There's a number of factors that could play into whether or not it continues to grind, like how much it's work-hardening or how smooth the other surface is.

But like I said, you're probably already grinding it a little and don't even realize it. That's why you have the offseason--to test things out and to learn what will and won't work and to figure out what you'll need spares of.
fair point. Considering they both have a machined finish, it's simply the surface finish that's doing the grinding itself. But we'll see how many work hours we can get out of them before wear becomes unacceptable. One year when we tried to do worm alignment by eye/hand we were eating through worm gears almost on a daily basis. It was literally eating away at the gears rather badly but with a few spares we were able to make it through competition, so aslong as they last long enough we should be fine. we always did plan on having some spares anyway. But as you said, that's what off season is for so we should be ready and tweaked out by the time this season starts
