HF 1 x 30 Belt Grinder

I bought one of these but the version with the disc sander on the right side of the motor.

The bearings for the two idler wheels weren't fully seated into the wheels causing wobbling  and vibrations. Fixed that but still lots of vibration. Going to make an arbor to hold the wheels into the lathe to true them up and see if that helps. Certainly can't hurt.

I had a problem with my Kalamazoo belt sander right out of the box too. The large rubber drive wheel on the motor had sharp mould line down the center of the wheel which put a crease in the center of all my sanding belts. The center of the sanding belts didn't even touch the steel backing plate because they ended up sticking out like the center of a piece of angle iron. Needless to say the center of the belts wore out quickly as it cut a notch in the horizontal platen in front of the belt.

Even after scraping off the mold line from the middle of the wheel it would still fold up the belts in the center due to the steep side angles of the rubber wheel. I finally sanded down the rubber wheel to more of a slight radius instead of the flatter angles and the belt started running flat against the backing plate. No more folded up belts.

I trued up the small wheels on the lathe and that helped with tracking but not with the vibration. I took a look at the drive wheel and it was wobbling side to side and around the circumference.  

Modified the arbor I had made for the small wheels and used that to true up the drive wheel. What a difference! Hardly any vibration at all.

I tested it by grinding a HSS lathe bit for my fly cutter. It makes a banging sound when I think it hits the seam of the belt. I wasn't expecting that with the Klingspor belts. I need to investigate that some more.

Make sure you're running them in the right direction. Easy to get them on backwards.

That's the first thing I checked. Had the belt in the correct direction.

Are the motors 220/110 voltage? I do have a large 220 to 110 transformer with plenty of capacity to run a 1/4 HP motor. It's like carrying a solid copper concrete block.

120VAC only.
