  1. Hi Druxey, Thanks, I have come to basically the same conclusion. I am also guessing that this boat was built over forms with stringers then frames bent to the stingers and then planks to the frames and the stringers removed as the planking proceeded. funnily enough that was my first planned way to build this model.

  2. Here is another picture of the bow from inside the boathouse.

    I think that one of my problems has been with the placement of station lines and the conjectured placement of the frames at the bow. and thinking that these are one and the same.

    I have been trying to reconcile a frame at position 1 and am beginning to think that I have this all wrong it makes more sense that the first frame would be at the place I have marked as 2 in this plan view

  3. Hi Mark I think I understand what you are saying here is a different picture and the information that Roger gave me way back in the year 2014

    a - 3 3/8

    b - 3 inches deep x2 1/8th at the bow 2 inches x 1 3/8 at the stern 

    c- 31 inches at the bow

      - 38 inches at center

      - 15 inches at stern

    d- 3 inches at bow

      - 5 1/4 at midship

    `

    There are ten planks

     

    All the other dimensions that I have are taken from inside the cockpit ie length of open cockpit width of cockpit height of coaming ,seats etc

    Visualize the rabbet as the outside shape of the boat, but less the planking.

    Initially I thought I was on this track, I think  that I made the whole keel too small on the vertical size, also I drew the keel as a rectangular section. I am thinking that this was an error. The keel is basically rectangular but not the whole keel the forward portion is most likely shaped to conform to the lines of the hull to create a smooth transition from the Stem to the keel for at least a few stations and gradually transitioning to the more rectangular section.

    I have redrawn station 2 to correspond to this notion.

    168536307_STATION2.thumb.jpg.b7bc81b75fca3deef6de0de342ef876f.jpg

     

    And in this close up of the keel area the right side of the drawing shows the rectangular keel as made in red with the newer profile mirrored on the right. I am guessing that the planking was thinned down to around 1/2 inch as it meets the stem at the keel. It would look quite chunky if it remained 3/4 which is what the thickness of the yellow Cedar is. The magenta line shows the taller keel section with a height of 4 3/4 by max width of 1 3/4.

    Why am I getting this feeling that I need to start over,,,,,,,sigh!

  5. There is nothing like doing a bit O' wood butcherin' to begin to understand the way things work as opposed to how one thinks they are supposed to work.

     

    Trying to really understand the interface between the keel and the Garboard strake. I twisted up a bit of 3/32nd yellow cedar  and the plank certainly needed to be thinned a bit at the bow. This is just a basic test to see how the two parts mate and how to cut the rabbet which turned out to be completely different  than what I had drawn. The garboard is just sitting there gravity holding in place.

    Now I understand it a little better.

  6. Did not do too much today just a bit of refining of the keel drawing and gluing the top part of the keel to the lower I used a darkened PVA glue in order to see the glue joint as I shape it.

     

    IMG_2374x1024.jpg.6cc0b53f7aa5826ac5cee29fd01ae853.jpg

     

    Also rough cut 22 sheets of Yellow Cedar for the planking. There are 11 planks each side. The planks were 3/4 inch thick which makes them 3/32 thick for the model. I used the jointer to plane the edge each time next to the fence.

  7. Today was another one of those aha moments when I realized that the top plate of the keel was not drawn correctly, You Know this model shipbuilding from scratch is not for the feint of heart is it! I picked up some printable card stock to cut yet more test templates to see how the frames and keel and planking all intersect at the keel.

    This was the Aha moment.

    21749764_testtemplates.thumb.jpg.3d7af6746d2dfe51153b4ffcc1967e29.jpg

     

    The red line is the outside of the planking , the two black lines represent the frames and the blue represent the top layer of the keel. These test templates match up with station lines 2 ,5,14, and 22. Also the two positions of the floor of the open cockpit are shown as the horizontal lines and how the interface with the frames at #5 and #14 which is where the floor steps up around the engine. I am really hoping that this all comes together as a model that looks like the real boat!

    From the side the space is clear that I now need to add the top part of the keel which is much narrower that I had originally envisioned.

     

    That enough for today.

  8. I am so glad that my little model shop is air conditioned, it was 31C here today and anything above 20-22C I find uncomfortable.

     

    Finished rough shaping the stem today so now I can concentrate on the frames and floors.

    I am quite happy with it

    Her is a comparison between the first keel and stern and the new one, Although I do like the overall shape of the first Perhaps I can build a freelance model on it at some later date or lifetime.😉

  9. Worked on a bit of carving the stern today. first I set up to add the (bronze drift bolts) brass .046" dowels these were angled differently from each other, similar to a dovetail

    Then using riflers to rough shape, along with some careful #11 exacto work the stern is done far enough for the moment.

    Tomorrow the stem.

    And as an aside I was able to book my second Covid Vaccine for Friday the 5th June, this afternoon, when I logged onto the AHS site there were only 21,000 ahead of me with a wait time of 26 minutes till it was my turn to book.

  10. Thank you all for the visit and appreciation.

    The vast amount of Sanding was an overstatement to be clear. It turned out to be far less work than anticipated.

    After checking that the shape was in the ball park. I worked on tapering the fore and aft portions of the keel ready for the stem and stern timbers.

     

    IMG_2298x1024.jpg.20a5e08169f66cb304ea811a25e7adad.jpg

     

    Some thicker blocks were roughed out to profiles and glued to the keel tomorrow when the glue has properly set I will add some 1/16th dowels to reinforce the joints before shaping them.

    I'd be happy to show my work, but many of them are not sailboats, for fear of violating forum rules.

    Thank you for you kind words. There is a place on this forum for showing other work that is not ship related like this post

    I also enjoy other forms of model work,so there is a place for you to show us you other work.

  12. So the last couple of days have been part of my usual dance one step forward three back, I call it "the shipbuilder's waltz" 

    Basically what I realized was that with some of the changes to the lines and the body lines and plan needed to be redrawn accurately for the subtraction of the thickness of the ribs and planks. Unlike Druxey I did not have the confidence to set in the frames or ribs into the form and I also needed to refine it a little here and there.

     

    Lots of work redoing sets of templates because now it is all of a block. here are the results, of the drawing.

    Tomorrow feels like a big sanding day.
