The OD on my rifle barrel is 0.6720in ,so without turning the barrel down I can thread for 17x1mm right? What other options do I have? Because I don't even want to know how hard it will be to find a break with 17mm threads.
Muzzle threads ?

- Start date
I believe Brownells carries tooling that lets you turn and thread a barrel without having a lathe, but it won't be cheap. Simply sticking a threading die in a handle is not adequate because it is hard to keep the die coaxial with the barrel bore and the thread true. Most die threading is done with some kind of lathe to line the thing up well (look at the pipe threading machines at the plumbing supply stores). They are faster than single point threading, but less precise.
If I were you, I would stop looking at the threading operation as a way to save money and just take the gun to a gunsmith with a lathe. He can cut it to a standard thread size that brakes are available in or make an adapter, and that will open up a wider selection for you.

It's times like this I wish I had payed more attention in math class
As for having a smith do the work,the only one within 100 miles of where I live is not doing any work until late November. But If I have to go without my rifle for a month that's better than @#$%ing it up. When I threaded the barrels on my AK and SKS I found A die with a thread allignment tool to get the threads concentric,so hopefully I can do the same with this little project if I do decide to try it myself.

I'm not sure which is the most economical approach? I can't imagine a custom threaded brake will get to you much faster than the gunsmith can get to your rifle.

Why are you thinking of M17x1.0? You select the brake first based in part of the diameters available, then thread the barrel to the brake threads. Most of the muzzle brakes that seem suitable come with a 5/8x24 or 5/8x32 thread. 5/8 is .625", which would seem a reasonable amount to turn the barrel down. There is no way I would try this without a lathe. Period.
If there is no gunsmith in your area, any machine shop should be able to turn the barrel down and thread it. It is best if you can remove the barrel, as they would not be set up to handle a barrelled action.
I am inclined to agree with Harry, though, and wonder why you want a muzzle brake when you can't even spell it.
