Nut Boring

[Dean Romig]

These reamers, pack reamers and polishing fittings needed to have the drive rod centered within the bore - I know it was done with bushings but does anyone have an illustration of how these centering bushings were set up?

There were no bushings on any of the rods that the reamers threaded into. It was simply a long (36"ish) hollow shaft, roughly 1/2" dia, with a morse taper on one end, a stop collar that was positioned and held in place by a grub screw, and the tool end, threaded to accept the reamer. The only one that differed was the tapered reamer for .410. That reamer was an integral part of the rod.
