Got the bulkhead in today. I have some resin burns from where it snuck around my moon suit when I was tabbing it in.
I have about 4 layers of 17 oz biax tabbing by the keelson. It is hard to get good wrap over the keelson, so there were a lot of smaller pieces. The balance got a layer of 1708 DBM and a layer of biax. Scantling rules call for a minimum of 22 oz, so that is covered.
I was running out of light and my lantern died. It looked good until I hit it with peel ply. At which point it wanted to stick to my gloves more than wet cloth. We will see if anything lifted.
The bulkhead is ~1" thick. A 3/4" core and just under 1/8" skins. It is far stiffer than 1" ply. And light, too.
I am *SO* glad to be done with under deck work.
The deck stiffener was a lot easier to trim than the bulkhead. I actually destroyed a carbide 5-1/2" blade. Not sure how, but it lost all the teeth. Thankfully there was a spare kicking around.
