I decided to do these steps on the Horizontal Mill, rather than mounting the frame on an angle plate and using the Millrite, because of the ease of setup. Since the Vernon Mill has a R-8 spindle, all the tooling is interchangeable. Travel in the Y axis is somewhat limited, especially when a drill chuck or boring head is installed, but sufficient to do the job at hand.
Here the centerline of the bore is determined. The dimension for boring the crankshaft bearings was then set. All the dials on the Vernon are very accurate, with very little backlash, so this was no problem
After drilling out to 1/2", the remainder of the bore was removed using a boring head. The top of the bearing caps were secuely fastened, to assure proper realignment after removal.
