mould

I have a 36’ hull mould for sale. The mould was made in Poland and has never had a hull produced from it. It has been stored outside but the tooling gelcoat is in excellent condition. It needs a final compound and wax and it is ready to go. looking to get $50k for it. Serious inquiries only...

Hi all, I made 8 molds in the past all using wood as this was the only one that knew how to work with but is a very slow process. I now have a new design (for a 17.5 foot kayak) which has been converted to a 3D. My idea is to use a CNC to print it in foam and then make the mold from it. As I...
