Here's a lok on I build, hunted out of them for years. Actually this is a picture of a buddies, mine don't have seats, I prefer to stands. One sheet of 3/4 inch treated plywood, some 1"manilla rope, and some outdoor carpet or no skid tape/paint, and some screws is all you need. One sheet will build 6 stands.....I use every inch of a sheet. To hang the stand, hold itparallel with the tree put the rope around which passes through some slot and holes in the stand, and then it goes throughv-notches on thebottom of the stand.....pull down from the front and the rope and stand tightens to the tree. It's difficult to explain, but if your interested I couldshow you somestep-by-stepdirections. No worries on scarring the trees, I use strap on steps and the stand doesn't hurt the tree a bit. If your interested, I can post or email the specifics. It's a really slick idea, at least I think. I'll post my other stand in a few. Oh yeah, and liquid nails on all the joints will prevent any squeeks. The design also lets it to be backpacked in with the rope... Like I said, I've hunted out of them for years and got most of my buddies hooked on em'. There about $15 bucks apiece once you figure in the rope. A poor man has poor ways.....and for all the skeptics, I wear a safety belt, but haven't used it yet.
