about how much does it cost to get a mold CNC'd? and a core?

buy a lot of 1/2"x1/2" square aluminum tubing and string it all together

try a local scrapmetal place, they can be really cheap

is it 8 inches inflated or deflated?

it depends on what side you put it on. If you put it on the top, it will give it less camber. If you put it on the bottom, it will give you more camber. Think of the heat pad pushing away the ski from wherever it is.

the problem with that system is that it has a 7 day cure cycle, opposed to CPM's 20 minutes. CPM is also a little stronger

well that definitely makes things easier

doughboy I would normally agree with you, but the search function on this website is almost useless, so it's kind of hard to find the information you want

I think Jamewstown is just an online supplier, and they don´t have the cmp resin, I´m not sure how good the other ones are

that could make a cool base, unless it becomes a mucky brown/black color

I mean I live fairly close to you so I would be down, but I won't be available to do anything until late June, if you want to wait that long

should I just make my top mold as tightly fitting as possible?

can you attach it to a wood template then use a router?

how do you get the ends properly pressed if you have a tip to tail core, without using rams?

I would only use heat curing epoxies. Non heat-cured epoxies are like 1/3 as strong as heat cured.
