Bow Tuning - help!

[halfpipe88]

I've got my bow sighted in at 20 yards, but by the time I move out to 60 yards I'm 8" right.  I adjust my sight to be in line at 60 yards and I'm a couple inches left at 20 yards.  Why would it do this?  I've never had this problem before.

I would think hand tourqe or arrows , had similar problem with daughters pse adjusted the rest it helped but it ended up being tourqe for her.

Sounds like your rest might be a little out of whack. Maybe

Your left right is off......horizontal center shot

[halfpipe88]

Hand torque?  With my front hand?  I'm usually pretty cautious about not gripping the bow.  My arrows are brand new.  I just replaced them to see if it would help but it didn't.
How do you test center-shot?  I was told to shoot a group at 20 yards, then back up to 40 yards and shoot at the same point with the same pin and if it's in line the arrows will be lined up.  Sound right?

Sounds like your rest is adjusted a little to far to the right originally and arrows are fish-tailing as they come off bow.  Need to adjust rest.

Other concerns might be that you are gripping bow too tight, or that you are canting bow to one side.  Bow needs to be straight up and down (i.e., perpendicular w/the ground).  If you let it lean a little to the side, you will have the issue you are describing.

Thats one way to test center shot.  But, if you did this and they were in line at 40yrds, they would also be in line at 60 yards.  So, I'm still guessing that the rest needs adjustment or you are canting the bow to one side.

it does sound like your rest in not set up right. Try doing a walk back. shoot one arrow at twenty yards, then back up to thirty yards. Then put your twenty yard pin right on the knock of your first arrow and shoot. ( I will put a orange ear plug in the knock of the first arrow so I can have a better target to shoot at) If you are left or right of your first arrow you need to move your rest.

[buckfvr]

Could go a little one way or the other, but in alot of cases, you start with the arrow in the rest and measure 13/16ths off the riser wall to the center of the shaft.  This is only a starting point and actual  tuned measurement can vary.

 I use a laser tool mounted in the sight holes and nock up an arrow, and turn the laser from the center of the string at the nock, to the center of the shaft just past the rest.  This also is just a starting point, true tune could go slightly either way.

Aim on target, steady pin, take 1/2 step to the left, let her rip!

Seriously, time for a walkback or french tune.

My wife had a similar issue . It turned out to be her sights were not level with the string . I clamped the bow and leveled the string in both direction (left to right and up and down ) then adjusted the sight bubble to level . That solved her left to right issues .

[sirfunkeybut]

  sounds like a walk back test is in order 

[buckfvr]

start out with it set up right or darn close to it, and the walk back will get better results......start the walk back with things ascew, then you have to set it up right.  Dont put the cart ahead of the horse.............

[RadSav]

Do you have a bubble on that sight?  If so I'd expect the second or third axis is a bit off.

I had a range where all the nearby trees were slightly leaning.  I always seemed to shoot left at longer distances.  Moved my target to where I stand and started shooting from where the target used to be.  Then all my arrows started hitting to the right 

One of the reasons I stopped shooting Hoyt years ago.  For some reason I have one heck of a time shooting the Hoyt grip without using the bubble.  The side plates helped, but not enough.  Felt like I always had to be leaning to my right to get things good and level.  Just my hand and their grip do not like one another and I tend to cant the bow.  Finally had Loesch make me a grip and all the troubles disappeared.

[buckfvr]

I didnt want to have to suggest that or explain it.........

[halfpipe88]

Thanks guys.  I'll play with my rest and see if that changes it.  I have caught myself a few times tilting my bow, but it does still do it when I consciously hold it straight.  Thanks for all the tips!

[sirfunkeybut]

Any chance it could be the yoke? I can't remember the symptoms but its a part of tuning a bow

[JLS]

You can impart hand torque on a bow with a relaxed grip.  Many folks don't understand this, so they overlook hand torque as a possible issue. 

Bareshaft tuning is another good way to tell what your arrow is doing as it comes off of the bow.

[jechicdr]

The French tuning takes into account the right/left difference between close and far shot.  The impact point of the arrow at close distance is determined more by the position of the rest relative to center shot (the arrow after it leaves the bow will then try to correct its flight).  The impact point at far distances is determined by where the bow wants to shoot the arrow (a function of the bow and the arrow stiffness, weight, etc).  To French tune, you shoot at a vertical line on a target 9 feet away.  If arrow hits left, move pin(s) to left until impact point is on line.  Then shoot at 10 or more yards at vertical line.  If grouping is to left of line, then move rest to right and vice versa.  You are essentially moving the impact point of the closer shot by moving the rest in the direction that the far shot is hitting.  Then repeat process over and over until distant shots and close shots are hitting the line.

This "modified" french tuning works well.  You can fix a lot of tuning problems with sticking to this one program. 

A laser level works very well for creating the vertical line you are shooting at; getting close to the line doesn't count: you've got to hit it exactly, otherwise you'll end up with a headache in tuning later down the road. 

Move the sight frame only at 10' until you hit the line and the rest horizontally only at 10 yards until you hit the line.  Go back to 10' and move the sight frame only and back to 10 yards and move the rest only.  A few times back and forth, and the rest and sight frame are set.  All that's left to do is broadhead tuning at 40 yards to get the nock height/rest elevation set to where broadheads and field points hit the same, and then set the pin gaps for the yardages.

With this system you can tune your bow in an hour with about 50 shots, and the end result is excellent broadhead flight and, more importantly, confidence in your shooting and the ability to re-tune anytime you want/need.

A trip to Ranch & Home for some help turned into leaving my bow overnight to get a new cable & string, re-timing the cams, and re-centering the rest and it appears to be back on track!

[bowtech experience]

just look up french tune on youtube and do that, itl solve your problem if its not hand torque or another issue

Thanks for that description!!! Just went out and ran through this process. Now I'm shooting the best I've ever shot. Thanks!

Lots of helpful information-  WTG folks!!
