thanks again. I checked the yellow pages online and there's a shop about 25 minutes away that claims to be able to do the work. I mentioned that I've had it a year and hadn't used it and he seemed to know that it would need some work like oiling and lubing on a regular basis, especially from sitting, so he seemed to know what I was talking about. The guy I talked to isn't the one that does the work on machines but at least he seems to know something about them.
