About a year ago I hung up my saddle to take a job consulting and doing citywide inventory work, etc.

I didn't stay in touch with this crowd like I should have but I'm rectifying that.

The THT from Xman was just coming out I know Sherrill sells his stuff now but does anyone have any reviews or info on how they like the THT, how it helps out there jobs etc?

Hey Kevin no input on the THT but welcome back your presence was missed.
I literally just thought the other day that I hadn't seen you posting around here in a while.

Thanks man. I haven't felt like there was much to do on here for me consulting and inventory you have to fit into a premise cookie cutter unlike climbing where your thinking process doesn't stop. IMO. So I needed some rejuvenation so I'm back here and I dusted of my rope the other day just in my back yard but mmm it's a calling for sure
 
Thread going on THT. Under its new name Safebloc? It took longer getting it to market because they switched manufacturer I believe and David was not happy with first runs of hardcoat on same.
 
August has posted vids on youtube using it some. Lawrence (Phanner Man) has posted vids of working with it a lot. David has posted vids of it in use and allowed August and Lawrence, I believe, to put up video footage of his while working a job together.

Lawrence has worked with me and used it in ways that are just amazing to control bigger weights than I would expect. I believe he is working toward putting out a rigging series of info similar to "The Shultz Effect" SRT info, that will probably feature Safebloc and double Safebloc usage a lot.
 
As a climber I don't work with big weights when rigging stuff out. But, for those with proper ground support and after working yourself up to it, I belive that a single Safebloc allows the climber to rig down 500 lb and double Safebloc takes that up to ???

Friction multiplied ends up being enough to break the rope, right? It is multiplication, not addition, when you have a friction device controlling the lead into your friction device, isn't it?
Because I hold about 50lbs (a guess) when I have appropriate friction for lowering quickly, and if I was holding my 50 leading into something that multiplies the load I can handle by 10, then going into something that multiplies similarly it becomes absurd quickly.
Or am I just completely wrong?
 
The way I think about friction is more like subtraction. If the piece is pulling on the rope with 500 lbs of force and my hands are pulling with an opposing force of 50 lbs and the rope is not moving, there must be other friction somewhere taking force out of the rope (opposing the pull) and loading the rigging points (porty, block, safebloc, trees).
The friction you have throuout the rigging removes energy from the rope. The multiplying forces are primarily caused by angular changes in the rope path at anchor/load points.
 
That last explanation is closer I think. And in addition to that the 500lbs of friction (in this example) is applied near the load. If it was all applied at the ground and up through a frictionless block you would be applying 500 for the load plus 500 to hold the load - total 1000.
 
Friction and load can be mysterious the way they act on one another, but they are different. The basic idea of the rigging point adding friction is that it takes some force out of the rope, deceasing the multiplying effect of loading one side of a rope angle. So simple, I know!
Experimentation is the best way to figure it out
 
WATCH trees when people rig stuff out of them. I had the fortune to have watched good rigging and bad rigging load up a tree, and it's actions will tell much more than words.
