RE: Homemade Tree Stands
Not real sure what you mean by a box with a cut out. But if you are looking for a ladder type or tripod from 12 to 16 feet look in Cabela's or Bass Pro. In the fall Rural King farm supply has tree stands of that nature here in the fall. If you are talking about what I call a box blind that has four sides, window, roof I have seen some starters that use 4x4's for sale, same places as befor. Wasn't there something like this on the home page here once? As for ready made plansI do not believe I have ever seen any but there must be some out there.
Good luck on your quest.
