Rigging block and sling combined with a bull rope. And a rope man who knows how to reduce shock loads so he doesn't break the rope or kill the climber.

The safest way is to let gravity do the work, hammer it down. Push all the blocks so they hit the ground in the same spot, get the groundsman to build walls with them. It is o.k. to hang blocks or logs from another tree-not the one you are in. People have been killed when they used the tree they were in as a spar, be safe, a little topsoil and some seed for the customer with an explanation of why.

I agree with you clearance you way is the safest way but alot of the time you just can't. I did a zero ground impact job last month it was 28 trees 2 of which were well over 30 inches. I got one on the ground and had to go get 5 more men to help catch up. I blew out 2 6 inch limbs holding adjecent trees up so's not to impact the ground.You dont want to blow up trees it was the 3rd time in over 12 years of serious rigging.
Two months before that I did 7 28 inch sweet gums. I blew a top onto a bull rope rigged below my tie in point I didnt realize how much it weight and I didnt pull enuff slack into my climbing line to account for the rigging forces.
What happend was sence I was tied higher than my safety the force when the top loaded the bull rope the leader swayed so much that it actully pulled my steel core taught and pulled my spikes above my head:bang: .I thought I was gonna do a flip and my steel core would be crossed into a 8.
I gotta remeber when im roping into or below my tie in point to pull plenty of slack into my climbing system and expect the sway to come back when rigging heavy loads.

I have to disagree with you both. It can be safe to rig from the spar you are tied to. It requires a lot of aspects coming together though for it to be safe. It sounds like you guys are taking too big of pieces and not having a knowledgable groundman that knows how to minimize shock load. But, if there is significant decay in the spar, then yes I agree, do not subject it to loading.
Xtreme, those are some close calls, be careful man. Thanks for sharing your experiences so others can learn from your mistakes.

Biggest problem blocking wood down is caused by ropeman taking too many wraps and not letting the pieces descend after cutting. Holding the rope tight when blocking down causes enormous stress on the rope system and the remaining tree itself. While doing any type of rigging a good rope man will always have the rope and the cut piece moving and this will lessen the impact at the rigging point and keep the climber from becoming a tossed salad.
Cut and throw not always practical in a backyard, watched a guy drop a 5' block of wood onto an underground sprinkler line, nice 30' water gyser turned the whole yard into a swamp in minutes. Contractor had marked the heads but not the lines.

This is the method talked about. Make sure you have a good rope man.

No chit Justin?
Kenner i think, the block slapping down or the running, loaded rig line can cut/damage life support lines if they are not over block rig when system is loaded. i trust there is a face to get load to lean over and yet not rip.

Thats a really good point about not having the working end of the line in-line with the spar so you don't pinch it with the log. I see that being overlooked a lot.
Also, groundmen... LET THAT ROPE RUN!

Whoops, TS, I went back and re-read your post and thats not what you were talking about. Good point though.

True. Alot of people put their life support lines above. I dont like to. If the rope guy messes up, holds the log, and it jars the spar there is a chance that the life lines can slide off. I use a cable core lanyard just in case the loaded rigging line does come in contact. Usually, the sling rests against the life lines and it doesnt put alot of pressure on them. Yes, there is a cut in front, a mismatch cut.TheTreeSpyder said:

Sometimes i have a notch, this day i was kinda in a hurry and was just making a single cut in the fromt about a third of the way through then come from behind with the back cut.
