[sheepherder]

Proceeding to the muzzle end...



9. Turning down the muzzle for the screw-on front sight band & blade.

10. Threading the muzzle to 1/2" x 28tpi.

11. A threaded block of steel fitted to the barrel muzzle.

12. Squaring the block to the bore.

Some more work to the barrel OD.



13. Cutting the taper to the exposed section of barrel.

14 & 15. Reaming the chamber. Clymer 9mm finishing chambering reamer, 1/32" at a time. Slow revolutions, oiling every 1/32", and blowing out the chips after every 1/32" cut.

16. Wups! A little out of sequence - Drilling the block of steel for the front sight band/blade.

More work on the front sight.



17. Tapping the front sight block 1/2" x 28tpi.

18. Relieving the sight block. Necessary because I can't thread right up against the barrel thread.

19. Milling down the sides of the sight.

20. Sight block is now mounted on a mandrel (old M16 barrel stub) and held in a 'superspacer' with a 4-jaw chuck. Circular milling the muzzle protrusion.

Still milling the front sight...



21. Just about halfway done...

22. Circumference of sight band is 98% completed.

23. Finish milling the muzzle protrusion.

24. Finish milling the circumference.

Had to stop operations on the barrel and make up a new barrel vise insert.



A. Facing each end of a 1 1/2" 6061 aluminum rod, and cutting a groove in one end.

B. Boring out the correct taper to fit this barrel.

C. Cutting the finished bored vise insert in two, and filing all edges.

Next up is to cut the front sight blade.
