My dumbbells served another purpose.
The woven roving has been laid and the ground plate in place. I read how Glen Maxwell used a vacuum bag to accomplish this in the file section of the Paradox Yahoo Group. However, I didn't have the equipment to do it that way, so I used what I had... lots of weight.
First, I drilled holes around the perimeter of the copper flashing, then counter-sunk them. The epoxy oozed up through the holes and then acted as rivets to help hold the flashing in place. To hold the flashing flat while the epoxy cured, I placed a scrap of 5 mm plywood on top and then added lots of weight to hold it against the hull.
The bottom is almost ready for the paint. I'm thinking navy. That's next on my to-do list, buy the paint. I'm hoping she will be right-side up soon, and then never again up-side down.
