Title: Novice needs a little help...
Post by: leftyinsnellville on September 24, 2008, 11:21:47 AM

I'm about to drill my first thumbhole.  As my span is 5 inches I want to drill with a reverse pitch of 3/8".  I'm not really sure how much to adjust the doohicky that holds the ball.  Please take a look at this photo and lend me your expertise.  Thanks!

 How do you have the ball sitting in the jig ? Thumb up or thumb down ?

I always mark which way the hole is pitched with an arrow. Example - rev in thumb, arrow would be pointing away from the grip center. Remember, what you are doing is  simply moving the center of the ball so the centerline of the drill will pass on one side or the other depending on whether your putting in forward or reverse. As far as moving the jig goes, it should be easy to see which way your moving the center of the ball. If your still confused I suggest you find a junk ball to practice on and always double check that you've actually got the pitch set correctly before drilling. Good luck.
