It's great to know when I go to the woods with my Southern mountain rifle to deerhunt. It was made with quality machinery that I can count love your videals. They're very interesting. I ordered a Southern mountain rifle in 45 caliber, and 2024 cant wait to get it. Thanks again.
One day, I'm going to win the lottery and set up a home machine shop. I hope by then, you have patented this and are selling your tech to the public. I've watched many videos of the different rifling processes and this is absolutely phenomenonal ‼️ I would do this in a heartbeat if I could. Thank you so much ‼️
Very interesting video. I have a good friend who started making muzzleloaders as a teen in the 1940s (hobby only, not commercially). At the time there were no parts suppliers so he repurposed locks and trigger sets from junk rifles and made his own barrels and stocks. I'm going to show him this video the next time that I visit him. Using books from the library for reference he made a manual rifling jig like the ones used in the late 1700s/ early 1800s. It takes about 300 passes per groove; six grooves total so 32 passes is a great improvement. I am fortunate to have one of his rifles and it is a tack driver.
Hi, Nice to see your shop.. The screw assembly on the back end of the spindle to hold the barrel stable is called a " spider ".. Keep up the excellent work..
Your ingenuity and expertise is remarkable and your compassion with Little Dog shows. You would make a great employer or friend. I'm 83 not looking for job. Just totally impressed by you and your presentation. Bless you young man!
I was a toolmaker for 20 yrs and as such I’m impressed as hell . I did most of my work on conventional machines .I would have done things like making the rifling cutter .

Great work. Magnificent design and toolmaking. Does make one appreciate the work done in the past in designing such a machine to work entirely mechanically - and to do all the design on a drawing board and notepad!
@@kiblerjim Hi there, I saw your design for this knife last year, and it’s truly amazing! I haven’t had the time to pursue my hobby, so I haven’t been able to make it yet. I really love this design-it’s unique and innovative-and I’ve always dreamed of making such a knife myself. Is there any chance I could get the design drawings from you? I have great respect for your work, and I’m happy to comply with any conditions or costs. I hope to hear back from you! Thank you, and best wishes! 😊
You really nailed that rifling process using the CNC lathe. I’m a hobby machinist and have seen the single point rifling machines, located North of Milwaukee.. They pretty much do the same process. I learned machining by watching YT video’s. 👍
Wow. I just received a 1943 9" South Bend lathe with a 4.5' bed that my grandfather used to make barrels on. Huge difference from then and now. I also received a ton of tools and bits that I struggle to understand what they do but I know there were a lot more tools needed back then they do now. Cool stuff
@@rufustoad1 I understand… I thought you might have a channel. I have my eye on an old South Bend that’s been sitting in shop for about 25 years, waiting for the guy to decide to let it go… It has some different tooling I’ve never seen before. I think this lathe may have been used to make barrels. He has a number of sine bars, and the ratchet mechanism as well as the rack. I too am wondering what the rest of the tooling looks like so I can determine if it’s all there.
Very clever process you created, I'm impressed. It's great that with that lathe you have control over the C axis. I had no idea that was a feature on that model lathe. Thanks for sharing and posting the video.
Greetings Jim, Dave P here. A modern Innovative approach to a centuries old process, good on ye sir. Very interesting video demonstration to boot, enjoyed it. I hope your family, and business, are fairing well during this world wide pandemic.
This falls back to a design I saw in print that Pope used 50 - 60 years ago - but your re-engineering is just plain fantastic. I have an old rifle - and the only repair - is to roll the barrel from 0.312 to a standard 0.358 rifling. Thank you Sir - cheers
Great explanation and demonstration video. Thank you! I just saw a video with Brux Barrels. They are using Pratt & Whitney machines and their cycle time is around 30 minutes for a "standard" blank, 27"-ish? I'd say in your case using an adapted machine and blanks that are 30% longer, your cycle times are acceptable. The best barrels are lapped after rifling. You could consider lead lapping your barrels for an even more uniform finish. Great job!
Just a thought, instead of plugging the oil pump in, rig a switch neat the control box for easier operator access. If you trust relays, you could automate the oil pump from input from the control box. It depends on how much damage ensues from running the cutter dry. Thanks for showing us this fascinating process!
This is by far the most explanatory video I have come across yet about rifling head. Thanks! I would really like to get some more details of how you made the rifling head as I'm in the process of making one for myself. Pls advise. Thanks once again.
There are different ways to rifle a barrel. Cut riffling being one of the oldest. I don’t like button because the control of the lead is often a chicken and egg problem. The sexiest riffing machine has to be the Pratt Whitney model A sine bar. The model B got rid of the sine bar and has two gangs to speed things up. The hydraulics on the B are a nightmare as many specialized parts are obsolete. The model A downside is that uses turn of the century machine technology and was originally line shaft drive. Other makers of sine bars are basically copies of the Pratt Whitney. What you have done here is really impressive. Quality barrels are cut riffle barrels. I am not a fan of hammered barrels… originally designed for the German MG42 machine gun. It solves a problem unique to the MG42 but not on the radar for muzzleloaders. Marlins micro groove is a joke. I think fewer deeper lands are the way to go for long term reliability. While it would be nice to improve cycle time, you run the risk of breaking tooling and reducing quality. Cut riffling has always been time consuming. Personally I would accept it as a necessary evil and focus on quality. One of the proverbs from Solomon on haste comes to mind. I have searched for a model A for 20 years. After WE1, the anti gun mentality saw many scrapped and many exported to the Slavic countries. Model Bs were also scrapped in number after WW2. I have tinkered with idea of building a model A from scratch. The pattern work is insane and the bed casting is no easy machine problem requiring sending the bed around the country to get planed and ground. Older model As will likely need to be sent to Wisconsin for grinding as well. So what you have done is an impressive solution to a vexing problem. My hat is off to you on this one.
Amazing work, The only thing I don't like about the extreme care you put into your rifles. Is that it really makes me want to purchase one of your rifle kits. Boy this precision barrel work, along with some of that extra fancy Maple. Sure would be fun to finish up here in my shop. Just what I need. Another project. Cars and guns. That is where all my money seems to go. Keep up the great work. Hope you have a great Christmas. Hope your dog is still doing okay.
Back in the mid eighties I drove the Blue Ridge Parkway. There was a small building that housed a early rifling machine. Almost all of it was built out of wood. The technology is almost identical except for the accuracy and automation.
I would seek to add a multi point tool that free spins on the draw rod. This would be pulled through as a final stroke to remove the burr at each edge of both sides of each groove, and polish that corner uniformly. Of course, a couple rounds of hard lead ball would largely accomplish the same thing.... The tool could easily be created in a sintered metal process. Very cool process that can easily be changed for things like gain-twist rifling, 5R, etc... Awesome fix!
i didn't realize you were doing this,,, Great for you (and your customers)!! lots of benchrest smiths call that (cats paw) and outboard spider..probably a much more cost effective set up than purchase of a rifling machine??? indeed a very clever program/setup!! I have noticed quite a bit of difference in the quality of the finish inside different barrel manufacturers products... some look like railroad tracks,, some very slickly lapped..(competetion barrels being slickest) looked like it was cutting very smooth with no chatter!! from what one can see here,, yours looks great! you should get one of those cheap bore scope attachments to show the grooves up close (much cheaper than my hawkeye bore scope) . Good Job!!!

