We all settle into a stave working arrangement that works for us, space dictates most of our setups. I worked in a 5'X7' offset in the corner of the garage and out under a maple tree in the front yard starting out, I made at least 50 bows under these conditions before I moved to a location where I could build a shop.
I once removed the bark and sapwood from a bunch of osage staves with them leaned up against a large tree just to see if I could. I would work what would be the top limb first and repositioning the other end up as needed. This worked surprisingly well, the downward motion of the draw knife plus my upper body weight behind the knife would peal green bark and sapwood off like butter.
I find it interesting to see how others work their wood, I doubt if any of us are exactly the same in our setup.
Here is mine, an extra heavy work bench that won't move during heavy drawknifing, a vise and a support post to keep staves from shifting in my vise.
