Sure, if you're Reg or Graeme.. Look for more images and video sometime soon.
Thanks to a new full static dyneema 9/16 Plasma core rigging line by Puget Sound Ropes---- forget Samson, this $800 line rules) rated at 29000 tensile, and a well place fir for a gin pole, we were able to rig two 17 foot logs, and a 21 footer, tip tied, running through a Hobbs style 7/8th 5-6" sheave block, slung with a 5/8th inch spectra sling, rated at 58,000 lb, tip tied, tensioned, held and lowered via the venerable GRCS, and butt hitched with a 5/8th Samson, rigged through a 3/4" ISC block and handled by a portawrap, sllung with a 7/8th Tenex 20 foot loopie. The largest log could well have weighed 3000 lb, and is close to 300 board feet. Will scale it out tomorrow. I have to chunk down the gin pole tree to about 48 feet, at which point I can fell the butt onto a slight side slope. The log truck will load it and the four sticks on the ground, and then I'll fell the big stick, which is about 30 feet long.... the good wood in it looks to be close to 750 board feet. The job was underbid a bit, and I hate to cut firewood when there's an alternative. Well, this rigging was risky and the GRCS barely held, but I hope to net $600-750 for the wood, which will help the job to be somewhat profitable.
We had brushed out three quarters of the limbs close to two weeks ago, had to quit due to the wind picking up, and a worker having to leave. Patrick finishing the brushing in 1.5 hours, after Wraptoring up--- had a throw line in the block we'd left...then coming down and he and Robert cleaned up the scads of duff and gazillion cones, while I got the truck and chipper out of the way, dumped, left the chipper and came back for the duff and cones. Then Pat Wraptor'd back up--that tool is so BOSS and a major energy saver--for the real work--- then we got to work on the rigging, which was a challenge... the line is stiff and slippery and the GRCS capstan's rough surface has smoothed after 12 years of use....(I want the new longer capstan) and, as will be seen in the video, we almost lost it on the first log when it came up and barely held. I'n not sure how much exactly, but these two monsters likely produced 40 yards of chips!
