    I moved on from the flywheel jig to one I made from a piece of 1" x 3" bar stock. I drilled the base for the holding pins and bored a hole for the motor shafts. I cut a couple of pieces as long as the flywheels with rods are wide. I drilled two holes in each piece for set screws that will correspond with the center of each flywheel laying horizontal. Welded to the plate/bar stock, about 9" apart. I can hold the wheels with grade 8 bolts through the holes in the wheels and on the edge with the set screws. This holds the wheels really solid. I can also use this when I assemble the wheels.I can move the wheels around with the set screws and a wedge between the wheels sandwiched by the grade 8 bolts. When I put the wheels in the truing stand they are really close to good enough.

      If even more precise wheel clamping is wanted it would be easy to have the flanges milled or even surface ground. No clamp needed for surface grinding, just lay the channels on the magnetic chuck then match the flanges.

            If you don't need to save time you could get by with one indicator but two are much handier for this job vs. swapping and re-zeroing.

                  Spoke with him today...
                  Just as soon as the snow melts (He said where he lives at, there's 21 inches on the ground) he will let us know...

                  As of 2:00 pm this afternoon, MSHP has responded to:
                  • 3918 calls for service
                  • 1790 stranded motorists
                  • 878 crashes
                  • 57 injuries
                  * 4 fatalities

                  Nine people have been killed from the snowstorm that hit the central United States and moved on to the east coast. The deaths include one state trooper in Illinois working the scene of a snow-related accident. Missouri endured the worst of the storm, causing massive traffic problems resulting in 800 crashes injuring 57 and killing four, the state’s highway patrol reported.

                    You can bust 'em loose with an impact gun (preferably with a 6-point socket). No fixture needed for nut removal and beats fighting a cheater pipe on a breaker bar.
