Oak Tricam WTF!?!?!

Oak Tricam I made to protect a pocket I couldn't get a cam into.
I made this for a pocket on a climb. Anyone have any idea about how much force it would take to blow it up. There's about a cubic inch of oak between the pin and the accessory cord but I pinned it for added strength anyway. The cord is polyester 7mm from REI.

I should note I've bounce tested it in a pocket with my body weight and I weigh 205 after my morning dump.

Depends on the moisture content of the wood and which way the grain is running

Take a whipper on that fucker and let us all know at what force factor it took to splinter into a million pieces.

That is, after you get out of the hospital (If?)...

Make a rack of these things and climb Devil's Tower.

The Oak is kiln dried Red oak and the grain would be perpendicular to the direction of the force. (The same direction the sling is hanging, or the direction you would point the grain on a baseball bat relative to the force)

My experiment is not near as cool as a 350' ladder. :)

I had planned on it actually :) Just going to back it up with a toprope first :)

Hell fuking yeah! That's a GOOD idea!

LOL!

When you do it, PLEASE do post the results and photo's.

I look forward to hearing the results of the whipper. Out of curiosity, why not just buy a real tri-cam or borrow one?

This reminds me of a video I saw a while back where this guy make wood chocks from 2x4s and then tried to climb a parallel crack placing them as he went. I think your experiment will be more successful than his. Doesn't mean something won't get bruised.

^^ haha I know that kid personally. Pretty hilarious, he is a great boulderer.

If you're that strapped for cash why not go to home depot and pick up some nuts. Thread your cordlette and your good to go! I'd feel more confident about that than wood.

I've heard about it but haven't seen it. Anyone got the link to the video?

Can't be any worst than

I think people here are equating oak with the soft pine you can get dirt cheap. They most certainly are not the same.

In a good placement, that hunk of wood is as strong as the cord on it. Where you'll run into problems is with placements near the edge of the range.

Think about this, it's thicker than some pine trees I've slung or rapped off. It's a lot more optimized for the use.

I'd whip on it.

I think your angles are too steep. I am pretty sure it'd slide down a parallel crack. It's be fine used as a hex or nut though.

I think the issue with this piece is its durability. You can fall on it in a test scenario and it may hold, but there is just too much of question mark if it will hold a second fall. And if it holds a second test fall, the question still remains, will it hold another... and so on and so on.

Guideline #1: Don't be a jerk.
