Default Bracket finally glassed!

It took a lot of time to measure and cut all the Matt and Biax and way longer to lay it on.
And of course had to cleanup mold and hairspray/PVA it again.

Three layers of Matt and three of Biax, but with the overlaps, some areas, esp. the corners, have 6-9 layers.
7 gallons of epoxy including the thickened putty for the transom.

Finally with no rain, started the layup Sat. afternoon, continued through the night and got all the way up to installing the core and it didn't fit!
All the layers of of cloth had made the space too narrow and trying to wedge it in, I screwed up some of the cloth in the corners.

Since it was 3:00 am, I didn't break out the grinder, but tried to hand file it; after half hour of that, gave up, cleaned up, and got to bed at 4:30.

Next day checked it out; looks like I'll have to grind and repair in the corners, but overall the tub looks good.
The transom has a nice layer of thickened epoxy and fibers that I'll have to grind flat to attach the core, but at least it won't be so messy.

My concerns are I have some white areas; small bubbles in the last layer of Biax, mostly in the hull forward of the tub; it looks solid underneath. I'll fill in the small holes with epoxy and grind the larger ones out and glass them.

There are some bigger areas, between the strakes and going up the sides, that I'll also grind out and lay Biax.
The sides really stiffened up with the extra glass, so I can imagine how the rest of the hull is now.

Also I'll be tying more glass when I add the stringers, sole, and core the sides, so there's going to be even more overlaps.

Oh yeah, had to cut some epoxy off my armpits and head!

It didn't seem like a big job until I got into it!
Probably been a lot easier to enclose the transom and mold a separate tub, but hopefully everything else will be easier from here on.
