The clamps were used to close the planking joints in the very lowest strakes.

 

The next picture shows the planking being levelled off next to the thicker garboard using a flat #0 cut riffler, one of my favorite tools for this kind of work.

 

post-570-0-45772000-1441027398_thumb.jpg

 

The bottom planking is 4” thick above the garboard.  I ripped the planks to 5” to allow for some smoothing out and some finish sanding.  Since all of the planking on this model would likely be painted or metal sheathed, I dispensed with pre-painting the edges of the planks and the use of dark glue.  The next picture shows some work near midship.

 

post-570-0-95834900-1441027398_thumb.jpg

 

Drawing pins also work well in the pine substructure as shown in the next picture, but in general I used thumb tacks.  The type with plastic covered heads are best.  With the tapping in and prying out the attrition rate on thumb tacks was high.

 

post-570-0-50065900-1441027399_thumb.jpg

 

The clamp shown at the stem applies quite a lot of pressure to hold the “hooding ends” tight in the rabbet.

 

As planking begins to proceed upward, additional strakes need to be cut in at the ends so that the planking will eventually match the sheer of the wale above.  I began inserting these - as shown in the following pictures – when the lines of planking began to appear drooped at the ends when viewed from the side.  In the first picture the cutting in point is being marked.

 

post-570-0-92111700-1441027399_thumb.jpg

 

In the next picture the installed plank is being pared back to one-half its width while preserving a fair line forward.

 

post-570-0-44369600-1441027400_thumb.jpg

 

In the next picture the partial strake has been fitted and is, itself, being marked for another cut in strake.

 

post-570-0-95720400-1441027400_thumb.jpg

 

In the next picture that strake is being glued in place.

 

post-570-0-44175300-1441027401_thumb.jpg

 

Although difficult to see in this last picture, the same process was applying at the stern.

 

post-570-0-97364500-1441027401_thumb.jpg

 

At about this point, work on the lower planking was discontinued until later and the focus shifted to the upper works where much work awaited.

Druxey,

 

Actually, I was referring to the thickness of the planks, not their widths.  The width of the planking on these ships was usually about 6" - rather narrow compared to what most of us are used to.  I used a common width of 8" below the wale.  I do not intend to actually sheath this demo model or paint it below the waterline, so 8" seemed a reasonable compromise.  I take your point though.  It was a lot of work - even with no treenails.  I also left the port side unplanked from somewhat below the top of the wale - to display the bulkheads and spacers.  I am planning to bring this model - and big sister - to the NRG conf.

Young America 1853 – POB 1:96
Part 18 – Fairing the Upper Works

 

When the hull was faired earlier, in the inverted position, little attention was paid to the upper works, so the outside of the toptimbers needed some work.  The sanding required to fair the outside of these was light.  The first picture shows this in progress using 220-grit paper on a Softsander® foam pad.

 

post-570-0-12816600-1441200115_thumb.jpg

 

In the next picture the fairness is being checked with a pine batten.

 

post-570-0-67084700-1441200115_thumb.jpg

 

The toptimbers were molded 6” at the top.  In the next picture this is being checked with calipers. 

 

post-570-0-12490300-1441200116_thumb.jpg

 

You can see from the reading that they are still oversized somewhat at .076”.  They would later be faired to the final 6” (.0625”) by sanding the insides – but only after some reinforcing outer planking was in place.  However, it was necessary at this stage to fair the deck “beams” accurately – as shown in the next photo.

 

post-570-0-58119900-1441200116_thumb.jpg

 

Fairing of the deck was particularly important to avoid waviness in the thin deck planking that would be added later.  In the next picture this is being checked during the sanding process using a pine batten.

 

post-570-0-08221100-1441200117_thumb.jpg

 

When this work was being done, I did not expect to take this model to much further and consequently spent less time getting the deck line faired than I should have.  I will show the final deck planking later.  While acceptable, more attention at this stage would have yielded a truly beautiful installation of the long, spacious open main deck..

 

With this work completed, the construction of the topside planking and rails could begin.

The Book is out!

 

I hope I may be permitted some euphoria over the publication of Modeling the Extreme Clipper Young America, Volume I.  It took a lot of effort by Sea Watch Books and me to get this to market this year.  There were times early in the year when the amount of modeling and writing required to meet this deadline seemed insurmountable.  All the generous and supportive responses to the two build logs on this site helped us keep our nose to the grindstone.

