Re: SUCCESS
Well, I tried to apply my buddies grinding methods to make my "Big Wheel" actually round.. I'm sure he'll cringe at my methods, but they worked. I clamped my right-angle grinder in my vise and then turned the face of the 'Big-Wheel' against the spinning 4" grinder wheel. I started in the middle of the tread and then tapped the entire machine slightly sideways until I reached the edge of the tread. Then starting in the middle again I tapped the machine in the other direction until the entire tires surface was reground. Holy SMOKES!!! I couldn't see from one side of the shop to the other and the whole shop looked like the vulcanizing area at a Uniroyal factory! Everything was black, including me!
I finished up by cradling a orbital sander in the vise and spinning the 'Big-Wheel' against it while the sander was running to smooth out any minor holidays.
What a difference! The grinder runs much smoother, can be operated at higher speeds and is a pleasure to grind on!! Now I have to rebuild and improve my idler/tensioner/adjustor mechanism and replace my home made wheel with a skateboard wheel. The bearings I used just can't take turning at those higher RPM's.
What a great tool! Keeps your work piece much cooler than smaller stone grinding wheels and the belts come in a wide variety of grits.
Hope you guys all have a fine Navy Day...
