I have a nice air compressor but the idea of pressurizing a PVC pipe device I 'made myself' is kind of scary to me.
I figured that would be the best solution but kind of a last resort if I couldn't figure out another way to do it.
The trees in my back yard are pretty tall. Maybe 50 feet or perhaps even more.
I really need to thin them out. Thats really what I should do. Before the winter and the snow does it for me.
I probably need to get a professional tree person in to remove the less healthy looking trees. which would also be a good opportunity to have them attach something at the appropriate height of one of the healthy ones, maybe a rope and pulley and weight. Using their bucket truck or whatever they call it.
