Tubing size for stand? Window size?

[tef]

Building a rifle blind, need advice on what size sq tubing to use. Is 1 1/2" over kill? (Box frame) . Using 2" for legs.
Also, using deerview windows- is 24x10 a good size?
Thanks

I use 2" 14 gauge. I think the wall size is important to eliminate flex. Too thick costs too much but too thin and the floor flexes. Flexing causes sounds in the wood structure. Angle iron works real good and there no place for water to get trapped and start rust or freeze swell.

Good point, thanks.

This is what I was going to suggest.
I picked up some brand new 2x2 angle at the scrap yard couple years back. Not full joints, but pieces. And the pieces were just the right length for a box blind. Before I made my frame, I drilled some holes in it. Once I framed it up, slapped the plywood up, drilled thru the plywood and bolted.
Think I paid 25 cents a pound for the angle iron. Bought all I could pull out.
