Disappointed in Beaumont 10" contact wheel

When I built my GIB I was trying to keep the budget in check and went with the Grizzly 10" contact wheel. I machined it for bearings myself and did a pretty good job at maintaining concentricity and keeping lateral runout to a minimum. However I overshot the bore diameter on one side and ended up having to shim around the bearing. The wheel worked pretty nicely but, I was bothered by the fact that I had screwed up the machining and after several months I decided to buy a new 10" Beaumont wheel from USA Knifemaker. The Beaumont wheel produces an incredible amount of vibration on my machine. It seems to be machined true so it has most certainly got to be a balance issue. I tried grinding with it and it is just too much! Anyone have any idea where I might be able to get this wheel balanced?

I'm sorry to hear that Bob, I have the same issue with 12" wheel. The damn thing looks like a wobble dado blade in motion. After calling, I was told that the amount of runout noted, is "normal." Hopefully you have better luck in fixing this issue than I.
 
I contacted USA Knifemaker and they are going to take it back and have Beaumont send me another since they are out of stock. Hopefully it was just a fluke and I will get a high quality wheel to replace this one.

Sorry to hear that Bob... I know how frustrating it is when you think you're stepping up from something home-grown to a name brand item and it doesn't work as expected.



I have a 10" serrated wheel from Rob and it works beautifully, so I'd think it's like William said. :)
 
My 10"er from Beaumont I think so highly of I dont let any friends use it when at my shop. Definitely a fluke I think.

I was planning on getting one of the 10" Grizzly wheels and boring it for bearings as well. One thing you could do on yours to eliminate the slop in the one bearing slot is to indicate it carefully in your 4 jaw chuck and bore it out larger to accept a thin circular shim. Make the shim 50 thou or so out of 6061 or brass. Make it a tight press fit that will still allow your bearing to slide in without difficulty. You can then use some permanent Loctite when installing the shim.

If you are going to junk the Grizzly wheel maybe I could send you a little money for it and I will do the repairs. I need a 10" wheel.

Thanks,

I was actually considering boring out the entire bearing hub and pressing in a flanged steel hub that I could finish bore. It has been shimmed with .002" HT foil for months and worked pretty well. For right now, it is going back on my machine until I get a replacement from Beaumont.

The new wheel came today. It is much better than the other wheel. Runs nice and smooth up to max speed which is around 3600sfpm. USA Knifemaker treated me right and I appreciate that!
