I have been thinking about sending in some of my older gear to get break tested. Has anyone ever done that? I think it would be interesting to see how much holding power my ropes have left when I think they are about ready to be retired. Same with carabiners.

I like breaking stuff......gives you a bit more confidence in the gear your riding. Darin, any commercial sewing places there? they may have a test machine.

who are all those subscribers...?bots?

Northwest labs in Seattle will break test anything you send them. For a nominal fee of course.

I sent them a short hank of rope that I put in a tree in 1988. 13 years hanging and swinging in the breeze. It broke at 3300 pounds, about half of its original rating.

last fall I was putting together a 600' zipp line system for a big ugly dead white oak behind a house. Only access was down a flight of steps, up 2 flights and across a deck. We were going to zip it all out over house wood and all so I was a little concerned with stuff breaking. I set up an imitation system in my shop with the prussics that would attatch it to my loader to tension zip line , other end was spliced to go around another tree. The prussics kept slipping at about 3500 lbs which was cool to know that we couldnt break things by pulling to hard. Oh yeah the point of the post was I bought a little gismo caalled I believe a LOAD CELL, we hooked it up to a computer and put it on the end of a hydraulic cylinder and pulled stuff till it broke. Pretty fun.....

I have a local rigging shop that will do 6 breaks for $150. They will let me video each break Catch is they can't break things over 10,000 pounds.

Nick, I can do the same thing where I work, and save ya the $150. I can also expose the material to anything from a 3.0 to a 13.5 pH, and from room temp to almost 2000 degrees.

Didn't catch it on video, but broke some older HI-V I had a few weeks ago... 4340#. Not bad for sitting in my truck a few years exposed to lord knows what!

They just use their machine to proof-load stuff before they install it. Usually just swaged steel and stuff like that. They have a rope splicing crew, too..but their work is very sloppy.

NeTree- you're on!

I got to bring down the 12 KV a couple of times. Told all the boss's, "I'm not sending any of my crew up there, or myself." Face cut, back cut, Ft. Bragg to Mendocino out of power.

That was quality time.
