Pulling the Race

Cut the head off of a C-clamp and welded on locking tabs. Huck of tubing from the scrap-bin sliced lengthwise, slotted for the locking tabs with a cut and ground 1“ Hilti bolt washer welded to one end. Another hunk of refuse tubing with set-screws as a sleeve to hold it all together.

* A piece of 4” steel channel as a base. * Two automobile connecting rods are then bolted to holes drilled in it at the right distance apart to suit whatever flywheels are being worked on. * A threaded insert was machined up so a half-inch or so bolt could be threaded threaded through, with locknuts to hold it in position. * The ends of the bolts are machined to a point same as a lathe center (60 degrees maybe?). * A magnetic dial gauge is stuck to the base to suit the job at hand. * This rig has been used to do countless numbers of 45 Flathead bottom ends, J models and big Brit singles like the Matchless wheels in the pic. * The alignment of the two center bolts is not super critical (they just provide the two points). The flywheels and shafts are a straight line between them.

Here is a pair of adaptors to swing big fat Harley 7) flywheels in a small lathe like a 4.5“ swing Myford etc.

Here is another way to true flywheels in a small Myford lathe that has only a 4.5” swing that won't fit Harley flywheels. Two offset pieces made from some flat half-inch thick bar and some half-inch round bar.
