Let's say I want to go into business manufacturing 6" barrels for a Glock 20 to shoot .40cal. What equipment do I need? Starting from scratch how do you make a barrel for a semi-auto, and what equipment is needed?
 
if you want to make only one or two of a kind then you would need a lathe and a milling machine. You would start with a barrel blank and start taking away metal. You would need a reamer for the chamber.

If you were to make lots then you would put money into building jigs to hold the barrel at different points in the machining/grinding processes. You would set up the machining process in order to do as little measuring as possible and still obtain the desired result.

I just bought a book on gunsmithing.... I think that would be a good first step for you too.
and a very good set of cailpers,a micrometer, a vise, a lathe, a milling machine, some magnifying glasses, headspace guages......

You would need to have a helical broach made too.As well as an oven for heat treating.
I dunno if the investment would be worth the return.
 
Also, if from scratch, you need a rifling set up. Then chamber reamers, a good mill (CNC preferred if you want any kind of volume), good lather (CNC again), cutters, a heat treating system and appropriate metal assessing equipment for after treatment, I think you can do without the broach though for G20 barrels. It would be a good deal of work, and time, and most certainly a LOT of $, think many tens of thousands for starters. I'm all for domestic manufacturers, I say go for it. :)
 
Go chat with our Cdn barrel makers to see what they can do for you in making blanks. From there, you can machine for final fit. I think that is the easiest way as rifling requires quite specialized equipment.

If the volume is large enough, then it is worth doing the import thing. Either finished barrels in bulk or blanks for final machining.

Personally, for what market there is in Canada, I would just go talk to a major US supplier, import a bunch at wholesale pricing and sell them. Unless you are making your own barrels within the expected market costs, you will face a hard sell.

There are a number of 'generic' barrel makers that do their stuff under the lable of a big boy. Maybe they will make for you under your lable is you meet their min.

Remember that making a gun part also requires liability insurance. That is very expensive.
