I have a project to make a revolver but I have some constraints.
I can neither weld or forge or do a lot of filing the frame due to my health so need to construct it with my old lathe and a cheap metal cutting bandsaw. So my design is compromised. What I have come up with is this.
Bore a hole into a 3 inch diameter bar which gives working clearance for the cylinder.
Thread the end with an internal thread say about 1/2 inch deep into the length of the tube then make a plug to screw into the end. I could then drill this to take the cylinder spindle and barrel.
My question is "What would be a sensible thread for the plug" ?
I am thinking along the lines of 12 TPI Whitworth mostly because I have two sets of Whitworth threading tools for my lathe.
The sides of the tube will be cut away leaving just a top and bottom strap except for the area around the threaded ends.
The steel being used is UK EN19T which is very similar to US 4140
The diameter of the threads will be about 1 3/4 to 2 inches.
Thanks for your help
