Charlie:
I am of the opinion that you can pretty much kiss that gear good bye! If you try to re-center the worm on the wheel you will get even faster and uneven wear. Look carefully at the gear and you will see why.
I have exactly the opposite problem. I have a Gemini GI-1 and some meat head who had it before me tried to lap the gears. He totally trashed both worms. Luckily, the worm wheels are OK. The worms are trashed, though.
Here is a picture of the results of someone who has no idea what they were doing! I have just finished turning a new worm for the RA axle and will make another one for the DEC axle. A picture of the new one will follow.
