Best mold sheet to use?
Just made some mold ribs today, to save some time and mdf I want to use a sheet of either plastic or metal. But I do not want to use any thing to thick that will alter the shape of the ski profile.
What have you guys found that is thin and will not compress down with a gap of .25" to .5"?

3/16 Masonite at least. If it is only ribs with spaces in between you need something to make a nice smooth base or else risk some press thru from the ribs.

How are you guys attaching the masonite to the mold?
My molds are full width MDF ribs, but I am thinking it would be good to cover these with a thin sheet of masonite 0r maybe plywood. My idea is to cover it and the ribs with a thin coat of epoxy and then press it on and cure. Any good? (bit worried about what happens to the epoxy every time it heats up again during a real pressing)
Otherwise screws?

Used to use MDF too between the tip molds and also over the "main mold" ribs to have a smooth surface...
Found out MDF used horizontally + pressure + heat = MDF compresses, see one of my last topics for more details. Since then I removed the MDF sheet over the "main mold" ribs and switched to Plywood for the sheet between tip molds... still have to check overtime how it's going...

Just use a softer, like 5053 .063 aluminum. Seriously. Coat the aluminum with mold release,counter sink your screws along the outer 2 ribs, route a channel in the form under the aluminum sheet for your heat blankets and be done with it. It's the way everyone does it...unless you just want to get weird about it for no reason.
