My concern with having no topsheet above the epoxy would be that epoxy is not really uv reistant at all. It will break down and virtually disappear with a lot of exposure to the sun. We had a few wooden canoe gunnels we coated in epoxy but never got around to varnishing and within a year of being ou...

with gregs method you could mark 3 points of the curve...either end and the midpoint then bend to those 3 marks and that would give you a more consistent...known...curve.

We might be interested in getting some....if you can find them.

maybe it's overkill to go with more pressure than that...I don't really know what kinda pressure is needed cause this is our first attempt at making skis. We just figured we wanted to make it able withstand 100psi so we could experiment with different pressures.

Thanks for letting us know. I've been meaning to do some analysis on it but hadn't got around to it. I think we're gonna try and find some more steel for that bottom section. If we're going to make a press that big and heavy we want it to be able to withstand a lot of pressure.

We would love to have everything be unifrom but were working with free steel we got here at school and what we got is what we find. I like the idea of tying the top two beams together to try and even things out. The T's we we're planning on making from one big ibeam 16x7X.5 making them 8X7X.5 or abo...

I just drew up our press design in proe. I think it should be pretty solid. Our biggest concern is that the two ibeams on top are a slightly different thicknesses the one is .25" the other .375" so the one might difflect differently and cause uneven pressure. What do guys think? http://arc...
