A few rigging questions

[jim454]

I try to set rigging points that allow my rope man to put the piece on the ground without ever really stopping it.

Yep Blinky,

I call that a controlled fall and use it as often as possible.

you can set rigging up so none of the rope touches any part of the tree except the couple of meters you use to tie the pieces your cutting.
clear paths for rope going through pulleys linked to grcs or friction drum is the way to do it and it is possible on most trees.
any extra friction created by poor rigging will limit you at some stage

my bag always has eye slings of different lengths a porty a arial block. if it's pitchy use the block beat the slings not the ropes and if your sling isnt long enogh there is always that short rope i always keep that is sacrificial use it for any thing even to save a sling and you don't have to feel bad. always keep the short scrap ropes they will be used. Oh andsteel biners are always good

3 wraps sound a bit much you'll likely lock off a climber yet if you keep that up

I'm glad I don't have to work with conifers that much... But, I do wash my ropes after I do. I use "eco-friendly" detergent.

one thing that works well with natural or bocks on a porty is just simple ole communication. Start light w/ few wraps and go from there. Take a no wrap just thread it though and the climber takes a small piece. Then just add 1/2 wraps as the climber takes bigger chunks.

Right on, especially with less experienced groundies. By the time you get to the stem wood you'll both be in the groove and you're groundie will be better at picking the number of wraps than you.

I try to have my groundmen run the rope from near another tree. This way if they have to little wrapping, they can get a quick 1/4, 1/3, 1/2 wrap around the other trunk. I've only had two times that people have under wrapped, usually its overwrapping.

I'd rather splatter a shrub, or even a house, than myself get hit by a locked off log.

Good communication back from the ground is sometimes not present enough. As a climber, I think that its important to know how easy or hard it is to catch or hold a piece, allowing me to calibrate my cutting better.

Call and respond can extend from such things as "Come under?", "You can come under."
to
"This piece is larger than the first/ last piece, and is rigged above/ below/ to the side of the block (sometimes hard to see way up high accurately). Let is run. Stop it above the roofline with a soft catch/ let it run till the tips hit the ground, but don't let the butt flop."

Response: "Larger piece than last piece. Letting it run with a soft catch/ snub off because of target below. Piece is coming from below block, with low dynamic loading!"

Twice, I was almost smacked by locked off loads because the groundie didn't let it run. The first time, I don't know what he was doing, the second time he had his head up his... and locked it off because he thought that I wanted it locked off, for ZERO good reason.

I should say ex-groundie (not just for that reason).
