I find it hard to believe that a properly waxed ski is slower than an unwaxed ski. Im sure most major ski manufacturers that supply skis to world cup racers have explored this area and if they thought a racer could go faster and win on their skis by not waxing them, then racers would not wax their s...

You may have an old link to the forum. When they updated their forum a few months ago, the path changed so older links wont work.

I do this with my cores. I notice less initial relaxation in the camber and so far my boards seem to hold their camber better over time than the ones where I didn't pre-bend the cores.

I think McMaster-Carr has black UHMW-PE bars

I just got in some edges that CDW bent for me. They came out pretty nice and were not too expensive. The only catch is that I had to by 30 pieces. Im looking to have my edges pre-bent in the future. What kind of information did you have to provide for them to bend the edges - just a cad or .dxf fil...

I have to agree with G-man. A flat vacuum hold down table works great. If your cnc router lacks z-axis travel you could just tip your whole vac table under the cnc router.

McMasters does carry UHMWPE bars that should work.

Powdercow, I think the reason there is not a standard flex measurement is that it is too complicated to translate the data into a purely quantitative useful number. While I think your method of using multiple weights to explore the skis deflection is better than a single weight there are still a few...

I'm pressing at room temp with that material right now.

I have been using this http://www.pro-tect.com/catalog/index.php?cPath=40 for my top sheets but it it doesn't stick especially well to the bases. I dont know how it handle a heated press. Regarding the bases, has anyone tried applying a coat of ski wax (like a base prep wax) to the base prior to pre...

... I am wondering where other builders are getting the top sheet material with the protective surface film already attached?? I've talked with 3M and they don't seem to have any knowledge of a surface film that would work for this. Seems odd that they don't, but maybe I just haven't talked to the ...

You probably need to find a copy of the "Manual of Steel Construction" by AISC. I dont think they publish the beam tables on the web because they want people to buy their book but you might be able to find a hard copy at a library. If you have calculated the moment of inertia (I) that you ...

W8x18 beam is 8" tall by 5.25" wide. The 18 is its weight per foot - 18lbs per foot.

Collin is correct that an oxy-acetylene torch is the way to go. The cuts should take less than 30 second each.
