Transom inside done-finally!

Added 1708 pieces between the taped edges.

And filet and 1708 tape on the corners of the hull and covered that with another 1708 layer to get to about 1/4" thickness in the middle of the panels.

Then glassed the inside of the transom- layers of 1708/1700/1700/ with a final layer of 1708 over everything- this layer was a pain, besides being unwieldy to layout, the glass gooped up in places and the rollers that I applied the epoxy with started to break off. At least the white spots are bunched up mat and fibers now, rather than air pockets.
It looks crappy, but it's solid!

The outsides of the corners came out mostly smooth; very little fairing. Leaving the transom piece on until the stringers are done.

Mold off!

Decided to remove rest of mold, since I was concerned with undersides.
Overall looks good, panels are flat, and strakes are straight. Some white areas to repair but looks like I won't have to sand/fair as much as I thought.
It looks like the glass edges at the transom is about 3/4" thick!

If I had to do this again, I'd use plywood melamine so moisture wouldn't distort it, thicker panels for the bottom to help keep the shape, and make the tub sides out of one larger piece, instead of the two pieces I used, so seam would be cleaner.

This is so cool to watch.

Been awhile.
Glassed the transom top, filled in the bolt holes, and most of the grinding. Tub came out good; a bit more sanding underneath.

Made the forms to raise the stringers.

Poured the foam.
Will cut out for the rigging and drain tubes.
Then lots of glassing!

Stringers done.
Filleted, tabbed, couple layers 1708, and lots of epoxy.

Keelson removed.
Going to replace with about 6" wide composite board; will act as drain for fish boxes and subfloor for fuel tank.

Next lots of my favorite thing- grinding and sanding.

Do yourself a HUGE favor. Sandblast instead of grind. Way faster and easier. Harbor freight stuff is fine. You will use a lot of sand but be super happy with the result. Getting in corners is easy that way.

Thanks, but I just spent last four hours grinding and sanding; went quickly with 36 grit grinding wheel and 60 grit sandpaper. Did the stringers and mostly between them to prepare for glassing.
Lots of dust but had the full suit, pullover hood, respirator, goggles, and gloves on. What I hate most about grinding is putting on all that gear and the dust and smell. And usually the heat, but at least it's February now and not August! My usual attire is flip-flops, shorts, and T shirt.

Removed the bow eye (had to use a torch) and I'm glad I did; the wood backing plate was rotted.
With the raised sole, I have to raise the bow eye too.
The bow eye is the very last original part of the old boat, other than the hull.
Also ground out a few large globs of putty/glass fibers, with voids underneath; will fill them in and glass over.

Keelson is now gone!
