[QUOTE=fastetti;4113993][/SIZE]Personally, I'd get those steal supports for the platform that they sell on Sportsmans guide for $80 then build a box around that.

I am not sure I would have to have those if I angle the uprights.
What size would you recommend? 4x6 4x8 6x6 or 6x8
I plan to use it for bow and gun hunting. I will probably only make the platform first so I can use a pop up if needed. I will put the sides on later because mostly of 'time' and money. I was thinking of strapping it to a tree shaped like your first three fingers. Strapped to center branch and uprights in the front with 45 deg braces from the back to front uprights. After straps are tight bolts will be screwed through frame to tree to tighten tighter. Do you think this will work or should I have four uprights? Originally it was for just the extreme cold to be able to sit all day with a heater.
