Home Shop Rifling!

Homemade rifling? Yes it's possible! Once you get a nice hole drilled into a piece of steel, the rifling part is stupidly easy. Watch this video and learn how to drill and ream the hole, AND do the stupidly easy rifling part! Would you like to see more and better videos from me? Interesting content that you can't find anywhere else, and as always...safety third!! I'd appreciate your support on Patreon...some cool stuff coming up on my channel there soon! www.patreon.co...

I am a very accomplished machinist, (many shops, now own my own business), with several manufacturing degrees, and getting into airguns lately, I was thinking the rifling process, which I have never seen before, was a cutting process, but it is more like a burnishing/forming process. I never knew the button existed. I would have thought it would take a lot more pressure to push the button through. You can learn something every day and the day you think you know it all is the day you have a lot to learn. :)

[@markserbu]

Congrats and good luck with your business! There are actually 5 different ways to do rifling: Button, broach, hammer forge, single-point cut, and ECM. Button is the fastest and easiest and requires the least amount of up-front equipment costs.

[@brokeandtired]

@@markserbu crappy one could be fixed on a basic lathe as long as the hole was straight (even if angled) and steel blank was oversized compared to what is needed. Then just resquare the face and weld on the feed lip ramp or bolt it next to one.

[@CameronMcCreary]

I would like to see Mark make the rifling buttons and the broaches.

[@fuzzie567]

To EarthSurferUsa. Great idea for air gun to make it effective is the idea from the movie Cyborg with Jean Claude Van Damme where a paint ball gun with 20 to 24 ounce tank is converted into a manual revolver with either 4, 5 or 6 steel tube barrels and 3 indexed steel disc. The front end of paint ball gun resembles a Gatling Gun style look with choosing a 12 inch to 18 inch length of steel tube barrels to assemble all together with welding process to the 3 steel disc. For modified bullets you can make them out of 12L14 free machining steel. Taper the front end to a nice point of your choice of degree taper. Then keep the front of modified bullet solid while the back of bullet will be hollowed out for the air to project it from the barrels. Imagine the psi pushing out those 12L14 steel bullets from those paint ball gun tanks compared to those small Co2 that you put in a pellet gun. Then you can test that baby out on some pine wood slabs and fire away and enjoy. 😁

Thank you Mark. I'm looking forward to the next installment(s). The idea of making a rifling button for yourself from (relatively) commonly available materials sounds very interesting. Machining and those types of processes have fascinated me since I was a kid, and yes, my Jr. High school and High School both had "real" shop classes where we used real industrial machinery. In Grade 7 we were turning, boring, threading, knurling, milling and (using a shaper) flattening real metal parts. I feel very sorry for kids in school today - wrapping them in cotton wool does them no favours.

Take out 2 opposing screws from your vice jaws to get that pocket you were talking about. For that button, put a socket on the end with the square end against the barrel and press the button into the socket to get it the rest of the way out. This was a cool video. I like your style because you know better and you explain that and what's the right way and what works. Looking forward to learning how to make my own rifling button.

[@MajorButtons]

fun fact: those agressive tooth'ed pads on a vise are held on with screws because they're made to be reversible. there is a toothed side, and the other side is smooth for when you don't want to put a texture on your workpiece.

[@jdog4534]

I thought the same thing until I tried it a couple weeks ago. The holes on the other side aren't countersunk for the screw heads. ..and I had to use my impact driver to bust them loose.

[@jimandaubz]

Not quite, but close. You can countersink the reverse side if you want, or buy a set of soft jaws for a few dollars. Personally I think buying (or making) the soft jaws so cheaper since your about to ruin a counter sink if you choose to make reversible jaws

[@jimandaubz]

Watched to see your process for rifling. (15 years in aerospace, and theres always something to learn, thank you for the video, I don't think I am sharing anything you don't know, but I think this would be useful for the average viewer) A few tips I have picked up. Reaming with hand tools works better then tightly constrained, more flex in your tool holding set up the better so it can guide itself to the average and the less it binds, but you do need to use a reamer made for hand tools to fully utilize this, and make sure you have at least .005 (inch) to remove, and not more then .007 ~ish per inch on hole diameter. And of course ypu need to use the guiding brushing thay goes in the little hole in the end, they are sold separately. In my experience, always refer to the machinist bible, don't trust a random commenter experience haha. I have used this principle to fix holes that where undersized on 1/4 million dollar jigs, saved the entire assembly after it was welded and too big to fit in our football field sized milling machine. I got a raise for my efforts so I am more then happy with my results. They where within +/-.0001 and the tolorance was -.0002 +.0001. Takes practice to get excellent results, if I had not been the general purpose "fixer" in the shop thanks to my hand techniques and flexibility I would not have pulled that off, but I think a garage shop could figure it out with a dozen or so practice holes. Some tips for getting a through hole centered and straight, drill out with an undersized drill first. Drill from both sides first, and dwell when your at the bottom, size up through three drill bits if you can but use at least two. Only the first needs to be drilled from both sides. Again, it was really awesome to learn from your experience in rifling, I will utilize it well, I am surprised that buttons do not require a twisting punch to push through, that was cool to see, I would like to know if you have tested for drunken twist?

