This sounds fun. If I can get some access to my school's machine shop over break I may give it a try.

I'm in. Can we get a rough idea of the date?
What about holding 5kn being a litmus test and having separate catagories for highest strength to weight, most innovative and the beauty pageant?
Should cannibalized cam parts be allowed?

adatesman wrote: Hey Ryan, Up thread a bit I think we were kicking around an entry deadline of end of February or something like that to give everyone time after the holiday craziness to build their entries. A definite date hasn't been set yet though, as I haven't settled on a set of rules and Our Mostly Benevolent Blue Overlord is looking to secure a sponsor and prizes. As for the rest, that's exactly the sort of thing I'm looking to get in this thread.... How do you all want to structure the competition? The rules above are just what I came up with and I have no problem changing them around a bit (or a lot) if someone else has a better idea. Plus the sponsor might want to change a thing or two, so these rules are by no means carved in stone. I don't know if we'll get terribly many entries, so I don't know how well awards for individual criteria will work (hence the weighted composite scoring above). Personally, I don't mind cannibalized parts but I'd probably want to see a bit of a penalty for doing so beyond a certain point. For my prototypes I use RE Durangos, but RE Comets and CCH Aliens also disassemble easily. FWIW, the spec cam I'll be providing instructions for will be entirely DIY with parts mostly from McMaster-Carr. EDIT- Oh, I should probably point out that I've dropped the target size that we batted around a bit earlier since scoring based on expansion ratio takes care of the issue I was worried about with giant nuts. so feel free to do anything up to ~6.5" expanded size, if you are so inclined. The spec cam instructions will probably be for something ~2" expanded, depending on how the cost works out for the materials.
What if there was an all wood category for us without access to a metal shop?

Hey John, Well, if there's enough interest we certainly could do a non-metal category (might as well include composites...). But you don't really need a metal shop to do this.... The only tools used in the instructions I'm working on are a drill, a nail, a hacksaw, a file, a pair of pliers and a screwdriver.
I have all of that, but It's going to be tough deciding between metal and glossy stained wood.

If I get addicted to building cams I am blaming you.

I am still trying to decide if I want to put in the effort and get in on this. Will entries from canada be accepted?
My two cents on the proposed scoring:
It seems to me that the Max Strength and Strength/weight ratio scores should be capped at some maximum. At a certain point more strength is just not necessary for climbing purposes.
Similarly, strength to weight ratio would favour very small cams. When you seemed to want a size neutral scoring. A very small steel cam would score well. A better metric might be the maximum-size/weight ratio of the cam. IMHO
(edited for spelling)
