I've been using a HF 7x12 band saw for about a dozen years and haven't had any problems that I couldn't easily solve. However the free wheel has started to really make lots of banging sounds. After removing the blade I found that there was noticeable wobble in the wheel. I removed that wheel to assess the bearings but found the wobble to be in the shaft. The shaft is solidly fixed in the Sliding Draw Block which is bolted to the Blade Tension Sliding Block which is captured by a pair of sliding guide plates. The slots in the guide plates hold the sliding block with no apparent slop but even with all bolts firm, the wobble persists. Your thoughts?

The 9-year old Uyghurs putting those things together have no concept of quality control?

Welcome to the Forum from Southwestern California.
Maybe the Chinese have copied the concept of planned obsolesce from Detroit's big three.
A dozen years of use has exceeded the warranty.

i found the problem. A short time ago while cutting a big, unwieldy part, at the final 1/8" the steel twisted out of the vice. The steel then was pulled in contact with the guide rollers and forced the blade off the wheels. Yup, scary to say the least. A close inspection revealed a tiny crease in the blade...hardly enough to notice, but enough to cause the upper wheel to bounce every time the errant blade rounded the wheel. Replacing the blade brought back the old ****** back to it's former self.