[@rayherriott6517]

One thing not mentioned - after the button is pushed through there are very high hoop stresses in the material. The material needs to be stress relieved before machining. Also important is the material properties, ie: hardness. Typically barrel material is between 28 and 32 Rockwell C when drilled, reamed and rifled. Then it needs stress relieving before machining. Materials of lesser strength will not stand up to anything much over .22LR.

[@dennisyoung4631]

Sounds like 4140 pre-hard, or, perhaps “ETD-150” - a free-machining flavor of the same… (Just got done turning stub-axles of the same for a bike trailer. Pressed and pinned into an .058 thick tube of 3/4 4130 tubing…)

[@Parents_of_Twins]

Stainless is a fairly common rifle barrel material does it fall in this range? I've got 6-8' of 1.5-2" stainless I was thinking about using to make a barrel. Might have some other stuff as well not sure. Bought a bunch of metal a couple years ago and have been working on figuring out how to get it home since. I just finished rebuilding the engine on a rough terrain forklift that I'm planning on using. I know one pies as 6-8" in diameter and at least 6' long and there is are other pieces like that hence the forklift. It's all in behind a guy's house and it's soft back there as well and he doesn't want his yard torn up which is why it has taken so long, think it's between 3-4 tons in total.

To get a perfectly centered hole you need to spin both the part and drill bit...although your method of doing this in a home shop with limited tools is very good. Nice job

Maybe someone already said, but what I do for a better "center drill", i use the method of I need to remove a broken off fastener down in a hole. But still a hole in a block of wood near the same outer diameter of the would be barrel. Drill with a press, then lower the drilled block. Place would be barrel in hole, hold with vise grips or whatever you choose, the drilled holes in the block will hold the barrel in alignment. While holding the barrel with grips, drill the smaller home in the barrel. That will give you a MUCH better aligned hole.

You can get thinner cut off wheels for your cutoff tool. I worked in the Plastics injection molding industry for 21 years and Still have a few ejector pins never bought any though. The really thin ones can be ground to a fine point and used like a needle. You can also make firing pins with them. Over the years I built a few barrels without rifling for .22 blank perimeter alarms. Used the ejector pins as the firing pin. I would cut a small groove in ejector pin on the lathe to hold my clip, and then turn down part of the head of the pin and make the firing tip. That way I could insert a spring in the tube and then my ejector pin. I would make a screw on tip that the blank would fit in and threaded up into the tube. Had quite a bit of fun with them. Mine wasn't fancy or anything ,but were useful. And the blanks I used were actually store bought for a nail gun.

Get a $12 dial indicator and those telescoping clamps, I think that's what they're called. It's a couple of rods and some hardware that allows you to clamp the dial indicator to the spindle of your drill press and position it wherever you need, to check the squareness to the table in the two axis that you need to drill that hole strait. That cost about $20. You simply position the dial indicator perpendicular to the table and rotate the spindle, watching for where the needle moves. Look up "tramming a mill", this will show you what you need to know. Also, besides never reaming with a hand drill, you really shouldn't use a reamer to make a hole that small 5 thousandths bigger. That's too much. ... ... ...also, next time you use a vice to push a rifling button, at least put a flat piece of steel on the skinny side so you have a better chance of keeping it strait, those jaws look like they're hindering that. I've taken two tours now, of places that make high end barrels and they say that the biggest issue is keeping the button and rod as strait as possible. Well, theirs looks like the button & rod are one piece but the same rule applies. ...ha, I see you caught that towards the end, a flat piece of steal wouldn't be nothin to just add to the mix. ...waite you have a mill!?! what the hell are you doing, man? lol crazy bastard!

Looking forward to the rifling button video. I just finished putting the GB-22 drawings into my cad/cam software. Material arrived yesterday so my build will commence as soon as a machine opens up.

As a fledgling machinist this video was absolutely hilarious; the idea of defying every traditional do and don't. What REALLY got me was the "dog wiener buckling tendency" @ 17:57 in the video. Hahahahaha.

Hardly anyone sees that! Every single web page screen shot has an "unusual" search term on it. ;-)

If you take two vice grip pliers weld one to one tooth big vice and other side just have one part movable so the little vices will hold the subject stable while strengthen the hole you're a genius
