glass, the inner coaming was added to give a little more stiffness. We
decided to apply the coaming in 2 thinner layers, added the second
layer after the sides were attached. Took a bit of filing and scarph
in place to fit the nothches. The inner coaming is Philipine Mahogany
and was too hard to bend otherwise.

fantastic job drawing it as it actually fits. Once lined up, a few
temporary screws and glue and fillet. Easy as long as there are 2
people working at aligning and holding in place.

adds more epoxy to bury the cloth, self levels pretty well. Not
perfect but better than if we had waited until it was upright. Less
epoxy wasted dripping down.

Chine logs. We used 2 layers of 3/4 by 2 1/2 and 3/4 by 1 and
something with the angles precut. We put them on one at a time. Shaped
the top with a 1 inch roundover bit, belt sander and hand block. They
came out pretty well.

The nails hold very well, don't have the shear strength of metal
nails, but they don't damage planes/saw blades and can be sanded. We
screwed the first layer of the bottom and used mostly the polymer
nails with a few screws on the second layer, glass right over them.
They are good to tack scarphs so they don't slip before you get a
clamp on them.

wrapped very well around the chine logs. Got one other coat of epoxy
on, now we have to wait until our next epoxy shipment arrives. Have
used 3 1/2 gallons to this point with very little waste. Have never
used more than a gallon on any boat we have built in the past.
Have a happy and a safe July 4th to all.
