  1. Ed,

     

    I was a bit concerned about my choice of using the rubber cement because of your comment regarding not being a fan of it.  So far it seemed to have worked well ... but it is quite early in the game yet.

     

    On another note,  I will be cutting some monofilament line from my fly rod reel to test using it as per your response to my PM.  Possibly it needs to be roughed up a bit for the glue to anchor in.  Of course it is much lighter and GREEN as opposed to the black line you just used on your YA to simulate the bolts.  If it works I'll need to purchase a supply of black line.... that or copper wire and blackening.

  2. Today I finally started... sort of

      - milled down a strip of hemlock to the larger (inboard) thickness of 2'-2" (= 0.406" at 1/64th).  I managed to get 0.4045"

      - rubber cemented my templates to the strip of wood

      - rough cut out my very first piece staying close to or just outside the line

    post-9868-0-55464000-1422828523_thumb.jpg

     

      - cut all other pieces

    post-9868-0-46136800-1422828562_thumb.jpg

     

      - sanded into shape and fitted together

    Everything looks reasonably good when clamped finger tight  ... except for the Gammoning Knee pieces.  The outer (forward) half does not sit correctly.

    Flipped it over to inspect the reverse and again it is those two piece

    When I remove them they fit together nicely all on their own.  Time to walk away and come at it fresh another day.  Not sure if this piece is salvageable or not.

    I am obviously no cabinet maker and think I might need a small oscillating drum sander to assure I get a level sanded edge on those inside radii.

     

    I took a lesson out of TFFM.  I milled a piece of oak to use as my chiseling base when cutting the scarphs and it made a big difference.

    (Thank you David and Greg for a wonderful reference)

     

  3. I finished up my modelling table last couple of weekends

      - glued and dowel pinned trim on the edges, planed and sanded the edges

      - primed and finished painted both tops and also the underside of the tilting half only

    You will notice it blends in nicely with the workroom walls (I had paint left over)

    Then I worked on marking the tilt top with reference lines for the model build

      - center line

      - station lines

      - fore and aft cant line angles

    Debating whether I should mark the frame locations

    I chose to draw it rather than lay a print down as this would have been closer to how the actual build would likely have been done (in my mind anyway).

    I will spray seal it next weekend so the pencil marks stay clean and unsmudged

    Presently it is stored under a sheet of plastic to keep the dust off

    I also pulled all the nails from my second pile of eastern hemlock lathe I salvaged from my son's home.

    I now have at least twice this amount (likely more) to do my model.

    Although I continue to draw up the frames to make my templates (which a sampling of will be posted down the road) ... it looks like I'll be finally cutting some wood and starting the build tomorrow.... I cut out a few pieces from my printed template of the bow (from the gripe upwards).

    I will start by milling down some of the lathe and rubber cementing the templates to it to cut out... just like they did in the 1700's???

     

     

     

     

  4. After many hours scouring NMM collections, reviewing online books (because nothing I have here helps) and some tutoring, cyber hand holding and a gentle rap (or two) to the back of the head..... I have it.

     

    The attached is being printed today and cutting will begin very soon.

     

    PLAN_Keel + Posts layout_rev3.pdf

     

    I made sure the scarphs were located so each were over a floor timber per the contract specification.

     

    I am still working on sketching the frames at each station to be made solid, sliced up into each individual frame, 3D modelled and dropped into drawing sheets to create these templates.

     

    This will be posted at some time in the future.

  5. Are you suggesting I move the Stemson to Keelson scarph aft?

    It was one of the very few shown on the original plan.

     

    I understand the shipwright used the plan as a "guide" and followed their good judgment while keeping to the contract.

     

    I must admit making that change does look better.

     

    seems like a visit to NMM this evening is in order ... followed by a revision to my revision.  :huh:

  6. Thank you Mark ( I know, I've been following).  1:64 is definitely the smallest scale I dare attempt at this stage.

     

    On another note I have been advised my Keelson scarph joints may be located incorrectly.

     

    The contract reads that the Keelson shall be constructed of not more than 6 pieces and that the scarf joint is 5'-5" long

    It however does not say where they should be located and the Arrogant class ship at 168 feet long (stem post to stern post) is shorter than any references I have for a 74 gun 3rd rate ship of the line that show locations. I am certain the shipwrights didn't need to be told where to put them, but alas, as a Sea Cadet I was a Boatswain (Bos'n) not a Shipwright.

     

    It was suggested via PM that the Keelson joints should be half way between the Keel joints (which were shown on the ship plans) and that they should not fall under a Mast Step.

     

    I will relocate them per these guidelines and re-post.

    Thank you for the help.

  7. I practiced laying out and 3D modelling a few frames once again (re-learning what I decided I would do some time ago) and realized another mistake / misunderstanding of the contract description and so my final template will look slightly different than my earlier attempts.

     

    I will be working on these many, many profiles to make the 3d of the hull, slice it up into the frames, etc and then create the 2D template for each for cutting and building.

     

    I completed the Keel, Stem and Stern Post assembly drawing (see attached) and feel I can begin this part of my build.

    My drawing has four copies of the same detail.

       - One to remain untouched for reference

       - Two to be cut up for templates

       - and the last one as a spare copy

     

    PLAN_Keel + Posts layout.PDF

     

    I also made a visit to my son and liberated yet more lathe from his scrap pile as I read on the forum you should have twice as much wood as you calculated to cover cutting loss and scrap.  It is presently laid out flat in the basement acclimatizing.

