RE: Homemade Wood Treestand Plans
Yes, I see that brace but it's not much. I see that more as the bottom brace of the platform and not a tree brace to prevent the stand from falling forward. The ones I've seen and built have a brace that goes from the front of the stand back to the tree at a 45° angle. This brace and the platform forms a triangle, flat against the tree, flat platform and angle brace. I can't see the right side of your picture for the plans so I don't know what is missing. Looks like two ropes tied around the tree so there must be another, lower, portion to tie to.