 

The picture below of the book and its supplementary material hardly does justice to Derek Gardeners beautiful rendering of Young America on the Irish Sea on a winter’s morning as she approaches Liverpool – but it does serve as proof that the book is in print.  I have examined every inch of this first copy and am delighted with the result.  We hope you will be as well.

 

As I did with the Naiad books, I will start a topic in the book review section for comments, questions, addenda, and what I hope will be very few corrections. In the meantime, this posting on each of the two build logs will at least serve notice that the book is out.

 

Thanks again for all your support.

 

Ed

Young America 1853 – POB 1:96
Part 19 – Planksheer

 

In the angle between the toptimbers and main deck beams, a massive 12” x 11” waterway was fit to reinforce the deck beam connections to the frames and to provide a watertight seal around the outer deck planking.  The planksheer was a large member that fit directly on top of the waterway and enclosed the toptimbers.  It provided a watertight cap over the hull frames, waterway and outboard planking.  It was wide enough to show as a molded rail both outboard and inboard.  It was either mortised to fit down over the toptimbers or, more likely, made in two parts that were notched to fit both inside and outside, then bolted through horizontally.  On the model, I installed the planksheer as spacers between the toptimbers capped by rails inside and out.

 

Since the planksheer rests on the waterway which in turn rests on the deck beams, I believe the height of the planksheer is most accurately set by fitting the inboard rail first.  The height was set using a temporary pine spacer cut to the depth of the waterway.  This is shown in the first picture.

 

post-570-0-48858700-1441973865_thumb.jpg

 

Why not install the waterway first, then the planksheer?  If the model is to be painted, the waterway will be painted blue, the inboard works, including the adjoining inboard planksheer rail white.  To avoid having to cut in sharp paint lines after construction, I wanted to paint the white then install the pre-painted blue waterway below it.  The natural finish decking would later be installed against the blue waterway. The sequence to accommodate painting is also described in the posts for the 1:72 framed model – as well as in detailed in the book.  The inside rails were molded using a scraper and cut to size as described for the larger version.

 

With the inside planksheer rail glued in place to the toptimbers, spacers between toptimbers were cut and fitted – glued to the outboard face of the inner rail and end glued between toptimbers.  In the next picture, these spacers have been installed and their outer edges are being faired to the outside of the frames.

 

post-570-0-04988600-1441973866_thumb.jpg

 

In the next picture the tops of the spacers are being filed flush with the top of the inside rail.  The upper face of the rail is horizontal in the athwartship direction.

 

post-570-0-42733900-1441973866_thumb.jpg

 

Before the outer part of the planksheer or any exterior planking could be installed, it was necessary to fit the knightheads.  I will describe that work in the next part.

Ed,

 

super accurate planking Job....

the wood filling between the Frames Shows the benefit of this method when using tacks with wide heads to fix plank positions (without penetrating the Planks)

Very nice Pictures also, thanks for sharing.....

Young America 1853 – POB 1:96
Part 20 – Knightheads

 

The knightheads reinforced the stem on either side and provided a base for securing the hawse timbers that formed the forward hull back to the first cant frames.  This detail is shown in the posts for the full framed version of the model.  Rising above the top of the sides, the knightheads also provided lateral support to the bowsprit.  To accommodate the 36” square section of the bowsprit, additional space was provided between knightheads by additional members, 10” thick stem timbers, bolted to the sides of the stem assembly.  The two 10” stem timbers astride the 16” thick stem provided the necessary 36” spacing for the bowsprit.

 

On the POB model only the upper parts of the knightheads and stem timbers were modeled.  In the first picture their patterns have been pasted to the correct size stock.

 

post-570-0-99856000-1442326469_thumb.jpg

 

As with all of the stock for this demonstration model, ¾” wood was used, allowing all the thicknesses to be cut on a good model circular saw.   This was done to allow the model to be made from readily available stock without the need for a thickness sander/planer – a rather expensive tool and not one that beginning scratch builders might have.  In the next picture the members have been cut out and given an initial bevel based on the pattern lines.

 

post-570-0-43657600-1442326470_thumb.jpg

 

These were cut from hard maple.  The knightheads will be exposed on the model but painted black.  The members to the right are shown in their relative positions.  In the next picture the starboard head timber is being fitted into the space between the stem and the most forward bulkhead.

