This is in no way directed at you Aric or DDT but thatís f-ing lame. Iím all about bragging rights and would have been fine with that if it wasnít for the string along. From what I understand this comp brings a lot of traffic to this site and they make more money so if this is how is going to be Iím out. Iím not going to spend the time and money to do something that helps improve the site if the powers that be canít get off their asses and take care of business. Aric I can appreciate what you are up against and what you have tried to do, and thank you for trying to keep this going. Good luck to everyone that does compete.

you are right, i didn't think of it that way, i know last year I and many others checked the site multiples times per day just because of the comp. That would up ad revenue.

hmmm... with all the time and money put into mine, with no prize, maybe I'll just keep it and climb on it?
It would be hard to send this baby in for destruction without any hope of prizes.
Maybe I'll give it a quick proof test pull to make sure it doesn't disintegrate. However, I am very curious what it breaks at....


the proof of concept cam pulled out when the rock broke somewhere between 14-16 kN dynamic pull (loop of 7mm cord pulled by jeep on snow with 2:1 pulley and a redirect) , then when placed in a constriction we were able to break the 7mm loop. the cable was mangled and the lobes bent, but nothing actually broke.
The axle was undamaged........ Cool

It's too bad, I loved the competition last year from the sidelines! I understand if folks don't want to do it under the current conditions though.

Any of you guys who decide not to send things, post up some pics of your projects at least! We'll still give you kudos!

just give me $25.000 and I will give you my two new cam design secrets.

$25 K is cheap and you know it cause I have no time to go after patenting it but once I do, I will make you guys cry.

Those who know me , they know what I can do so save my time and send a check and do it now.

This offer expires in summer and after that, well

you will see

That kind of sucks, but I think I will still complete my cam and send it in just so that I can test a new method for attaching the stem to the axel. I am interested in it's strength so I'm not out anything by submitting an entry.

I'm 90% finished with mine so I'm going to finish it. Iím still putting my pull tester together but I have all the components. Iíll finish it and shoot video of the pull test, wonít be as accurate as Arics but it should be close enough.


The search and rescue guys got a kick out of using the dino to test the forces on a 2:1, 3:1, etc in the gym last week.

DONE!

Part of the reasoning to avoid entering is since they aren't offering prizes, why should I let my baby get broken so they can make more money?
Keeping it to climb with will be better than most realistic prizes for this comp.


A free body diagram of a concept I thought through but didn't build. Please excuse any mathematical errors. I was at the very beginning of my Statics book back in the fall when I did this. Feel free to steal it....

I haven't finished mine yet but here are the lobes. I spent several hours on them so you can see why I'm pissed. Maybe they should start working on it now for next year since it seems to take them a long time to get anything done.

pull testing the rough cut proof of concept cam. the axle, my main concern due to its nontraditional material, ended up unmarred after mangling the cable (no broken strands though), bending the lobes, and breaking a loop of 7mm cord on it with a jeep and a 2:1 pulley. After breaking the 7mm loop, the jeep couldn't get enough traction on snow to continue.

You should send that tree at the end in for testing. It didn't budge!

So, time is running out and I am in Red Rocks until the deadline to get the cam in. I brought stuff to finish my cam, but this morning I realized that I forgot my swaging tool, and I accidentally broke off a screw in the cam but have no tools to drill it out with. Basically I am going to be pushing it to get my cam in on time. If I can somehow get the screw drilled out today and maybe go buy and return a swaging tool, then I should be able to ship it monday to have it to you by wednesday.

If I can't get it done, I guess I'll have a good head start for next yearWink.

Ok, so my cam is done except for the swage on the cable loop. My plan is to go to Lowes or Home Depot tomorrow so I can borrow a swaging tool to crimp it in the store then to send it in to Aric USPS Priority to get it there by Wednesday. Here is a preview of the cam:

Utah Custom Hardware Extraterrestrial

-External Cam Springs allow a much more compact camming unit. With this system, Extraterrestrials fit into smaller placements and have more cam surface area per width than other units.

-Nylon trigger wire protection sheath allows true flexibility of the main cable stem AND solid cam control. Cam walk and placement change are minimized. Deeper placements are possible, but don't place the stem over sharp edges or so that permanent bending or damage will occur when the unit is weighted.

-Secure grip and control. Easy clipping and racking are provided by the cable loop. Extraterrestrials come with a sewn nylon runner.

-Axles are a .25" grade 8 steel bolt. Also. the Internal Spring system allows the axle length to be minimized, which results in a short and virtually unbendable axle.

-Cams are machined from 6061-T6 Aluminum, a grippy alloy with TEETH.

-Moderate cam angle of 16 degrees for greater holding power.

-Sturdy steel handle and top puller are crimped to 1/16" 7x7 galvanized steel trigger wire. A tubular nylon sheath provides trigger wire protection. The sheath can be taped, but don't tape tightly or it will cause drag in the operation.

-Quality connections. The main cable is individually attached 24mm deep to the aluminum cable eye fitting with a newly developed "Bonzing" process. Aluminum cable fittings are used for the swaged connections.

-Quality control. There is none, and I mean absolutely none. If you would like, I will stamp "tested" on any unit that you would like.

-This cam is rated to 46 kN but my guess is that it will fail at around 6kN by mode of the cable pulling from the head.

Here are some pics

Picture 1

Picture 2

Picture 3

Picture 4


edit because my post doesn't seem to be working.

still not working and I can't figure out why

couldn't get the pics to work, so here are links.

There are no springs on the axle, they are just the visible springs below the lobes. The action feels pretty smooth, but the wires that move the cam lobes are a little bit soft so I should use something stiffer in the future.

I ended up swaging the loop in the hardware isle of home depot, I just tracked it and it is at the post office in Aric's home town scheduled for delivery today, so I think it made it!
