An 'Artillery' Nambu and Lahti

[sheepherder]

I'm using the rotary indexing head now. Cutting the front sight base, cutting the rear sight base major diameter. Very tedious work. 4º cut at a time. (One rev of the indexing crank).

I'm not happy having to set the indexing head & chuck on one end of the barrel and do my cutting at the other end. But there's no room behind the work table, and the indexing head only has right-hand crank.

Here's a sneak preview for all you lurkers...

Fresh out of the indexing head...No front sight blade yet; still mulling that over...have to check with Tom Heller on a blade...

I may narrow the rear sight base 'floor' as well...And chop about 3/32" off the muzzle...

But essentially, it's all roughed out!

Second pic is the barrel + sight mounted on the frame but one turn less than torqued...

I have a 'round' trigger guard coming, as well as another receiver; I'll take a pic with the round TG just for S&G...

Here I'm cutting the muzzle back 3/32", crowning, facing, and chamfering. Then it's on to the barrel vise. I had to stop and make a different vise insert, with a tapered hole, and modify my previous vise insert by milling 1 1/4" flats on the sides to fit the receiver. I put a 'notch' on the Nambu receiver to facilitate alignment. Finally, looking at the mounted barrel.

Still mulling over milling 'flutes' on the sides of the rear sight base. Front sight base has to be milled down .050" for the front sight blade, and a dovetail cut.
