For the several bows I've made, I put the tillering stick on the centerline of the bow and tiller the top and bottom limbs to curve equally. I cut the shelf an inch above the centerline. Is this any reason to tiller the limbs differently?
I've read that bows designed for three-under are tillered differently than split (can't believe 99% of archers would notice this)? I've also seen it stated that if you shoot a fixed crawl the bow should be tillered with the lower limb slightly stronger.
Is different tiller of the limbs something I will actually notice as an average archer?

When I set up my bows I make the center of the handle the center of the bow and make the arrow pass 1.25" above center. I also tiller so both limbs to bend evenly until the last few inches of draw then make sure the bottom limb slightly stronger.
I don't use a 3 under or a fixed crawl so I don't know how to tiller for either.

3 under even.split 1/8 stronger bottom. Get them built either or. But whatever it is moving nocking will cure it. And yeah most can't tell the difference.

Measuring the tiller, or a tiller measurement from the string to the fades top and bottom can be plus or minus an 1/8" without a noticeable difference if the limbs are balanced out correctly and bending the same....
Balancing out the limbs is what "Tillering" really is. its seldom adjusted with glass limbs and is typically done with tapers and wedges in the lay up. But it can be fine tuned. its a different procedure with glass and carbon backed bows than self bows fine tuning the balance. ones that are out of balance produce a buzz, and have more noticable hand shock.
You have the right idea ptberger....
