Tiller and Limb bolts

[JGHoss]

For the past few years I have been shooting my PSE Thiunderbolt set at 63 lbs. this year I needed new arrows and decided since I was buying new arrows I was going to bottom out my bow and get new arrows spined to my now 70 llb bow.

The Tiller has always been even, now after both limb bolts are bottomed out, the top limb tiller is about 1/8 longer than the bottom..........

Should I leave it the way it is or should I move one of the limb bolts to bring it back even? if so, what limb bolt would I loosen to bring the the top tiller even with the bottom?

I have not shot it since the bottoming out, I am waitng for my new arrows. I just wanted to resolve this issue now before the tuning process......

Thank you in advance

I'd bottom out both bolts and set the tiller with cam rotation.

What cam system is on the T-bolt? How are you measuring tiller?

[JGHoss]

The cam is the lightning cam, the cam is the lml-2 cam. I measureed both by riser limb junction to string and also by streching string from the axels and measuring to string. Both come out 1/8 top limb possitive tiller.

I dont know, I thought when I bottomed the limbs out the tiller would stay even..

Should I play around with limb bolt adjustments to get it even or should I just shoot and not worry? I guess if groups are ok, it should be ok huh?

I dont think that I would worry about it if it is shooting good.

On that single cam the tiller is measured from a string between the axles back to the riser/limb intersection not out to the string.

You may want to reread the post. He stated that he measured it both ways and came up with the same measurement.

Top measurement is larger than the bottom? Tha's weird. Usually it's the other way around as the cam is larger than the idler---most times.

Did you make equal turns on the limbs when increasing the weight? If you know what the nocking point height was then check it now for comparison. If it's relatively the same then I think I'd wait till you get your new arrows and shoot them. If things like nocking point are the same then you shouldn't see a whole lot of change in arrow impact at 20 yards or less. Maybe a hair higher. That should give you some clue as to what you need to do. You'll still have to retune the bow anyway.

Tiller adjustment doesn't have to be even. It is perhaps, a good point to start shooting the bow at and for checking specifications. But, depending on the shooter and grip it is quite possible to make tiller adjustments to personalize the bow to the shooter. I wouldn't worry about it until after I had shot it some.
