Still slow going. I took the old transom core and used it for a template to make the new transom.
It will consist of 2-3/4 inch pieces or marine ply. I'm using vinyl ester on this project mostly because the price of epoxy has increased dramatically since doing my last project. I Put down a layer of 1708 on the inside of the cleaned out transom and let it get tacky. Next I moved over to the the new core and put a layer of 1708 on one of the two transom cores. I smeared a good ammount of vinylester mixed with milled glass fibers and cabosil over the surface and layed the other 3/4 inch core on top of the first.
This should provide a good bond between the two. I put a some 1- 1/2 inch screws in the core to get it to suck together.
I had to cut a bevel in the new core to get it to sit in as close to the edge of the corners of the transom as possible.
Here it is ready to be installed.
The 1708 that I layed on the inside skin of the transom was still tacky which is what I wanted so I then smeared a good amount of vinylester/cabosil/milled fibers paste over that
and I also made a bed of this paste around the sides and bottom of the transom for the new core to sit into.
To get the new core to bind tightly with the outer skin I used 2x4's and long carriage bolts to suck it all together. The plastic sandwich wrap will prevent the 2x4 from sticking
to the sealed core.
Here is my sandwich job. It's nice and straight. I'll let it set up and cure before I finish the inside of the transom.
Next I cut some foam to extend the stringers back
It was kind of a pain getting them to fit right . I had to do a lot of cutting and rasping. But they fit OK. Nothing fancy here. They will get cabosiled in place and glassed over.
Thats it for now.
