cam inspection quality

Was inspecting my cams and noticed that the raised portions of the lobe have worn over time and getting close to the base.  Asking if it ever wears so that everything is even, is that a time to replace them?  or replace them soon?   Or it doesn't matter at all and buy beer instead?

Do you realize that some cams are made without any ridges at all?  (Mostly small ones these days, but Metolius used to eschew ridges on all sizes in their PowerCam line.)  So as long as there's not obvious flat spots, I wouldn't be too concerned.  YMMV.

I can't really comment on the state of the cam lobes. Well, I can - but what is the point?
But, I think you should have a few beers, and use empty cans in this manner:

Go buy some beer.

Well then it's a good thing my town is oversaturated with micro breweries

Sure there is - over saturated is just another name for super saturated. True that.

To the OP, I have some getting that worn. While I have not retired them, I do tend bring them when there is a chance of needing bail anchors. :)

I was referring to the fact that you can't have too many breweries.

Ah me and my tendency for going literal a bit too often.  Cheers!

I wonder if anyone has done any testing to see if the ridges make a difference in pull out strength in a parallel crack? Would not matter in a constriction, I'd guess.

I'd get a hacksaw and carefully saw them back in if it were a concern. Also Ive read about BD testing old gear. I think it was soft goods like old ropes and webbing. Shoot them an email. If you decide to get rid of them, maybe send them to BD and have them tested so we'll all know. You could also test it yourself. The UIAA test are crazy simple and its easy to find there methods

Seconded.


Hacksaw blades tend to wander, use a dremel instead

And if all of them have jumped onto the excessively over-hopped IPA bandwagon, then yeah, you can indeed have too many.

Are you trolling or simply out of your mind?

Fortunately I am a fan of over+hopped IPA's, so it doesn't affect me negatively.

I make a lot of my own gear including cams. Also work at a vehicle testing facility to i can test it as well

Dremels heat the metal and can change the properties depending on the alloy. A small file would work too. Youd only take maybe 2 draws. The last cams I made I think it took 3 draws to get to depth

Teeth in cams are not necessary. As Mike pointed out above there are brands without. Most brands put them there because people cannot wrap their heads around physics principles and fricition. The ridges make us feel better mentally. 

Guideline #1: Don't be a jerk.
