Interwebz help: edge bender thread
Tried searching but I can't find a thread about making an edge bending out of a cheap tubing bender like this one: http://www.homedepot.com/catalog/productImages/300/e1/e1a131fa-9ad1-4459-8894-433b87724739_300.jpg I swear I've seen something like this before, but perhaps I'm going insane. Little hel...

The following comment is entirely opinion without all that much real knowledge, but I gotta believe that on some level, the prepreg stuff from DPS is marketing. Now, I didn't say marketing BS. I buy the opitimum resin ratio blah blah, but I also figure that if the carbon manufacturer can get the rig...

http://farm5.static.flickr.com/4059/4567028461_56ebd4c93f_o.jpg PID control box. Finished wiring. Made a few idiot proofing labels. Now need to decipher the algorithms to program the heating profile. Man, those labels are seriously askew. I don't know how well your skis are going to turn out. :D In...

AFAIK, thermocouple type (J, K, etc) refers to the metals used in the TC and not the shape. Your TC reader may or may not be able to read more that one type. I don't know if the TC will leave an indentation or not, but I don't see a huge problem with putting it on the top side of the heat blanket an...

I still think that yes, if you have a carbon fiber beam and a fiberglass beam of the same stiffness, they will rebound the same. I could still be missing something though... [physics geek] Almost, for a spring, F = -kx where k is the spring constant (i.e. stiffness) and x is the displacement. So th...

Thanks for the reply. I guess I should've reworded at least the title. I was referring more to methodology for designing the mounting point rather than finding it on an existing ski. The chord center method has nothing to do with the sidecut of the ski. I'm guessing it works out because most skis ar...

How far back for mounting point
So, If I go into the how to section, it suggests making a single arc. If the tips are wider than the tails, the narrowest point (and hence mounting point? -- correct me please if I'm sorely mistaken) would be back of center. If the tips and tails are the same width, the narrowest point is exactly on...

Vacuum bagging at altitude?
Howdy, Just ran across this site about a week ago. Before finding it, I had thought about building my own skis from time to time (I build my own bike frames), but I didn't think I had the background in skiing to know how to design a ski layup when it came to # of layers of fiberglass, core thickenss...
