 | | Reamer - A Spiral Flute Shell Reamer, sized 1.125" but modified by turning down and re-shaping the front end (including re-grinding the front-end flutes) so that the cutter will now start in a hole that's about 0.975" or larger. |
 | | Reamer Pilot Shaft - Simply a 12" long, 3/8" drive, socket wrench extension, especially selected for OD of the shaft (0.474"), which is a very nice slip fit through the holes in the Reamer and the Pilot Bushing. |
 | | Now that our "piloted" reamer has cut a truly centered hole through the rear tower, that is exactly perpendicular to, and parallel with, the centerline of the bore in the actual upper, the next step is to tap the hole for the buffer tube. |
