I suggest you take a piece of plywood and draw out the shape of your bypod and the size, then cut it out and trace it onto another piece of plywood and glue them together. I would suggest using 2 quarter inch peices or just 1/2 inch peice and not glue them together. Either way is up to you. I hope this will help you.

I made a set of shoots sticks by taking two aluminum rods taken from an old TV antenae, enclosed the entire rods in camo tape (makes them quite and not shine) and used parachute chord to tie them together. The chord "gives" just enough to open the legs to rest a rifle. I use this setup while in my deer stand. I've switched over to tripods (bogpod) when I'm still hunting or out west chasing elk and mule deer.
