Flight Tuning

[BT]

I want to share with you , a method of tuning a bow that is so superior to paper tuning that persons who understand the principle will use no other method.

This is not intended to be a slam against anyone who does paper tune but rather a different way of tuning for better arrow flight.
-----------------------------------------------------------------------

Before even bothering to go through this procedure lets determine if it is even needed.
Do your broad heads group with your field points out to 40yrds?
If so then you are fine and don't bother
If not , please try this method if you are at wits end , trying to make things work.

What is needed most of all is near perfect form on the shooters part and if you just are not good enough (nobody is perfect) your bow can be tuned for you by a friend who possesses such form

We must start with a bow that is timed (if dual cam) properly and a nock point which is correct.
(thats another thread ;D )

Start by putting a cardboard target on your backstop which has a cross drawn on it with visible (from 40yrds) marker pen.

Starting at 5 yrds. hold the top pin on the vertical line and fire three arrows before removing any.
Don't be concerned with the center point , just concentrate on the vertical line.

If all your arrows are grouped well and on the line you can continue.
If you need to set the sight do so now and if you cannot group at ten yards , fix it first.

now move back to 15yrds. and repeat the vertical line shots.

where are your arrows?
If they are on the line good.
if they are not then follow the suggestions below.

if the arrows are to the left of the line,move the rest to the right.
Perhaps 1/32 " to the right for every 1" that the arrow is off.
Opposite for arrows hitting right.

Now that you have moved the rest , re-shoot at 15yrds. and continue to move the rest until the arrows are back on the line.

Now go back to 5yrds. and re-shoot moving the sight pins if needed.
(normally not needed)

Now move to 30 and repeat the same as the 20yrd. test.
Adjust as needed.

Now out to 40 and viola!..you are dead nuts! right?....NO


;D :

Now we are going to make sure that there are not other little gremlins hiding beneath that perfect tracking flight

Time to shoot the broad heads

Take a good rest and head back out with a couple field points and a couple broad heads.
(the bigger the better )

At 30 yards first shoot a field point to insure that you are rested enough to make that perfect shot.
If so , now shoot the broad head.

Now you are going to shoot for that X and be sure to hold primarily on the horizontal line.

What happened?

If the head hit high then start moving the nock height up starting with1/16 for every 3" that the head hits above the horizontal line.
Opposite for low impact.

once you have it where it is on the horizontal plane , do a quick recheck at 40yrds to make sure the vertical has not changed.
(normally wont)

When you have finished all this , you will have a bow that is either the best tuned bow money can buy or... if you cant keep tune in this way , you will have a bow which cannot be tuned

Any questions?

That is how my friend taught me to tune, except we shoot at 10 & 40 only.

That would work just fine but I generally like to encourage people to shoot all the way out in case there is an issue with form.

If there is , the tuning wont work and it is going to be alot easier to pick up on.
