Need help on balancing a felt buffing wheel

[Kevin Wilkins]

I ust got hold of a buffer similiar to a Baldor - 750 watt motor with a shaft on either end . Shaft dia. is 15mm ( about 5/8 inch). I have tapered spindles that are held on with set screws to allow simply runing a sewn buff on and polishing away. That works fine.

I recently bought 2 felt wheels with a dia. of 10 inches which are pre-punched to go on the tapered spindles, but they vibrate so bad the machine seems like it's gonna fly apart. I can enlage the hole in the felt wheels and attach them to the shaft - without the tapered spindles - with spacers and nut, but my queston is: Do I need to balance these felt wheels? I'd hate to ruin the machine...

Thanks for any advice in advance!

The tapers might be off set a little causing the wobble.

If the tapers are ok I would take a tool like a wood workers chisel and true up the felt wheel while it is running. This should balance it.

Another alternative is that the bearings need replacing, I would check this first.

Hi George,

looks like you were right about the tapers. With those heavy 10 inch felt wheels even the slight amount of imbalance caused the problem.

I enlarged the holes in the wheels so that I can mount then directly on the shaft and bolt 'em in place and they turn fine. I just have to fabricate a small spacer.

Thanks for your help! What would I do without my internet friends? Probobly make a lot more mistakes and waste a lot more time than I already do...
