Whats up your arse, doughboy? you have your opinion, I have mine. Theres no need to get all worked up about it and get personal. My question is factual and it would help me a lot if someone actually knew the answer.

Hey Vinman, I completely missed the point that RL is measured when ski is flat. My calculations are actually based on that assumption and yes, RL and effective edge should be very similar. Yet, if you look at manufacturer's quoted RL and effective edge, there is a significant difference... This is w...

Rocker - maybe. Magnetraction just slows you down, but we are going off topic...

There has to be someone from the industry on the website who knows the difference in derivation of effective edge and running length...

to doughboy: nope, you are talking running length. Effective edge is longer than running length. I am looking for a conversion to enable meaningful comparisons among different brand geometries.

to montuckymadman: you may have a point, but it is quite irrelevant to my question.

Good point. I think my question is as much about definition as it is about maths behind effective edge calculation. My logic stems from effective edge definitions found on the web, but obviously I am missing something..

hey webboy... I am just looking for a simple circular symmetrical sidecut formula. From my experience, all these progressive sidecuts and stuff dont make much difference for an average rider.

sure, follows both. Effective edge is what contacts the snow when you are turning...

You are talking about effective edge. Running length is the distance along the ski length between the contact points. In a traditional ski its the distance between the widest part of the tip and the widest part of the tail.

anticipating some conversion factor discussion, there are a few floating around. such as 0.88 for skis and 0.96 for snowboards. However, I found these rules of thumb to be very unreliable...

Hey crew, Been pondering on how to convert effective edge data to running length and vise versa. The way I thought it should work is running length is basically the length of the segment of the circle used to derive the sidecut. In which case we get the sidecut radius and the running length, estimat...

Hey Madman,

Thanks for the explanation and the vid. It is actually clear enough. So I will look at silicone then. In terms of molding question, I meant that do I need to make a cambered mold, or would a flat one be good enough. In the end the press should press it to camber. I hope...

yeah, SnoCad is based on vertices. If you go to tools, you can actually choose your vertex density. My laser cutting guys cannot use direct DXF exports, their machine stops every millisecond and shakes and rattles the workpiece. I tried converting the polylines to curves in CorelDraw, and it does a ...

Thanks MontuckyMadman,

If you dont mind, I will pick you brain a little. To make a urethane mold, can I just use a laser cut template, or do I need to use a shaped ski?

Hey guys, I have been looking at the forum for a while now. One question still bugs me and I cannot find an answer. Going back to twizzstyle's post, does enyone know how exactly a cap cassette like WhiteCrystal guys are using would work in a press? I mean, if it is rubber, how would it exert pressur...
