i have finished with building frames and now ready to move on to the keel assembly.
Mast and Capstan Steps
The design for the steps was based on the Canadian replica. A straightforward design that is working. I used magnets to assemble the steps the main mast has a pair of knees reinforcing the sides of the step the other steps are not reinforced. I drilled 1/8” diameter holes in the steps to set the masts, not historically accurate but works for the model. Progress photos.
before moving on to the keel Mike gave me a good idea about magnets. This is how i started assembling frames by pinning the parts in place.
then i thought of a piece of sheet steel and Neodymium magnets (rare earth magnets)
these magnets are so strong they hold the pieces tight in place, I tried both ways by putting magnets on the piece and lined them up with the drawing. You can actually flip the sheet upside down and wave it in the air and those parts are stuck in place. You can not pull two magnets apart , you have to carefully slide them apart.
What makes the build so accurate is because the parts are cut exactly to the drawings. As long as you build the frame to the drawings everything should come together. I hope
I did scrap 7 frames by gluing them together wrong so i had to scroll saw new parts out and sand them to the shape of the drawing. As long as you take your time and shape the parts to the drawing you can't wander that far off the build.
setting up the keel i am placing the magnets along the drawing to wedge the parts in place. To adjust the joinery i need to lift the piece out and then place it back in the exact same spot. A tricky job setting up a jig with rare earth magnets, they just don't attract to each other, they slam themselves together.
