paper tuning

[GregMcFadden]

How much effort do you folks put into paper tuning,e.g. when is enough, enough?  This is the first time I have gone through the trouble of doing most of the setup (that which does not require a press) myself, and I have the bow shooting so that on average the tail end of the arrow at ~5 yards is around 1/16 of an inch above (as best I can tell by drawing circle around the tears) above the tip.   deviation is on that order, shot to shot.    I still need to get back out to the range for some longer distance shooting to see if this tuning helps any (when I started, the tail was hitting about 1/2 inch high and 1/2 inch to the right)....

I like to have a perfect bullet hole.  Also you should be closer to the paper.  More like 6 feet.  At 5 yards the vanes have had time to start correcting flight.

The real test is whether it will shoot broadheads well.  Try this link.  Some of the info is dated, but the tuning is still accurate.  I think it may help.

I'll re set up at 5 feet or so and try again.  should be interesting

thanks!

Many bows won't shoot their best with a perfect bullet hole tear in the paper once you put a broadhead on.  I use the paper tuning as a starting point and try to get within 1/8-1/4" tears and call it good.  Then I work on broadhead tuning for my hunting bow; once the broadheads and field points come together in their grouping, then the bow is as in-tune as it can get, and all I've got to do is set the pin gaps.  For my target bow I'll do a Modified French Tuning double-checked with a walkback tuning session.

i have had perfect success with bare shaft paper tuning at about 5 feet until it is a perfect hole, then puting an extreme helical on my arrow with whatever vane im using. then i can put any broadhead on that passes the spin test and shoot within about an inch of my field points but every broadhead shot is dead on. i always cut vanes if i dont spread out my shots.

spot on...... Todd... when my bows are tuned to shoot there best...I get a 10 O-clock tear.
I never START  with paper on MY bows I set the nock point and then French tune...after that I will group tune the nock point.
I track all my shots
the 1st pic is 36 arrows at 60yards.
the 2nd is 36 arrows at 60 yards after a SLIGHT movement of the nock point
the 3rd is 40 arrows at 70 yards
you have to make notes to bad shots on wind....as you can see when I get lazy I start to collapse on the shot and I get arrows out the right.
when you get the bow tuned good its all down to form

for the novice (me) - would you explain modified french tune and walkback tuning session?

I'll see if I can put it into words.

Modified French Tuning:

This sets the rest windage only and the sight block windage only, but it almost always makes them perfect.  xXx's group tuning will set the rest elevation (or more properly, the nock point location).
 
From 9' away, shoot at a true vertical line (I use my laser level)
Move only the windage of the sight until you hit the line on the money a couple times; where you hit up and down on the line doesn't matter, only that you hit the line.
Move back to 10 yards and shoot again
Move only the rest windage until you hit the line (Left miss means move rest right and vice versa)
Once you're hitting the line at 10 yards move back up to 9' and move only the rest until you hit the line
Move back to 10 yards and move only the rest until you hit the line
Repeat until you hit the line at both distances without moving anything
You've got perfect alignment with rest, sight windage, and centershot.

[Todd_ID]

Walkback tuning allows you to set/check your centershot location at different ranges.

Shoot 2 shots from 20 yards at a point near the top of the target
Shoot 2-3 shots from 30 yards at the same point using your 20 yard pin
Shoot 3 shots from 40 yards at the same dot using your 20 yard pin
Your resulting pattern will be dead vertical (I) if your rest is in the proper location
A / pattern means the rest is set too far to the left, move 1/32" right and shoot all groups again
A \ pattern means the rest is set too far to the right; move 1/32" left and shoot all groups again

After a couple times through this you will get the I pattern, and your rest is set properly.
If the I is in line with the dot you shot at, then your sight block windage is correct
If the pattern is to the left of the dot, then move the sight frame left and re-shoot.
If the pattern is to the right of the dot, then move the sight frame to the right and re-shoot.

I was planning on walkback tuning next (when I get a chance to get to the range and have a distance further than 10 yards), but so far I rechecked the paper at ~5 feet and they are bullet holes every time...   so we will see.   

thanks all

Greg,
The Modified French Tuning is perfect for those that only have 10 yards to work with: like a backyard or apartment complex yard.  In fact, I think it "Modified" for this very reason.  The normal French Tuning is done at 4 yards and 60 yards (or wherever a long range pin hits at close and long ranges), but the process is the exact same.  French tuning is good, but you've got to be a great shooter to get any meaningful feedback at 60 or 70 yards, but any of us can get darn close to a line at 10 yards and be able to repeat it.  Maybe give the modified version a try; at least it gives you a reason to shoot in the backyard where you don't have 100 yards to play with.

[GregMcFadden]

I might just do that.  (not that I need a reason to go to the back yard and shoot, I shoot 20-40 arrows a day between getting home from work and dinner, I find it relaxing, most days)

thanks
greg

you can do it at 4 yards and 40 yards ...Mon. on my day off, I will take some Pics on how to do the walk back tune..

[dreamingbig]

Todd, thanks for the modified french tuning lesson.  That is some great information; I haven't tried that approach yet but I will on my next set up.
