Got back to work on the project.
Obtained a scrapped M-1 op rod piece. Really didn't want to cut up the full length repairable op rod I had. Needs a new piston head installed, but otherwise usable in an M-1.

Trimmed the broken end, made a mandrel to mount the op rod on so that it can be trimmed and turned to accept the new extension. Tight fit; op rod has to be tapped on and off the mandrel. Not all the way on in the photo.

The tubular extension was machined from a piece of rifle barrel. Will need to be plugged at the piston end. Will be silver brazed together.


Trial assembly.


Can't see why it won't work.
