Bushing Hol der Flats | Grizzly T10668, T10667 specification

To use the floating reamer holder when cham- bering a gun barrel:

1.Set up the barrel in your lathe, per your nor- mal method, centering the bore of the barrel as accurately as possible.

2. Assemble the reamer (not included) and holder by inserting the reamer shank into the holder and tightening the set screws against the reamer flats with a 3mm hex wrench (see Figure 2).

3.Insert the round-nose dead center into your tailstock.

4.Apply an ample amount of cutting oil inside the barrel and on the cutting end of the ream- er.

Note: You will need to continue to provide enough cutting oil throughout the reaming process to ensure a clean cut and tool lon- gevity.

5.Carefully insert the reamer bushing into the bore while supporting the reamer holder in your hand, so the bushing does not bind.

Note: If the bushing binds, it might leave marks inside the barrel, so it is important that you carefully support the weight of the reamer in your hand while inserting the length of the bushing into the bore.

6. Move the tailstock forward until the rounded end of the dead center begins to enter the reamer holder (see Figure 3).

reamer holder using the tailstock.

7. Turn the lathe ON and slowly apply pressure, using the tailstock quill handwheel (after tailstock has been locked onto the bed).

8. Feed the reamer into the barrel bore and make cuts in short increments, stopping frequently to remove chips from inside the flutes.

We highly recommend that you remove the reamer every 0.020" to 0.050" and clean off the chips from both the reamer as well as the bore and re-oil before continuing.

Note: Galling in the chamber from chips packing in the flutes can tear the metal sur- face in the bore and create grooves in the chamber.

9. While stopping the lathe, slightly relieve the tailstock pressure. DO NOT pull the ream- er back before the spindle has completely stopped, as this could scar the chamber.

10. Continue repeating Steps 3–9until the ream- ing process is finished. For precise results, decrease cutting increments as you near the end of the chamber.
