Sorry for the off topic query but a few years ago I saw on this
reflector a
link to a site which showed a design for a system of two poles and cords
which was used to drop a weight over a tree bow and get further up the
tree
by stages.
I cannot use a projectile since there is a house immediately behind.
Anybody spotted this design?
Thanks

Don't know that technique Martin, but I have seen one or more party-type
Mylar helium balloon - the kind sold in grocery stores, etc. - used
successfully. It requires two people, sufficient room and quiet air. Two
light threads are attached to the balloon(s). One thread is held by each
person. The balloon is allowed to float up until it is well clear of the
top of the tree, then one person walks around the tree to the opposite
side, keeping the thread clear of branches, until in the desired
position. Then one person pulls the thread in while the other lets
thread out until the balloon is back at the ground level and the thread
is draped over the tree.
Now a string, then a cord, and finally a rope is attached and pulled
over the tree.
It's important that no power lines be where a runaway balloon and thread
can reach them.
