Thanks to a new full static dyneema 9/16 Plasma core rigging line by Puget Sound Ropes---- (forget Samson) 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 huge Hobbs style 7/8th 5-6" sheave block, slung with a 5/8th inch spectra sling, rated at 58,000 lb, tip tied, twnsioned, 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, slung 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. I also got $900 to climb and drop two dead back leaning alders, not easy but this old man got em down in under two hours...
