I am looking to make a 9mm makarov barrel for my baby eagle. I would like to know your thoughts on the possibility of this and issues that I might run into. I would like suggestion on the material to use for the barrel and some input to make the tools I absolutely need that can be made. or where to buy tools that are more difficult to make. My first thought is to make a basic hand crank lathe and a spring loaded arm with a file attached to make the barrel round. The inside of the barrel would need some kind of inside cutter. Then I will need a cutter to rifle it. Not sure what is commercially available and what can be made. Any input on sizes of the inside of the barrel would be helpful also. I plan on putting a lot of time and care into this to get it to come out nice but I don't have a lot of money to spend on tools.
