Treestuff lists working load limits of 4250# for the 3/4” Ultra…and 4480# for the 3/4” whoopie. I am curious as ti how they arrived at those figures, as the Ultra seems inherently stronger by design. On another note…would that WLL be the weight of the piece being rigged, or is that the TOTAL...

Yes sir.

That was why I used it there. Not much room to run/needed to snub it. Worked like a charm. I always notch my bollard into the trunk to eliminate any chance of it shifting/slipping.

Here’s a pic of that tree. Not the piece I’m rigging here, but the next one, the one where I’m positioned in the pic, was the big one. I rigged off the one I’m rigging in the pic, then swapped to the 5/8” (new) Polydyne to rig off the big one.

I’ve got a piece, but thanks. That big chunk was rigged on 5/8” PolyDyne, using an ISC 3/4” block (not the giant one), on a brand new 3/4” TenexTec whoopie I made up. Carl took 4 wraps on the bollard and it barely ran. (Didn’t have a lot of room to run). The Ultra should be strong enough...

And would you use the Ultra for heavy rigging? My heavy is generally 1000-1500#. Biggest chunk I ever rigged we (Carl and I) estimated at 2250# I think it was. White oak…8-1/2’ long…~28” diameter, best I recall. I’m wondering if the Ultras are good for the heavy stuff as well?

I bought a Bend Right ring a few weeks back and am getting ready to splice up a sling for it. I have made/used loopies, whoopies and regular eye slings, but have never made/used an Ultra sling. For those of you that have experience with both, which do you prefer…and why? The Ultra has a certain...

If I had to work for minimum wage, I’d rather earn it doing tree work than anything else I know of. Framing is the only thing that comes close for me.

The highest I know I’ve thrown is 90’, and I only know that because I had to walk the cube to the tree to reach the bag to tie a rope on. Had to break out the APTA yesterday due to needed precision. Sweet gum growing on the bank of a creek/ditch, leaning heavily over a barn/shop. I tried five...

It’s doing okay. I’m quite sore from climbing today. Getting my strength/stamina back little by little. I’d guess I’m at 75% now. Getting my throwing arm back, but still need the APTA if the target’s over 60’ high.

Took down a huge pecan tree this morning. Possibly the biggest I’ve ever cut. Over 80’ tall, ~42-44” across the stump. Spent between 3 and 4 hours aloft, the most I’ve climbed at a stretch since getting back at it. As usual, in a hurry to get to work and forgot before pic. Snapped this one just...

Might we infer, from the pic above, that Stephen lives…in a kiln?

Ah…so not drawn to scale!

You’ll get a remarkable amount of heat off the pipe itself with that much vertical pipe surface.

Looked at them but don’t see any advantage to them.

With all the drama and propaganda flooding the world today, this song is as relevant as ever….

What model do you have? Length/width?

Look over as in pass it up, or give it thought?
