The Home Machinist!

I am in the process of restoring 2 Stevens Crack Shot rifles, both need relined. All the gunsmiths I talked to say to use JB Weld or epoxy to hold the liner in. Being a machinist I don't like that. What I would like to do is 'thermal shrink fit' the liner into the barrel. I have never done this befo...

I have tried that and didn't get the results I wanted. I need a close-up of the parts. I have most of the images off of the web including the Patten Office drawings.

Thanks for the effort.

My manual list it as direct drive, wrong manual or has someone changed the motor a...

The metal is non-magnetic and is as silver as aluminum. The pressure of the cylinder is 2500 psi and is held in place with a 71/4"-12 tpi thread, but this on the shaft end of the cylinder and never receives full pressure.. The old end cap is softer than the new one. I was hoping someone that de...

I have manufactured an end cap for a hydraulic cylinder from aluminum that is 7 inches in diameter. When I finished the project I noticed that the old end cap was about 11 pounds heavier than the aluminum one I made. Does anyone know what the original end cap could be? It is a white metal and very s...

My father worked there 30 years and I worked there for 10 years. If you would like a little history I can give you what I remember.
