My advice; Don't put more than one tree on the ground at a time. You can overload yourself and have more than you can handle, wood will split, check and be ruined by bugs if you don't get to it in a reasonable length of time.
With a huge pile of osage, you split until you pass out and resume splitting when you come to. In this gag picture I definitely overloaded myself, some of this wood ruined because I couldn't get it processed in time.
Cut the tree, cut a 6' section out of the trunk, save any pieces of the trunk that are 36" and longer for billet wood to splice into staves.
Split your trunk into staves between 3" and 4" wide across the back
Don't take the bark off unless you have a draw knife and can remove the sapwood as well.
Shellac is the best sealer for the back and ends.
Buy the Dean Torges book "Hunting the Osage Bow" and follow his procedure on cutting osage to the letter. His is the best method.
