I made the mahogany Plugs from scrap and glued them in with epoxy.
Next, I had to make templates for each of the 4 corners in the cabin areas and transfer each curve onto its own form. I then used the forms to glue up 3 pieces of 1/16" material. I let the glue-up dry overnight and then trimmed and epoxy each piece into place. I was only able to do two corners at a time because I ran out of clamps.
I had to get creative with the clamps for the corners
The above photo shows one corner glued in using epoxy.