 

post-570-0-92524400-1442326470_thumb.jpg

 

To prepare for this, the pine spacers forward of the first bulkhead were removed by sawing and paring with a straight chisel.  These spacers had been installed to protect the forward bulkhead during initial rough fairing of the hull. 

 

In the next picture the breadth across the installed head timbers is being checked for the eventual fit of the bowsprit.

 

post-570-0-52434400-1442326471_thumb.jpg

 

At 1:96 the breadth needs to be 3/8”.  This precise breadth was obtained by sanding the sides of the members after they were glued in.  In the next picture the port knighthead is being glued into place.

 

post-570-0-93398900-1442326471_thumb.jpg

 

With both knightheads firmly secured they could be faired into the stem rabbet.  In the next picture a gouge is being used for this.

 

post-570-0-45259200-1442326472_thumb.jpg

 

With the shape roughed out with the gouge, a curved rasp was used to refine it – as shown below - followed by 120-grit sandpaper.

 

post-570-0-96125400-1442326472_thumb.jpg

 

With the knightheads in place and faired, the topside planking could begin.

Young America 1853 – POB 1:96
Part 21 – Topside Works 1

 

Because of the fragility of the plywood toptimbers, a slightly difference sequence was followed in constructing the topside bulwarks on POB model vs. that used on the full framed version.  To reinforce these toptimbers and allow them to be faired and sanded smooth on the inside, the top strakes of planking just above the main rail were installed first – beginning at the elliptical stern.  These two upper strakes were installed using one planking strip.  In the first picture a strip has been boiled for bending and is clamped around the stern at the top for drying.

 

post-570-0-95150900-1443445362_thumb.jpg

 

In the next picture, a final check of the height of the stern at the centerline is being checked against the drawing using the height gauge.  Last chance to make sure the height is correct.

 

post-570-0-40681700-1443445363_thumb.jpg

 

The decking of the poop was flush with the top of the side planking, allowing the fancy rail to cap the side and deck planking.  In the next picture a gauge strip of deck plank thickness (3 ½”) is being used to check the side planking height as it is glued and pinned in place.

 

post-570-0-92055300-1443445363_thumb.jpg

 

The top plank was then continued forward to the stem as shown in the next picture.

 

post-570-0-39841500-1443445364_thumb.jpg

 

The height gauge was used throughout the installation of this upper strake to ensure an accurate line.  The next picture shows some more of the installation of the upper strakes.

 

post-570-0-89504800-1443445364_thumb.jpg

 

Once the work has proceeded forward of the poop deck and the plywood bulkheads, clamps were used in lieu of the pins as the planks were glued.  In the next picture the upper side strakes are complete and the tops of the timbers are being levelled off at the correct height using a fine rasp.  This could not be done safely without the upper strake in place.

 

post-570-0-73990500-1443445365_thumb.jpg

 

Before sanding the insides of the toptimbers, outboard planking between the main rail and planksheer rail was installed.  I will cover fitting of this planking around the stern in a later post.  A temporary spacer was used to set the gap that will eventually be filled with the painted main rail.  In the next picture the planking down to the planksheer has been installed and the insides of the toptimbers are being faired with a Softsander® pad fitted with 120-grit paper.

 

post-570-0-44985600-1443445366_thumb.jpg

 

In the last picture the insides of the toptimbers are being sanded smooth with 220-grit paper.

 

post-570-0-96599800-1443445366_thumb.jpg

 

At this stage the upper works were quite strong, the toptimbers sanded smooth and ready for the next step – installation of the inboard parts of the main rail.

In the last part, planking between the main rail and planksheer rail was shown installed.  This planking is straightforward once the strakes around the elliptical stern are in place.  It’s just a matter of continuing these forward to the stem.  Fitting the strakes around the stern is a bit more complex, so I wanted to backtrack to show that work in some detail.  The installation closely parallels the same work on the framed version, but is somewhat simpler because thumbtacks may be used into the solid filler block, whereas on the framed model the curved strakes had to be clamped to the stern timbers.  

 

In the first picture the main rail has been boiled and is clamped around the stern to dry just below the top planking strakes installed in the last post.

The shape of this molding was scraped before boiling.  When dry, the piece will be used to space the planking strake below.  It will not be permanently fixed until much later after it and the hull have been painted.

