I've heard wages for toolroom work from the low $20's to $50. But it depends on seniority, union/non-union, field, location and local economy, etc. You would probably get a good rundown on the practical machinist forums:

Hmm, looking and it seems like no one lists pay...check the General forum and ask about wages...
