I found this homemade rifling bench on utube. Of all the rifling benches I've looked at and all the plain I've seen....this is the ONE!! Anybody can make ,and will work the same, Every time!!! So take a look.I'm sorry but I don't know how to do the right attachment, just do a search on utube. The title name is "muzzleloader barrel rifling bench", and the video is by "lastkingopoland". Maybe if some (who know how to post the link) look at it they can post the link, the right way. IF YOU EVER WANTED TO RIFLE A BLANK BARREL THIS IS THE MANCHINE!! The first time I seen it I just shook my head.....too easy...how come I didn't think of that. Somtimes life is too easy.:dancingbanana:
 
That's a slick home setup. Thanks for the information.

Here's the high tech version that uses the same principle.

And an animation that uses the same "sine bar" along with a rack and pinion as well as an auto indexing cutter wedge.

Seems like there's a few ways to do the same thing as long as one can get a good quality rack and pinion gear that's suitable.

With all these examples of how the basics work it should be possible to work out how to build one within the abilities of most home workshops.
 
Does any one have access to a rack and pinion that would work? That is a great design and doing it by hand negates having a complicated drive system. Guy runs it by feel and adjusts as necessary. I have always been intrigued with the idea of making a rifle from raw steel. I think the really hard part is drilling and reaming the barrel, or am I wrong?
 
.
There was a video and information (cost about $135), made by Bill Holmes and distributed (I think) by Wolfe Publishing Company, that gave all the details of making a rifling machine. In the video, Holmes shows how to obtain the parts, build, and use the home made machine, including drilling and reaming the barrels.

There is the Bill Webb rifling machine. Do a google.
For rifling a muzzleloading barrel, the absolute easiest guide is another barrel. A slug is cast on the rod, and is turned by the rifling in the guide barrel.
There is also a method where a square steel rod is twisted. This passes through a square hole, causing it to rotate.

Not wrong. Deep hole drilling is a bit of a science in it's own right.

Look online for "Gear Suppliers" or "Gear manufacturers". Lots out there. Essentially you sit down and sort out the diameter of the gear you need, and the tooth count. With that, you can determine the Module (mod, metric)or Diametrical pitch (DP, inch dimension) and use that info to order a section of rack (which is simply a straight section of gear teeth).

The dimensions of those will dictate your dimensions for the remaining portions as the gears must mesh correctly, else there will be issues of binding if too tight or excess lash if too loose.

He said in the video that it was a 28 tooth gear.

Have fun! Looks like a pretty straightforward, bare bones sine bar rifling machine.

Good picture showing relevant dimensions here http://www.cogmatic.com/racks-pinions-2/

you can buy steel bars with holes in them already

just find the size you need, and ream it yourself. you can buy reamers, or make your own.

I have a book by a muzzleloader builder who makes his reamers from hacksaw blades.
but adjustable reamers should work better.

I have a bar with a hole that some day I hope to make it into a 63cal muzzleloader barrel, it is 1" outside with around 0.220 thick walls

for a high powered rifle, I would look for better steel than I have for this, or buy a used heavy barrel and go from there.

Every front wheel drive car made has a rack and pinion (steering). Or at least most will....you don't need a 28 to what ever he is using . Just would have to be a number that would divide into what ever the amount of rifling groves you are cutting. The point I was trying to make is , this is a homemade rifling machine that anyone can build and uses. Anytime I find something as simple a design as this, I just shake my head. I've looked at a lot of rifling machine, lathe mounted (homemade) to big logs with groves cut into them. This little machine just makes me smile.
And as far as a blank barrel...the only thing I could think of ( next to buying a factory made boring machine) was to buy an old surplus barrel of smaller size and just re bore it with a centering drill bit and ream. When we sit and wait for a barrel blank from the US or somewhere else....will it show up ...or will it get return to sender.
The ability to build our own barrel or what ever is sometimes more fun and fulfilling. It will not be the best rifling job in the world...but then again it just might!!

You don't even need a pinion that's divisible by the number of grooves. You just need a long enough rack to make your twist. You would want to index the headstock by the number of grooves though. A gear could be used for the indexing in which case it would need to be divisible by the number of grooves. You could also just use a hole plate which is easy enough to make on a rotary table.
 
Yeah, the use of a 28 tooth gear on a section of rack is a pretty elegant solution to solve the problem though.

At the end of the day, it pretty much boils down to whether you can scrounge up something useful, or if you end up buying the gear and rack (cheap, for the problems it prevents you having to solve).

When I was a machining apprentice I built a muzzleloader. Built a split spiral tube for the rod with my carbide button and just clamped it down on each of the 6 flats to index it. In my Younger days I ended up turfing it thinking it was worth nothing. Probably cause of how many times I was told it was worth nothing. Now I'm old enough to know not all value is captured monitarrily. I think if I still had her at this stage in my life she'd be the pride of my collection. I benched nothing back then. Having said that I could have hit a hockey puck at 50 all day long with er and a patched ball. Geesus I wish I wouldn't have thought of her, now I miss er. She was probably the first stainless ML
 
Forgin', deep drillin' and riflin' and fittin' the rifle the 'ole way... only the first part of it...

 
Baribal know that's some cool videos !! That's the kind of "look backs" that are great to learn from. No cnc's , home made drill bits, home made reamer...cool way cool! Thanks for the info!! :)

Amazing show... I just watched all the parts (10 in all). Really enjoyable to see things done by hand... 300 hrs total to build a flintlock - Wow!
 
Mr Gussler (Wallace Gussler, the Master Gunsmith) is still in business and have shown many people since then how to make real guns :)