As a Machinist tool maker I Don,t Know if You Use a Diamond Wheel wet grinder for touch up the tool i have had best results using 1200 loaded up finishing wheel until the face is like a mirror it will cut longer without resharping also i try to use the hardest carbide i can find grade 5 i believe with a 4 to 6 degrees. Under the tip .010 wide and 10 degrees relief for oil cooling also you may try a chip breaker on top of the tool but its pretty small now and your asking it to do a lot may not be a good ideal . But as a swiss automatic and CNC-NC lathe machinist i know the steel and 4 to 6 will work and the blackest carbide mirrored finish no lines under 30x magnifcation More Cutting Less Sharping. Love The Video like the shop the dog and the music best of luck in all you do. Keith
This is a older video I know , just not long ago lost my dog Sassy of 15 years. They are joy in this old world and we are their whole world . Cherish thier time with us!
I like the way you are cutting on the lathe look real nice have you considered after you are done running a button through the barrel to finish it off this will give it a real nice finish no scotch brite needed save you time.
About the only Change I'd make is indicating the muzzle end using the spider adjusting screws. When I'm chambering I indicate both ends within .001. Excellent job. I think the z axis feed is fast enough, I might take a little shallower cut per pass. I put the indicator needle right into the muzzle.

As a Machinist tool maker I Don,t Know if You Use a Diamond Wheel wet grinder for touch up the tool i have had best results using 1200 loaded up finishing wheel until the face is like a mirror it will cut longer without resharping also i try to use the hardest carbide i can find grade 5 i believe with a 4 to 6 degrees. Under the tip .010 wide and 10 degrees relief for oil cooling also you may try a chip breaker on top of the tool but its pretty small now and your asking it to do a lot may not be a good ideal .
