Nock left no matter what I do
 

Been trying to get my new MZE tuned. Boy, its been a job thus far.

Anyway, I'm fairly certain that the rest is set up per Mark's directions. No matter what I would do; I always get a left tear in paper bare shaft or a fletched arrow. Decided to shoot a bareshaft at 20 yards. The nock end would always be way left of the arrow's impact point. I moved the rest both left and right and still experienced this. Moving it left was supposed to correct this but it seemed to get worse. I can see the bareshaft almost get horizontal in mid flight. I have checked for clearance issues and I don't have any contact. I feel confident in my form.

OT2 says I'm good on spine. Any suggestions?

Are you using the same shaft for every shot? Try indexing the nock to see if there is a weak side in the spine department.

My second thought is that the arrows are acting underspined Try turning the bow down to about 60# (two turns) and see what happens. I know that according to the charts they should be OK, but you're looking for an answer so try it.

Yes, same shaft. I believe I did turn down the poundage. It was probably around 60 or so.

Could you explain more about indexing the nock?

A lot of carbon arrows have what I'll call a lateral line down the shaft due to the way they are made (wrapped) so they don't have a consistent spine the whole way around the shaft. There is a weak side and a stiff side.

Some guys float their arrows in water and the stiff, heavy side will sink and the lighter side will be on top. Others, like me, shoot a bare shaft and get it as close as we can by tuning the bow. But if some arrows won't tune right then just turn the nock (index) in the shaft 90 degrees and try it again. If this doesn't work then turn the nock another 90 degrees and try again, etc. All you're really accomplishing is trying to get all your arrows to leave the bow the same way. It all depends on anal you are about your equipment.

Then of course, every once in a while you just run into that one shaft that just doesn't act like the others no matter what you do. That's where cut-off saws come in handy. LOL.

I find on target gives alot of combos as too stiff, when I find them just right.

I have put my faith into Ontarget a few times only to find out I had too weak an arrow.

Same thing happened to me recently with my PSE Mohave with medium wheels set at 67#. Said my beman 400's were fine, but I had to move up to .340s.

It calls my currently liberty setup with carbon express Edge's 350's too stiff, but I had to move from 125gr tips to 100's.

Ok, I understand now. I'll float my arrows today and find which part of the arrow has the stiffer spine and see if that helps. Thanks guys!

BowTech you say? Check that puppy for cam lean... but you should still be able to find center shot. (Even if it is way off center) Hmmm... What rest are you using? I couldn't get my Old Glory to tune at all with a drop away served into the down cable. Got rid of the drop away attached to the down cable and BINGO! problem solved. I don't know what it is about the Binary Cam that is so sensitive to cable tension but it's not the first time I've heard of this.

Edit: I see now NAP 2000. My NAP 3000 had a mysterious nock right tear I couldn't get rid of on the BowTech (It works great on my Hoyt though...) I put on a Whisker Bisquit and all the tuning probelms went away.

Well, actually I haven't updated my sig yet since its not official. I've been trying to tune the Zero Effect. Just wasted another few hours again today. I have no clue what I'm doing wrong, if anything.

I used different size tips, arrows, moved my rest both left and right, tied in another string loop (nock pinch), lowered my draw weight, etc and I still get the nock high-left tear. I'm giving up.

In case some of you are wondering, I didn't rely on paper this whole time. I shot a bareshaft out to 20 yards and its always nock left of the impact point. I am certain I have the rest set up to Mark Land's directions. I even called him twice to make sure.

Jees! My brain is fried. I should've seen MZE in the first sentence of your post but I missed it for some reason. I'm stepping away from the computer now.[&:]

RE: Nock left no matter what I do
 

Can't believe I didn't NOT see this mentioned. Have you checked for cam-lean? If you have it and it's severe enough there is no way the bow will tune.

Seems like you're trying everything we and you have thought of. Guess we need more edumacation.