     

    I will be practicing my scarph joinery on scraps and will not attempt it on the good pieces until I get it right.

     

    I find I'm feeling a bit excited and very nervous at the moment... first cut jitters I suppose.

  8. Ed

    I had visited your build earlier this week and made a note to come back and start at the beginning

    Came back at just before 10 am this morning and it is now approaching 4 pm

     

    Thank you

     

    I have learnt so much today

    love the pins

    love the copper wire

    love the mono filament

    love the blackening 

    love the....... everything about your build.

     

    I want to be just like you when I grow up and that is saying a lot because until now I never wanted to grow up!

  9. 1:64 in my mind will not in any way be a small model but, for me, when I hear the name Bellerophon I cannot imagine the injustice of reproducing her image in any shape less than grand.  My former crew and the alumni of #141 RCSCC Bellerophon would understand completely.

     

    I pray I am up to the task.

     

    Although I have been trying to rush through the modelling and drawing part (honestly I have, if it weren't for the side projects) the building will in no way be a race.

     

    Creating saw dust, wood chips, dull edges on knives and chisels..... I can barely wait to be in the middle of it!

     

    (I love building as much as demolition)

  10. BUILD SCALE:  it will not be 1:48 as this will be too large

    I will not be able to reach the top of the tallest mast even with my model table lowered completely

     

    I printed off three scales on two sheets ($4.25 Canadian per sheet at 36" x 60")

    Cut them out and set them on my table so I could best visualize the physical size

    Planted my measuring sticks to simulate height over the tallest mast and breadth over the longest yard

     

    1:64 will fit nicely on the table and 1:72 is the smallest I dare go.

     

    I admit to being intimidated by the smallness of some tiny components at these scales

    Scratch building will be a real test of my abilities

    I'll need a bigger scrap box.

     

    I am going with 1:64

    Decision made.

     

    I've said it before but it warrants mentioning again

    Thank you to everyone that has offered me help to this point, Lord knows I need it.

     

    I will be starting on creating my templates

    I imagine this will take some months with the amount of time I can put to this hobby every day.

  11. I believe I may have it now ...  but I do not feel any smarter

    (Thank to my ancestors I've got my good looks to fall back on   :rolleyes: )

     

    Druxey suggested running plank lines or wire frame

    My NRG mentor suggested buttock lines needed to be followed

     

    I drew in buttock lines on my frames and then drew in faux plank lines

    These showed my loft feature to be bumped out considerably on a couple places

     

    I created new 3D profile / guide lines for the pulled in shape and lofted to these

    It was still, somehow, not quite right. There were still bumps, albiet smaller ones.

     

    I needed to divide the features more and create additional lofts of smaller areas to get it to pull in better.

    post-9868-0-85644000-1420400717_thumb.jpg

     

    The pink is the old shape and the green lines are the new shape before dividing it up more

    Even after having done this all lines needed manual adjustments to blend better

     

    Following is what I ended up with.

    There are still minor deformations but at model scale and with sanding I believe these blemishes will disappear.

  12. Thank you very much for the link Lonelius.

     

    I've checked it out three times now

    I should live so long to make it look as easy as that!

     

    his post 4 image #2 really shows what I should be striving for

     

    I have a gut feeling that I am making this more difficult than it should be, that there is an easier way to complete this, if my skill levels could only miraculously multiply over night.

     

    I am using the loft command to see the outside surface of the timber /inside surface of the outer hull shape

    It seems this gentleman used the shell command and added thickness for the inner / outer hull.

  13. I did run some simulation buttock lines (like planks?) tonight and can see issues much lower and exactly in the area you questioned.

     

    I made a separate copy and was playing with it but my eyes need a rest and my mind needs to clear.

     

    Calling it quits for tonight

     

    Try fresh tomorrow. I think I need to break up the profiles more to get them to follow the right curves.

    Many many many more guide lines required (resembling a wire frame)

     

    You are much smarter than I look, and I have a ways to go to catch up to my good looks :rolleyes:

  14. heard back from my NRG mentor and my stern is not quite right

     

    looking at Gils Victory at  http://modelshipworld.com/index.php?/topic/485-hms-victory-by-gil-middleton-jotika-172/#entry8107)

    post #15 -  images 7 + 8

    They are another two very good references

     

    I believe these three lofted sections of my model are possibly wrong but before I jump into making things worse I'll be taking a break

  15. Had a busy time the last couple days.

     

    Played with the upper transom outer corner some more and have 'flattened' it about as much as I dare.

    Seems every other adjustment from there makes things worse somewhere else.

    I managed to create a 5 second animation pan viewing the corner and also a PDF of incremental snaps shots automatically generated from the animation and sent it all to my NRG mentor to comment on.

    Unfortunately I cannot seem to attach the .avi file here for the forum to view so here is the PDF.

    lower transom shaping.pdf

     

     

    I also manged (after considerable time ... it ended up being easier than I made it out to be) created a 36" x 60" sheet for my drawings in Solidworks.

    I added 2D images from the 3D model at 1:48 and 1: 72 scale to be printed out to scale on Monday so I can better visualize.

     

    HMS Bellerophon scales 1_48+72.pdf

     

    That will be when I finally get off the fence and decide once and for all on a build scale.

    I am / was (?) wanting to build 1:48 but am suddenly coming to realize the massive size this would be.

    Possibly 1:72 might be more accommodating.
