I like it. However, I don't think it will work for my situation. Offhand, the problems I see are: - I don't have a place where I could build a terminal or landing zone in a tree that has easy access to the house. I would need to go up between two trees and then walk across a bridge of sorts to get to the house. It can be done, but it won't be easy. - I'm rather old to be doing such things. Climbing the stairs wasn't much of a problem (and was good exercise) until about 2020, when I started having medical problems and had to stop such exercises. Unfortunately, I haven't recovered my former strength. Just riding a bicycle is a problem for me. A counter balance pulley system will be a big help, but will need to be adjusted every time I carry something heavy up the tree. Hauling myself and the bicycle up the tree is possible. Hauling myself plus 40 lbs or dry firewood (oak) or 60 lbs of green logs might be difficult. - If I haul myself plus 60 lbs of green logs up the hill, getting back down for another load is going to require removing 60 lbs of weight from the counter balance. That's about 7.5 gallons of water, which can be done possibly with a water pump. - My problem isn't so much getting myself up and down the stairs. My problem is with the stuff I usually carry up and down (firewood, furniture, tools, power equipment, groceries, lumber, generators, etc. If I take myself and the bicycle out of the equation, a pulley or winch system need only lift the stuff without adding myself and the bicycle to the burden. I'm considering something like a small motorized steep slope "railroad" car. There are plenty of suitable designs available which I can steal: Thanks for the suggestion (which got me thinking about the problem again). It will probably be a few years before I need to build something. One very useful takeaway is the Dyneema rope: I was going to use wire rope but I like the idea of making less noise. > >You could compete against Tom in the vertical feet climbing contest. -- Jeff Liebermann jeffl@cruzio.com PO Box 272 http://www.LearnByDestroying.com Ben Lomond CA 95005-0272 Skype: JeffLiebermann AE6KS 831-336-2558
