i realize offsetting thumb just changes pitches. yeh yeh, but i can't seem to get that great feel by just moving pitches around lining the thumb up with the bridge. BUT, when I offset the thumb 1/4 inch left (right hander) i tend to hang up unless i make the thumb larger. should i adj my pitch a full 1/4" left?

The simple way to do an offset thumb is to have to t-lines. One For the thumb and one for the fingers.Drill pitches for thumb off thumb line and finger off t-line. most offset thumbs need to be over 1/2inch to 1 1/8 in over. Remember to take approximately 1/8 off your current thumb pitch becasue the offset will make it it come off quicker.

I use off set, no matter the argument that's there's no such thing. I found, for me, 1/8 left was the smoothest, for my thumb. I don't come out to fast, don't hang up ( unless my thumb swells a lot) but that's not the pitch problem, that's my coffee problem.

It took me 4 balls to find the "right feel" for my pitch. I used an old ball, 1 3/8 thumb slug so I could adjust pitches without plugging, just a new slug.

It takes trial and error to get the 'prefect' feel for you.

The original offset thumb was designed by Bob Strickland. Here is the basic measurenebt rules from his book. You must have 3 center lines. The center line of your grip is conventional. The center line of your thumb is through he center line of your index finger with the left edge of the the thumb hole on the conventional center line. The center line of your ring finger is through the center line of your thumb. The Index finger is drilled conventional. His theory is this will put the center of the ball in line with the center of your hand and arm. He does not state any differnce in pitches is necessary.

My thumbhole is offset. If you look at the drilling head on, my thumbhole is directly below my middle finger hole.

My span is Middle finger 4 3/8 cut-to-cut, Ring finger 4 1/2 cut-to-cut, thumb pitch is 3/8 reverse and 1/4 negative (away)

Juggernaut:
The only thing I would double check is: I'll bet a dollar to a dough-nut that your ring finger is too long. I find this a common mistake because most drillers do not actaully measure the span of the ring finger. They just add on to the span of the index finger. Put your thumb into the ball and lay your fingers on top of the ball and see if the joints of both fingers are the same length past the cut of the finger holes. If they are not, you are putting more strain on one finger than the other.

Nope, exactly the same. I am one of those guys who uses an extended ring finger. My ring finger span has always been 1/8 inch longer than my middle finger span, regardless of whether the thumb was offset or not.

My OLD drillings looked like this:

--0
0--
---
---
-O-

When I offset the thumbhole, it brought the ring finger down, almost parallel to the middle finger.

My drillers have often told me I have an odd grip, but it measures out correctly and doesn't hurt any tendons or ligaments, so I assume it is correct.

My copy disappeared from the shop and I never found another one. If anyone knows where to find one please post it.

Juggernaut... your old and new ways are exactly the same the "drawings" are just tilted differently. Maybe your pitches are different but that's it.

I've heard that before, but you aren't going to convince me of it. Not going to argue about it ( been down that road ), but I know this, one technique works much better for me than the other one.

Okay but what about these? It's probably a mental thing.

Are all 3 of these drillings different?

It looks like the MF span on each is the same but the RF span increases from the first to the second to the third pictures. -- JohnP
