I thought this might be of interest to some. I made a cylinder grinding device to make a seat for a ball bearing where a failed bearing ate a 1/2" groove in a 8 inch pivot shaft on a dozer. I welded the groove E-7014 above level with the shaft surface. This device worked well to reestablish the diameter. better description: 1/3hp ac motor with a 4" grinding wheel bolted to a 3/4" plywood just bigger than the motor base and lout to about an inch from the motor side of the wheel. I put a quality door hinge on the Wheel edge of this plywood. I used a second piece of plywood with the same size attached to the hinge. Under that I put 2 1X1" hardwood square "runners" parallel with the shaft, and far enough apart that the bottom plywood was almost touching the shaft to be ground. I put a wood wedge at the back edge of this setup between the wo plywood pieces to tilt the motor and grinding wheel downward against the shaft to be ground. I used a small vice grip to hold the two plywood pieces together against the wedge and two long hose clamps to hold the bottom plywood against the shaft Moderately tight to keep it from being loose, but allow rotation on the axis of the good part of the shaft. I also used a wheel dresser to taper the wheel to the approximate angle of the shaft surface. A cone shape at the outer edge. I hope this made sense. Jim

Many owners of tractors travel long distances to attend these shows and they usually take their restored iron along with them. Safe trailering practices and inspections will ensure that the event is a fun one. A good habit to develop when using a trailer is to give that �quick look over� before taking it on a trip.
