When the tillering goal is no set

[willie]

I used the yard stick method on this build early on to get me to good clean brace. Once there i knew i was headed in a good way with this bow.  I also paid very close attention ..............  The yardstick method bassically takes overall bend of each limb independently for consistent bend and then comparing them with each other. using the straight edge of the yardstick laid accross the belly of the bow while bent to get a good view of the bend early on has helped me creep up on it. 

Hi Dave,

is this the yardstick method you mention above?  seem to recall a post where you mentioned more about your method, but cant find it now.

I don't get in a hurry tillering a bow, it is a week project of shooting and checking for the slightest anomaly with my gizmo, I am only using 220 grit sandpaper at the end of the tillering process.

I got a few 1/2 finished builds in the corner from being in a hurry and  gotta say that 220grit for tillering suprises me.  80 grit here.
when I take a break from tillering because my eye tell me two different things, breaking for another cup of coffee doesn't help.
