I tried it on about 20 trees, of all shapes I could find here in Vancouver, BC, coding on my laptop for 8 hours a day. No noticeable damage with a naked eye, using the prototype. The bark doesn't get damaged, because once everything is tightened, there's no movement or wiggling, only a compression. Most bark can handle the compression. So even if you bump into the tree, nothing's going to happen. The manufactured product will probably have some padding on the lugs, it may not be wood lugs, but maybe rubber lugs. Or metal or wood lugs, with rubber padding glued on. The way I set in in the prototype, is when the bolt of the lug rotates, the lug also rotates. So I have to set it right, and then just use it at that position. For the manufactured product, I'd like to set it, then tighten the belt a little, then allow to screw the lug bolt so that the mounting bar would become vertical. This means that the lug must have a bearing, that would make the rotating bolt (or shaft) rotate freely, without moving anything on the bark, so that the bark doesn't get damaged.
