Updated Gizmo instructions with pictures.

Here’s another tip for “fine tuning” that I use to compensate for my inability to recognize perfect limb symmetry (I really envy those guys with daVinci vision). In the last few inches of tillering, I switch to a Gizmo that’s only 2” long. It will indicate minute thickness differences along the limbs, and ensure a smoother curve. Eric mentioned in a post on a previous thread, and Steve reiterated, set the pencil depth on the “weaker” limb, and use that setting for both limbs to help balance the bends and working loads.

  I do something similar, I use a 3", my regular is only 4".

Eric,

I see that the 14", 16" and 18" peg holes on the tiller tree get used a lot. Do you do much pegging and marking at full draw?

  I will very often sit down in a chair with a braced bow in my lap and start marking it with the gizmo, I scrape off the pencil marks plus a few strokes, draw the bow several times and then do it again. Every few minutes I will get up and put it back on the tree to check weight and see how it is doing.

Sounds like tillering was fun?!
