Where'd Majid's post go? I'll pay money to see him take a whipper on one of his homemade cams, and I bet there are a lot of other RC.com posters who would as well.

I'd gleefully pay for footage of him taking a 150' factor 2 whipper onto a slung can of denty moore beef stew. Btw rad contest concept from the OP. Just might have to come up with an entry myself. Would help if the deadline was extended to say Feb. tho. Things are kinda hectic now.

I might be in.

Let me mull a crazy idea around for a while.

A couple hints, it would lose the because of it's weight and would be so specialized as to be nearly useless. If I make a nearly useless cam, I might call it the majid special.

February? Sounds fine to me... I had picked the end of the year rather arbitrarily, figuring it would be far enough out to give people time to do it yet soon enough to not lose interest. I forgot about people generally being busy around the holidays, so pushing it back is probably a good idea.

Thinking about it some more, I think that having a predetermined crack size may bias the strength testing towards designs with high strength and no range. To account for this the crack will be set to a random width of somewhere between 1.5" and 1.625" for the strength test. That should weed out non-adjustable miniature Big Bros and ginormous ballnuts and make designing in at least a bit of expansion range necessary.

Thoughts?

I think this is an excellent idea. If it's successful it'd be super-sweet to make it an annual thing and get the gear manufacturers to sponsor. If you want to go ahead and formalize the contest rules and grading system and post up here, I'm almost certain to enter (especially if there's a beauty pageant category).

Yeah, seriously, we never did get those pics of him on a bivy twenty feet up. I feel like I was totally led on. Mad

Upon further mulling, I'm in.

Actually I'm out.

I'll introduce a piece that will make some wild and wierd aid pitches go by really fast. Almost certainly A5, but fucking quick and easy. It's going to be so different than the competition that it won't be able to be scored. It will have some cam lobes though.

I might even try to use it, though I'm kinda scared of it.

I don't post much, but I want to play too. Put me in for two, one crafted by hand, and one with CNC'd lobes and other parts, the CNC time will cost me some beer, but it's worth it.

Option 1 gets us going sooner, but Option 2 has awesome prizes. I assume everyone would prefer Option 2?

Somebody thinks he has a winner in mind!

Nobody's questioned this yet, but for what it's worth, even with a sponsor, adatesman would determine the rules with Lab input. A sponsor would just get their name and logo in on it in exchange for prizes. If somebody came up with something really special, that sponsor would have no unique dibs on it or anything, so don't worry about that either.

Is the sponsorship to pay for the prize or is it to pay for the cost in prototyping?

Also, is there an "atypical" category.

What I have in mind is very much a camming device. It is not however what would be considered a cam (friends, camalots, spring loaded thingies that go into cracks). To my knowledge, it's never been seen before.

The mockup will be made from wood and owing to it's design will be both weaker and heavier than most of the entries. I do expect it to be capable of it's intended purpose. Scary aid. The thing is not designed to go into a crack though so it's hard to score against the others.

In this case, it's to get good prizes. They'd get their name involved in exchange. Even if I can't get a sponsor, the site'll cough up for some sort of prize... even if I have to pay for it out of pocket. But, a sponsor = a better prize. Wink

The rest of that's above my pay grade, though needless to say, I'm pretty freaking curious. Maybe you guys need a winner for strongest and most creative. adatesman has the final word on that.

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?

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.

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)
