sweet, I won!!!!! I can't wait to collect my prize, oh wait, there is no prize this year. Well whatever, I still want to see how strong it ends up being.

I wanted to try out a new method for connecting the axle to the cable. I thought up a new way to bond the cable eye to the cable. I think my method should be fairly high strength so I am interested in finding out how strong it is. I am calling it "bonzing" since I bonded it using the principals of how brazing works.

Well anyway, thanks for your support Aric even if you didn't get any support from anyone else.

If we are going to be betting on strength this year, my vote is 6.3 kN by mode of the cable pulling out of the cable eye.

Adatesman,

I know I missed the deadline for this years comp. However I was wondering if you would still pull test my cam for me? I really want to compete next year and a test will let me know what is working and what is not. I really like the axle and the way it is put together minus the stem. I used SS tubing due to not having cable, swages or the know how to properly crimp them (force). This is something I will just need to learn, test and execute. It is not complete the trigger wires and springs will not be on it due to I don't want to disclose my setup. But as of now it is ready to be broken. I am willing to pay you for this I don't have much money but can trade, biners, chain, webbing, rope, pitons, whatever you need. Let me know.

Thanks,

Dustin

Huh? I think you vastly overestimate my abilities...

The current scarcity of them is likely due to production having halted temporarily because of Dave's passing. Nadia has said they should be back on the shelves again sometime this Spring, and I seem to recall reading on ST the other day that a shipment had just arrived at the Mountain Shop in Yos.

I think you vastly overestimate my abilities to accuse you of something.
I was saying that cam that was entered in the contest was an Alien killer.

Oops! Blush

Sorry, I tend to get twitchy any time someone mentions Aliens. Crazy

It is ok. Do you have trouble sleeping?

That I do, that I do... Laugh

On a more serious note, Kennoyce isn't the only one who's been working on an Alien Killer... I've got one in the works too and it's looking quite promising (read: the prototypes work perfectly). I'm hoping to have final versions ready for beta testing and shopping around to gear companies mid-summer, but knowing how quickly I get things done it'll probably be summer 2012.... Too bad I don't get to participate in the cam comp; this is exactly the sort of thing that gets me motivated. Frown

Ok, now you look guilty.
Cool

Aric,

Would you be willing to post up the data that fits your chart for your current prototype of your cam? Understanding, of course, that things change, and if it ever comes to market, it might not be exactly that.

But just out of curiosity.

Thanks!

I'm afraid I'm going to have to punt on this for now, as the cam angle/range hasn't been nailed down and will be subject to the whim of whoever decides to license the technology. Basically I found a neat way to do the springs that will allow for much narrower head widths. Kinda along the lines of how CCH took things from a helical torsion spring to a flat wound torsion spring, but not really. But that sort of 'step out of the box' change in how things are done.


EDIT- I guess I can actually answer part of the question... I'm currently thinking ~38mm wide heads just because I think that's a groovy middle of the road number (comparable to Mastercams, but there's no technical reason I can't hit at-or-below-C3 numbers for a 4 lobe cam without having to resort to wafer-thin lobes.

EDITx2 to fix mixing of units...

Very cool!

GO

Sorry I didn't get to this sooner. I haven't been online in a couple of days. Well anyway, the head on my cam is quite wide due to a few manufacturing constraints I had. That being said, using the same design I could easily get the head width down to alien size or smaller.

Sweet. It looks like a good design. Congratulations on winning.

Sorry about that Aric, I promise you that I had no idea that it would be smelly on failure.

As for what exactly "bonzing" is, It is just a word made up by myself to describe a vacuum assisted bonding process used to draw Henkel 9394 epoxy resin in throughout the cable like when you braze a cable.

Thanks again for all of your work Aric and I am deeply sorry for the stinkiness.Wink

Awesome looking cam! Smile

Except for one thing:

Moderate cam angle of 16!! Greater holding power!?

I don't know of any cam with with a cam angle giving a lower holding power than 16. Unless you are talking about misdrilled aliens. Wink

Aliens used 16 so with soft lobes in most rock I'm sure 16 would be fine.

Sarchasm: Noun. The gulf between the humor inherent in a sarcastic phrase, and the person who completely fails to get it.

Edited to add - sarchasm is a made up word (my favorite made up word). Just in case you missed that, too.

I am sorry if you didn't understand the sarcasm there. If you look through the list of specifications on my cam you may notice that it is nearly identical to this list found on CCH's website. I just copied the list from their website and changed anything that was relevent to my cam. I designed my cam with the 16 deg cam angle not for greater holding power, but simply because that is what cch uses and I wanted my cam to be as close to their cams as possible.

Thanks for the compliment on the cam, and sorry for any confusion about the features I listed.
