I need a quick, on point answer about how to attach a block to a horizontal branch.
Here's the deal: I just bought an eye sling and a block and a port-a-wrap. I was going to attach the block to the vertical branch with a timber hitch, then run a rope through the block to the piece to be lowered (the lowering wood was attached with a running bowline). But the "Tree Climber's Companion" said you shoud only use the timber hitch to lower vertical wood. In other words, the timber hitch should only be used when the bite of rope is 90 degrees to the tree. Another way to say it is that the timber hitch should only be used to block down a trunk (vertical wood) because otherwise it might slip.
So how should I tie the block to a horizontal branch for lowering wood?
What I did - as an experiment - was attach the block by making a half hitch around the block, then just wrapped the excess a few times around the vertical branch, and tucked the excess rope under the wraps.
In summary, how do you attach a block (girthed hitched to an eye sling) to a vertical branch to use for lowering heavy wood from the same vertical branch?
