Building a deer stand. The stand will be a shooting house, 6' X 4'. The platform is 8 feet above ground. It will be on 4 legs, each being a 4X4. (like the one in the pic below). I have to precut the braces as I cant haul it out completed (have to put it together when I get to the spot).

If I put each leg at a 10 degree angle (angled away from the 6' sides), how long do I need to cut the 2x4 braces to band the legs on the short(4') sides, 2 feet above the ground. I know the ones on front and back (the 6' sides) will be 5'9".

Now, I know someone will be tempted to say, "just go measure the ones on the stand in the pic."

Problem with that is, it is an 8 1/2 hour drive away from here, and I built it in 2009, and dont remember the lengths of the braces.

Thanks for your help.