 

In the next picture the stern is being given some light final trimming with a rasp before beginning the planking.

In the next picture the first plank below the main rail has been boiled, bent to shape, pinned in place and allowed to dry.  The main rail shown in this picture is only temporarily fitted as a spacer.

Because these planks are curved in two planes, it is difficult to get a perfect fit to the plank above without some trimming before final gluing.  This was done as each strake was installed – to get a neat fit with the one above.

 

The next picture shows the third strake below the rail tacked and pinned in place for drying.  The gaps in the joints with the adjacent strake above can be seen.

In the next picture the second strake is being trimmed with a paring chisel to accept the next plank.

Both sides of the joint got some slight trimming.  In the next picture the curved third strake is being checked for fit with the one above.

This strake is being glued in place in the last picture.

To allow for the trimming and fitting of this planking – and also the final levelling –

 planking strips were slightly oversized to start. 

 

I find this method of fitting these curved and twisted planks less work than spiling.  The two dimensional curving of the planking strips requires significant boiling time (say an hour) and use of an easily bendable wood species – in this case straight-grained hard maple.  I doubt that this degree of shaping could be achieved with kiln-dried Castelo that would be a likely choice for an unpainted model.  This one will be painted.

Hi Ed, 

Since last week  i am a proud owner of your book. Outstanding, I must say. one question though: i have no American legal or letter sized paper, can the bulkhead patterns for the 1/96 version be printed on A4 paper too, and if so what must I change in the setting on the pdfs?

Thanks again for your fabulous work on clipper ship model building.

Greetings,

Rudolf

Rudolf,

 

Thank you for purchasing the book.  I hope it meets your expectations.

 

It should be no problem printing any of the pdfs on A4 paper.  A4 is slightly narrower and also longer than letter sized, but the pdfs will fit.  When printing from Acrobat or reader, simply click on page setup and change the printer paper size to A4 or do this in Printer Properties.  Also make sure that "Actual Size " or "100%" is checked.  Just to be sure,, check one of the dimensions after printing - for example the maximum breadth on the pattern for the deadflat.  

 

Good Luck.  Let me know how it went.

 

Ed

Part 23 – Mooring bitts, Boomkins

 

Before moving on to the hull planking, I decided to work on some structural details topside.  The first of these chores was to install the aft mooring bitts and the horizontal timbers – boomkins - that extend outside of the hull to support the main yard braces and some other rigging.

 

Because the plywood bulkhead spacing along the poop deck does not correspond to the actual poop deck framing, some surgery was needed to fit these structures.  In the first picture a slot is being cut into the top of bulkhead 48 to fit one of the aft mooring bitts.

 

post-570-0-62008100-1444480785_thumb.jpg

 

The next picture shows the slot being chiseled out on the other side.

 

post-570-0-10396000-1444480786_thumb.jpg

 

In the next picture the two after bitts of the pair are being glued in.  They will be cut down to size and shaped later.

 

post-570-0-53701900-1444480786_thumb.jpg

 

With these in place, wood chocks were fitted to both sides of the installed bits and between bulkheads 48 and 46 – to secure the forward bitts of each pair.  The forward bitts are being glued in place in the next picture.

 

post-570-0-02775400-1444480787_thumb.jpg

 

A temporary pine spacer was placed between the bitts to provide correct spacing for the horizontal boomkins. Note the height of the outboard planking around the poop.  This will permit the deck planking – specifically the margin plank - to be set flush with the top of these planks.  This joint will be covered by the wide “fancy rail” at the top of the side.

 

In the last picture the outer wood chocks and the outer planking have been notched and the boomkins fit between them.  These too, will be cut to length and shaped later.

 

post-570-0-53896100-1444480787_thumb.jpg

 

The spacing between the bitts is actually smaller than the size of the boomkins, so they had to be mortised to fit into the allotted space. 

 

This last picture shows supporting chocks for the mizzenmast installed – at the top left of the photo.  Because the bulkhead spacing is on main frame lines (Stations) only, there are no intermediate beams, carlings or headers for support of the various above-deck structures.  Wood spacers, chocks, etc. have been put on the drawings for this purpose and will be installed in the next part.

