•Paper Tuning
Short range group tuning will work with any style of shooting. Best results are achieved
when this method is used after completing the Bare Shaft Planing or Paper Tuning tests.
This is a good ultra fine tuning method when space will not permit long range shooting. After
completing the following steps you will have very clean arrow flight and a well tuned, accurate
setup.
To begin the short range tuning method, you will need a piece of cardboard, or a target
face. Make a broad line through the center of the paper on the blank side, making sure the
line is thick enough to see from twenty yards. Start at about 10 to 15 yards from the target.
Use your tuning target and position the line vertically when you are tuning the arrow rest and
position the line horizontally when you are tuning the nock point.
•Vertical Impact
Position your line horizontally and shoot six arrows at the line.
Concentrate on keeping your pin on the line. Don’t worry about
left and right hits, just try to keep your shots on the line. Shoot two
good groups, discarding any rough or bad shots, and note the
vertical impact of the arrows and their relationship to the line. All
adjustments are made with the nock point during these steps.
If your arrows are not consistently grouping on the line, make
small 1/32" adjustments up or down with the nock point and shoot
two more groups. Continue making nock adjustments in small
increments. If all of your arrows begin to hit on the line you are
correcting the nock position. In the event that your groups widen,
move your nock back to its original location and make small adjust-
ments in the opposite direction.
•Horizontal Impact
After achieving a nice, straight, horizontal pattern, rotate your target
so your line will appear vertical. Just as before, shoot two good groups,
discarding any rough or bad shots, and note the horizontal impact
of the arrows and their relationship to the line. All adjustments are
made with the arrow rest during these steps.
If your arrows are not consistently grouping on the line, make
small 1/32" adjustments left or right with the arrow rest and
shoot two more groups. Continue making rest adjustments in
small increments. If all of your arrows begin to hit on the line you
are correcting the rest position. In the event that your groups
widen move your rest back to its original location and make small
adjustments in the opposite direction.
