: I am currently working on a similar project with a couple of guys. We made
: our male plug from foam and plaster, which is a tremendous amount of work.
: We continuously add plaster, fair, add plaster, fair and so on. Our plug
: is almost finished now, and we expect to be laying up our 2 part female
: mold in a few weeks. Our layup is going to consist of wax, wax, PVA, PVA,
: Gelcoat, Gelcoat, Fiberglass mat, 6oz glass, 6 oz glass, 18 oz roving, 1/2
: inch plywood frames. I'm linking a pic of our plug in its current state.

From the look of the male plug you are putting the effort into making the male plug the finished surface. I will have to do a fair bit of sanding and filling on my existing shell to get it even close to that. I am sure that is easier then trying to fix the female mold once it is done.

When you say two part mold, you are planning on doing each side separately? The Giak was done as a top and bottom, but it will take some effort to separate mine as the patches did not avoid the seam. And the screws every 6 inches are completely rusted. I hate to start, as once I do I am committed and can't go paddling until I finish.

I look forward to seeing your pictures of your continued progress. Thanks for sharing.
