Rice Barrel Co. demonstrates muzzleloading barrel rifling on a NMLRA machine 

I help a guy use one of these machines occasionally. Actually the barrel stays locked down in the same position all the time. There is a indexing feature that moves the cutting rod to the exact next place where a groove will be. The idea is not to cut each groove in its entirety at once but to initially establish each groove and slowly deepen each one. It usually takes around 300 or more for each groove. It is imperative to count the strokes so all grooves will be close to equal. When the cutter stops cutting you lift it out of its groove and put a paper shim under it to deepen the cut. When the paper shim is installed the first pull stroke is sort of hard to get started. We use crisco or lard for cutting oil as the chips stick to it good.

There are two videos on my channel showing one of these in operation

The barrel is octagonal , 8 flats, and remains in the same position, it is the cutter that indexes.

How difficult would you say the process of building it is? I have machining and welding experience but zero wood working skills

Or the guy behind the camera, there several thousand strokes. 8 grooves say a hundred strokes each. Can't these guys add up. I believe what you said would be closer to the mark.

Mr.leatherbark....Sir do you know Where i can get this machine..? Thank you sir.

Sir can I Link your chanel.... I always volved antique blackpowder rifles...¡¡¡¡

@@diegosuarez1265 This rifling bench is homemade. You should be able to find a booklet on the internet on home made riflling machines. Thanks for watching.

@@Leatherbark thank you again Sr. .....thank very much...¡¡¡¡

Machine is located at the NMLRA education building. No plans available that I know of.

@@rickweber7157 .....thank you Very much....thank.....¡¡¡¡ I'll se what can you sir.. ¡¡¡¡

There is a book printed that has all plans and information on building this machine.

There is a gunsmith in Colonial Williamsburg, Virginia who demonstrates how they made muzzle loaders and barrels and rifling with this same set up. IT IS NOT CHEAP to get a rifle made this way

@@thomasburkett6417 but you would feel it's a "real" rifle.

That they are

It would not be cheap. You need to understand these weapons are handmande, the guy has to work from pieces of metal and work some 300 hours into having an finished gun. If you just want to shoot an relatively accurate replica you are better of getting an pedersoli.

Drill it out a bit bigger than the bore, thread it and use a threaded breach plug. You make it bigger so that it fully seals the end and doesn’t leave the threads exposed to the bore / explosion

This is an example of an old design. Yes, that could make it easier and faster, but it'd lose the actual purpose of this one. Tradition and simplicity. I mean, they could just go and use a CNC machine to do this instead and it'd be incredibly easier. But that's just not the point.

Because it would need too much force to pull and also too much force to force the tool into it's rotational movement. Such long rod that holds the tool can not withstand too much torque force without give in. It acts like a spring then.

It is only wood after all

@@epion660 no,cnc has some limition.too expensive and may not long enough to cut very long barrel. use wood make it easy and cheap

make multiple grooves first too hard to pull .second hard to make all the grooves same shape.

@@timlewis2068 TROLLSKY!

So true haha

I don’t think you can make a spear on that machine, but I could be wrong

Lol maybe South Africa or Rhodesia
