Things To Consider:
• The larger the blade surface area, the more steering ability
the broadhead will have. Therefore, larger cutting diameters
are harder to tune and may require more fletching
and slower speeds.
• Mechanical broadheads still need to be aligned
to spin true.
Step 1: Tune the Bow
If you want broadheads to fly like field points as much
as possible, you must be able to tune your bow to shoot
perfect bullet holes through paper at 5 ft, 15 ft and 30 ft.
Broadheads will react exactly opposite of a paper tear. For
example: A high tear will result in a broadhead that impacts
lower than a field point because the broadhead blades are
steering the arrow in the direction the point is forced.
Step 2: Broadhead Alignment
There is a tolerance between all broadhead manufacturers
broadhead shanks and the inside diameter of the
insert itself. The best way to illustrate this is to wiggle the
broadhead right before you tighten it down. You will notice
a little play there and depending on where the center of
the point ends up when it is firmly tightened, will result in
either a broadhead that wobbles or spins true. To correct
the problem and make all of your broadheads spin true,
use the following steps.
1. Use a spinner like the Pine
Ridge Arrow Inspector and
a box to put the point up
against. You will be able to
see if it is spinning true or
wobbling. (see figure 1).
|
If it is wobbling you will see
a circular motion created by the tip of the broadhead as it is rolled on the
spinner. If the broadhead is properly aligned the point
will stay stationary as the broadhead spins.
2. Rotate the arrow to the high side of the circle and
mark the top of the broadhead with a marker.
(see figure 2).
3. Rotate the arrow 180 degrees opposite of the mark
and press the tip of the broadhead on the counter top.
(see figure 3).
What you are trying to do is push the
broadhead around slightly in the insert until the tip is
dead center in relationship to the center of the shaft.
The reason you mark the broadhead is to see if you have
applied too much pressure or not enough.
With a little
practice you will be able to align the broadhead to the
arrow in less than a minute.
Note: Every time the broadhead
is taken off the shaft it must be realigned. You may
need to realign the broadhead during practice also, as
impact can affect broadhead alignment.
4. If you are paper tuned and your broadheads are
aligned properly and still experiencing problems with
grouping, then you need to consider creating more drag
on the rear of the shaft with a fletching change. Consider
feather fetching, a four fletch configuration with
2.5”or 3” vanes or small vanes (2.3”) in a 6-fletch pattern. |