Part 24 – Main Deck Structural Work

 

The simplified POB model leaves open spaces in the deck structure that on the framed model is filled with intermediate beams, carlings, headers and ledges.  These provide under-deck support for the various main deck facilities.  Support for these facilities – cabins, hatchways, mast partners and the like – had to be added to the structure of plywood bulkheads before planking the decks.  These supports will be invisible in the finished model, so they are made from simple pine chocks glued to the bulkheads.

 

In the first picture the spacing for the main mast partners are being measured out from the centerline.

 

post-570-0-88598900-1444684393_thumb.jpg

 

In the next picture pine chocks have been fitted and glued between bulkheads to give lateral support to the mast.

 

post-570-0-44473200-1444684394_thumb.jpg

 

In the next picture a virtual platform of pine chocks is being glued between bulkheads to support the poop deck facitites – the coach, the two skylights and the helm housing.

 

post-570-0-82741900-1444684394_thumb.jpg

 

The mizzen mast supports can also be seen in this picture.  In the next picture a thick pine strip is being glued to bulkhead 10 to support the aft head ledge of the main deck cabin.  Clamping is important when installing these to ensure good glue joints.  Aligning the grain of the pine pieces with the bulkheads is also important to avoid weak end-grain joints that will open up later.

 

post-570-0-37320800-1444684395_thumb.jpg

 

The last picture shows the model with all the necessary supports installed.   To avoid missing any of these, all necessary supports were put on the hull structural drawings.

 

post-570-0-18446300-1444684396_thumb.jpg

 

With all this crude structure in place, the deck was given a final sanding to fair the lines of the bulkheads and also to make the pine chocks conform to the deck round up.

 

With this necessary but dull work out of the way, I returned to hull planking.

Part 25 – Hull Planking

 

The next task on the model was the hull planking.  As with the topside planking, it began with the curved strakes around the stern.  In the first picture the planksheer rail has been scraped to its profile, boiled for an hour or so and clamped in position around the stern.

 

post-570-0-22810100-1444827744_thumb.jpg

 

Screw clamps were used for this piece.  It is not only curved around the stern but also twisted to be horizontal and not tilt downward.  Straight-grained maple was used for all the bottom planking.  Its flecked grain will be hidden by paint and metal sheathing.  You will note in this picture that the topside planking above the planksheer was not yet installed.  This would, of course, be installed before extending the rail forward.

 

In the next picture that rail has been allowed to dry and then glued in place and the next strake has been boiled and clamped for drying. 

 

post-570-0-64401300-1444827744_thumb.jpg

 

The strake shown above is also highly twisted to conform to the almost horizontal counter at this point. When planks are boiled it is essential that they dry thoroughly and shrink back to normal size.  Premature gluing will result in shrinkage gaps between strakes.  Waiting for these boiled strakes to dry is time consuming, so other work was done in parallel as shown in the next picture.

 

post-570-0-21791100-1444827745_thumb.jpg

 

In the above picture the planking is proceeding up from the bottom in parallel with the work at the stern counter.  The next picture shows the fourth and final curved stern plank clamped and tacked in placed for drying.

 

post-570-0-63462700-1444827745_thumb.jpg

 

The thumb tacks and the wedge against the sternpost serve to keep this strake tight against its neighbors.  In the picture the strakes above have been trimmed by sanding - after drying and before gluing to fit up tightly with the previous planks.  They were slightly oversized initially to allow for this final fitting.

 

post-570-0-49868100-1444827746_thumb.jpg

 

 In the next picture this fourth strake is being glued in.  The hull is wet from washing off excess glue.  The thumbtacks used here have plastic coated heads and are the preferred type.  The plastic helps cushion them and reduces damage to the planks.  The plastic also prevents wood discoloration caused by wetting uncoated metal heads.

 

The next picture – taken at the same time – shows the progress of lower planking.  To keep the plank in fair lines, stealers (dropped strakes) were used as needed.  Some of the process for this will be shown in the next post.  It is thoroughly described in the book.

 

post-570-0-19237700-1444827747_thumb.jpg

 

The next picture shows straight planking below the planksheer rail being glued down.  The solid soft pine hull allows hammering down of the tacks – making pinning down easy.

 

post-570-0-72373900-1444827747_thumb.jpg

 

In the next picture a screw clamp is being used to close the gap between strakes.  This can only be done where there is something for the clamp to grip – in this case the top of the side.

 

post-570-0-52987000-1444827748_thumb.jpg

 

In the next part the remaining planking on this side will be described.
