it is not you can change it at this point by making an arc from each finger using the
proper span for each finger. By following this process you have check points that allow
you to prevent a costly mistake.
14.
Place the bit in the chuck needed for the thumb hole
15.
Loosen the front lateral locks and align bit to your line left and right and tighten the
locks. Next loosen the side locks and align the bit to your line by rotating the jig
forward or back until the edge of the bit is on your line and tighten the locks
Section (2) Installing Slugs
There are many ways to install slugs into the ball, some are easier than others. The old
way was to mark where the slug would go then drill the hole and then take the ball out of the
jig to the bench and then glue the slug and drive in with a hammer, then cut the top off of the
slug and remark the ball and put back in the jig. The following steps are the simplest
procedure and you will find to be the most accurate.
1.
Mark the ball as you normally would for the correct span (Remember that if using finger
grips and you are drilling the thumb first you must subtract the thickness of the finger
grip from the full span
2.
Place ball in machine—when ready to drill the thumb hole set your pitches then align
the ball using the drill bit for the thumb size. At this point it is just to align the ball.
When everything is aligned and you are ready to drill remove the thumb bit and replace
it with the size for the slug you want to use. Next drill into the ball until the point of
the bit is in the ball and stop. Take the slug you are going to use and hold it up to the
rule indicator on the front of the machine. Doing this allows you to determine the
proper depth so that you leave only 1/8
th
inch of material above the ball. Drill the hole
to that depth.
3.
Remove the bit and vacuum all dust and residue from the hole
4.
Take your slug and try it in the hole to see if it is too tight. You should be able to slide
it into the hole about 1/3 of the way. If the slug is to tight Loosen the outside locks
and roll the ball forward towards you and lightly sand the hole being very careful not
bevel the top of the hole. When you have it correct loosen the outside locks and roll
the ball back then place the slug bit back in the chuck and use the bit to realign the
ball. When complete you can pull the bit back in the hole.
