Rifle Single Shot I THINK I Can Make This

[gitano]

I promised pictures of "chips" and here they are:
This is a 1.25" round bar mounted in the lathe and turned to 1.007" to match the breech diameter of the existing "Teutonic" Flobert.


This is the finished (turned) billet parted off and in my hand.


This is what happens when you THINK you have the work-piece held tightly in the soft jaws. No real harm done because damage was in area that is going to be milled away. However, since soft jaws clearly weren't going to work, I had to make some work-holding jaws.


The work-holding jaws being fabricated. They consists of two pieces of 1/2" aluminum clamped in the vise with a 3/4" piece of wood between them. (3/4" will be milled out of the round billet). Using a 1" mill, I milled/drilled down through the wood, but not out the bottom of the aluminum. That left a shelf for the work-piece to register against.


The work-holding jaws made.


Empty jaws before seating work-piece.


The billet in the work-holding jaws.


Milling 0.750x1.600 slot in the billet.


The milling finished.


A square 3/4" billet setting between the "wings" of the breech block.


This is a practice piece. Helps with determining proper order of operations, and things like "can't use soft jaws". Also, I haven't been "on the machines" for a long time, so this practice piece helps get back in the proper mindset for machine work. There's lots left to do with this breech block; drill firing pin hole, drill holes for screwing ears to "action", drill and tap firing pin retaining screw, round sharp edges, and "finish", but this is a pretty good start.
