The mold itself took almost three weeks to build, the third attempt is the one that worked. I tried the two different way to prevent having to drill holes in the hull, it didn’t work. Daytrip1 from a few different boards has done two, and I copied his first build.

It work perfectly! Once I got the Mold correct I put 3 layers of PVA on it and started the layer up. I was shooting for 1/4 inch of thickness, so I figured that 7 layers of 1708 would match the hull. All the layers werehot coated and each layer was rotated 45 degrees of each other to and strength. After an 8 hours and 5 gallons resin I ended up with about 7/16 think glass! All sides of the bracket are close in thickness with the corners getting extra layers. On to the clamping board coring. This was SO easy without the curve of the transom to fight with. Used thickened resin to glue and screw three 3/4 marine plywood over night, then glued and clamped it in the bracket.

Really the only thing to note on these ones is the stringer extension holes cut. This was challenging, trying to make the holes long up perfect with the internal stringers? Lots of pilot holes and still was like 3/4 inch off on on.

Ok this is outcome after the mold came off.

Pictures of the stringer extensions from the hull to the bracket.

Looking good. :clap:

Just more pics but it’s out of the garage.

It’s been too long for an update
 

Well I haven’t updated this for a long time but work hasn’t stopped. I spent the whole winter picking away at the bottom. It was crazy there had to be close to 1/8 inch plus of bottom paint!! I ended up flipping the boat and just sanding forever! Once I got it all off I spent a ton of time trying to fair what I could it’s not perfect at all, but it will pass the “good from a far but far from good” test.
I’ll add some pictures tonight of the progress. Hope all are health and safe!

These are from November, just never posted them.
Used my redneck gantry crane to flip it.

Admit it, who is this?

Once it was over I glassed the bottom of the bracket to the transom.

So after months of chipping away I was happy with the bottom. I rolled 4 coats of totalboat total protect high build epoxy barrier coat. Then it was time to spray the finish bottom paint on. I went with Interlux VC performance epoxy. Great stuff to work with, easy to use and came out looking good. I had a few spots I messed up on, but over all I’m really happy.
