Jawge, Your looking through the wrong lenses in them trifocals again
The bow and form in the last picture is setting on my tillering tree. Works slick, set a level where I clamp the handle, then set the level on the board with lines, Clamp the bow in place, attach the tillering string, and usually sand back 4-10 feet to work the limbs depending on where I'm at in the process. I find myself standing further away when early tillering and closer to the bow when final tilling.
