If anyone's interested...

I used this to great effect on wednesday while re-pollarding an ash. It had busy re-growth and some parts were quote substantial. My rigging point was on the right hand side of the diagram. The stem two in from the left was a little skinny and would have brought the sections down too close to the summer house. I attached a pulley just behind the balance point, the sections would slowly rotate tip down, and ran the linethrough said pulley and tied off on the skinnier lead, but lower down. Taking care to get my (dotted) line right meant that the pieces were brought high, would rotate on release of the hinge and the pulley would slide between in the loop. A double whip style loop.

On larger pieces the groundies could easily pull in the slack beacause of the increased MA.

Hope that makes sense.

are there trees either side of the tree that is coming down? if so you could have two climbing systems, one in each tree

link doesnt appear to be opening for me

no just the one tree.

 

really....all the obvious options have been exhausted

...and relating to this thread, i thought that you could tie off lower down on your TIP tree, to swing the pieces round.

nah not enough ground clearance. the bits will swing straight in to the beech standards that were planted a few years ago.

Daisy chain a strop with a figure of 8 attatched to the condemed tree put the running end of a second rope through it and then have the groundy act as slack tender, as you climb slide the strop up but DONT leave any pegs or snags If the tree go's then the groundy lets go.

This method takes the swing away. Plus it adds compressive strength as the piece is transfered along the loop toward your TIP tree.

I should be packing up my house next week but I'll gladly take a trip up to photograph the job!
