FN49 Muzzle break updated info

[mountainman]

As of now, lets start over again. with teh offer from Gunplumber below I can sell these for $42 a pc which includes S&H. Any takers out there? This can fit FN49 or HK. I need to sell at least 15 so I can buy the lot of blanks. Come on Folks 922R part just like original at an unbeatable price.
Time to :sleep: Wake Up


Does $80 sound ridiculous for one of those? Made in USA and all. Also as in all my stuff hey can be bored out to any caliber. Some one asked me for one that was the price ai gave and they never answered. Just throw down your own .02 . Keep in mind if you have a problem with teh price you can always try this guy (http://cgi.ebay.com/Reduce-Recoil-With-A-Custom-Muzzle-Break-Compensator_W0QQitemZ260376040185QQcmdZViewItemQQp tZLH_DefaultDomain_0?hash=item3c9f9f12f9&_trksid=p3286.c0.m14&_trkparms=65%3A12%7C66%3A2%7C39%3A1%7C72%3A1205%7C 240%3A1318%7C301%3A0%7C293%3A1%7C294%3A50). BTW, you guys think I'd be getting in any trouble advertising on Egay?

I don't need one for an FN49, but I'd pay that for an original pattern (fishgill) brake for an SIG AMT, blued of course.

Got pics or drawings? got a way of getting dims?

I have a bunch of FN 49 not-yet-brakes from a project that never got finished - I took it over and still haven't finished.

They are internally threaded and externally profiled, but no slots yet, in the white. I just haven't come up with a cost-effective means of slitting them at the proper angle.

I sell them at 1 for $25, $6.50 ship, or $10 each in 10+ quantities. Maybe this is something you'd want to finish?

I see no point in making one that is not historically correct, but $80 for a correct one would be fair, albeit a limited market. 'Cause I know just how much work goes into small, non-CNC runs..

I don't see why you would but then again I'm against Gays getting married ...

the brake has nothing to do with "firing" the rifle ...

Maybe a gear tooth cutter? Not sure about the depth needed though. I know there are a lot of the cutters for stock profiles out there.

[gunplumber]

is that the same as a keyway cutter? That's the plan, i just wanted a indexable rotating table - as it is now, it would take far too long to set up the angle on each one. I thought about just doing them 90 degrees from centerline, but it would be so much icer to have them correctly angled upwards.

[L Haney]

Don't think they are the same as a keyway cutter. I ain't a machinist, but I've seen gears being cut. It is a tapered cut, think about the profile on one side of a gear tooth, or rather the space between teeth. Smaller at the bottom, opening out at the top. Lots of tooth profiles are standards, I'm thinking one or more may serve to give you the cut you're looking for.

[gunplumber]

like a broach?

Like these.

[gunplumber]

gotcha! Thanks for the info

[mountainman]

With a horizontal type set up and if the gear cutter could some how be made out of some kind of fancy cobalt or carbide with a ALTIN coating that would mean very efficient cutting on those slots. Now, the angle of those slots' width that you are talking about is not the only complicated thing. This is somewhat of a PITA
BTW, Gunplumber I am definately interested. I'd say that with Gunplumber's blanks I would be able to make these at about $40 a piece. Now to PM GP with a bunch of questions.

That looks like it was broached....not milled. Good for big production, not good for onesy twosey manufacturing.

some kind of female type broach where teh cutters are located inside of the V? Sounds very very $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$. I guess it would take about 1000 muzzle brakes just to pay that off.

[MR2 Zig]

I'm thinking that its a male broach with a lot of taper pushed from bottom to top?



or am I just reading that drawing wrong?....Wait a minute I am thinking the wrong way.

A horizontal mill with 6 cutters set apart the right distance. Make a set of aluminum vice jaws that you can use the wrench pin holes to index off of. That way you get one side of the brake in a pass. Or use one cutter and move across for each pass. You could use a ball end mill or make an arbor for the side cutter and do this on a vertical mill.


Put me on the list for wanting one.

[asg]

I'll take one for $42.

[mountainman]

Horizontal mill, now that sound affordable. and cost effective. Anywyas they will be $50 pc inlcuding S&H and I will send funds to GPG asap to get going.
