KW,

My best friend gave me a copy of the Easton Tuning Guide 35years ago. I used to keep it under the cover of my Webster's dictionary.

I did download the Pdf version from Easton a few years ago and it hadn't changed by much.

They never did address balancing tiller by using adjustable limb bolts.

Simply put, the nock point height that is necessary in order to launch a level arrow is determined by the bow's tiller.

A higher than 90degree nocking point will require additional tiller on the lower limb in order to launch a level arrow.

A lower than 90degree nocking point will require additional tiller on the upper limb in order to launch a level arrow.

So whether the arrow runs uphill, or downhill to the rest, there will be a tiller combination that can launch a level arrow from the bow.

The original whisker biscuit was a full circle of bristles that encircled the arrow. It was a slightly larger diameter hole than the diameter of the arrow that was to be shot through it. And the tiller combination that does not create either a rising or diving arrow from the bowstring is even, which work well with a 90degree arrow on the bowstring.

The newer whisker biscuits work the same way.

The difference between banging the arrow against a rest or having that arrow leave the bow clean is often a matter of tiller.

I have several buckets of arrows that are underspine for what I would use for hunting. But if I lower the draw weight of the bow to match those arrows I can still shoot them for targets. And being able to properly tiller the bow means you can leave the nockpoint alone and tune the bow with a wrench.

Good luck hunting! >>>------------>
