I feel an idiot for not being able to get this damned thing fixed myself, but I have a smallish bench mounted metal cutting bandsaw of good quality. OK, she's done a bit of work before I got her, but there's no wear in the bearings and the cast iron wheels run true. I have played with blade tension (tighter seems more reliable) and with the top (none powered wheel) tilt, which is adjustable, and the blade guide ball bearings, which are adjustable, but STILL the blade will suddenly jump off one of the wheels. 3 things look less than perfect. the wheels had some sort o gritty coating, when new, like coarse carborundum paper, this is now quite worn. The blade makes a noticeable jump as the welded part passes through the work piece. Nothing much, but when worked hard it is audible and can be felt. Finally the blade is quite old and not as sharp as it might be. Cutting alloy makes the blade come off more than steel.. Can anyone with experience of these machines point me in any directions to look to? Thanks!
