Title: A&H limbs upside down for three under
Post by: Brad Isham on May 30, 2012, 08:00:00 PM
I just found the best thing for my three under shooting. I love My A&H screamin' fast longbow but it was always loud shooting three under. I reverse tillered it by 1/8th inch by putting the top limb on bottom and bottom on top. Smooth, quiet, and fast. 60# 66" shooting a 650gr arrow 187fps.
What's not to like???

Most bowyers tiller even for three under.

When you paper tune that does the paper have to be upside down?

So would that be 3 under or 3 over?

Stringwalkers in competition have been inverting limbs for years, one of those "secrets" about the dark art.  I am not a stringwalker anymore, but even or reverse tiller always worked for me in the past when shooting below the arrow.

It's actually a 1/8th inch negative tiller now. The next step is that I took the medium grip handle and cut 3/8 inch off of it. Scary cutting a four hundred dollar riser on your bandsaw but I did it. With the lower wrist it's even quieter. I think it's all about the limbs returning to brace as close to the same time as possible.

While I know that not all chronographs are created dead-on equal, unless you have an exceptionally long draw length you have a bow that is shooting 11 to 1 arrows faster than the bows Blackie Schultz has chronographed with 9 to 1 arrows @28" in the monthly technical reviews for Traditional Bowhunter Magazine.

I agree Jim.  Either my Chrony or ACS must be a little slow.  I have a 60@28 A&H 62". I pull 28.75"  12 strand D-97. shoot 3under with a clicker.  629g goes within 2 fps of 186 fps every shot.

I'm curious how high did you need to go with your nock pt to tune it.  Both my ACS need to be about 7/8" high to bareshaft well.
I might switch my limbs and try it.
