Does anybody know how to go about making sure your jig is properly calibrated?

you could use a dial indicator to make sure its moving the right amount.

I guess what I really need to know is if it is properly centered. I think my lateral may be off by as much as 1/8".

I'm not really sure if this is what a pro shop would use if they felt they had the same issue you're having, but something like this (http://"http://www.ares-server.com/Ares/Ares.asp?MerchantID=RET01229&Action=Catalog&Type=Product&ID=82281") should do the trick...

Mine is beautiful for that.
An Amf jig...it has a metal cylinder that one puts in a hole in the center.
When set at 0, 0 the drill bit should center on the mark of the metal cylinder.
Easy, beautiful....and maybe for sale again....alog with drill press....sweet!

Set your jig on 0-0.Drill a test hole in an old junk ball.Measure your pitchs with a reliable pitch gauge(I prefer a Jonel).Adjust your scale to correct.Test again,you should read 0-0.

I agree with the above. Set the jig to 0-0 and drill a hole. Check with a pitch gauge and readjust until you read the same.

That's what prompted this. I was trying to make a mold of my thumb and was having some issues with getting the thumb part centered in my slug mold. I decided to drill a hole at 0-0 (I think) and then use that for my mold. When I measured the hole it came out at 1/8 right and 0.
Problem is it's been a while since I drilled that hole and I don't remember if I really set it at 0-0.
When I put a long threaded rod in the chuck and set it at 0-0 it doesn't point to the center of the ball holder - I don't know if it's supposed to or not.
Obviously I'd like to have set so that 0-0 is really 0-0 - I don't know how to go about adjusting the jig on the press (bought everything already put together), but I guess it'll be okay as long as know that it's off a certain amount before I set the pitches.

Yes should point at dead center of cup.
Obviously you must move your jig on the attached drill table 1/8 of an inch right. As it is currently 1/8 of an inch left.

Right you are! Drilled a couple of test holes tonight and it is off by 1/8! Maybe now I can work on getting the correct pitches drilled!
