![Can 3D Printing Fix This Tormek Problem? [WM200 AngleMaster] #knifesharpening](http://i.ytimg.com/vi/Dssrae5kcKw/mqdefault.jpg)
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. :)
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.
@@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.
I would like to see Mark make the rifling buttons and the broaches.
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. 😁
I went from rc’s to airguns as well, most of your high end airguns use lother walther hammer forged barrels.
Yup, all 10 fingers. (Or to be technical, 8 fingers and 2 thumbs.) You must have some amazing surgeons in that part of the world.
My grandfather used to make the barrels/ rifling for the Australian Owen gun in ww2. He then went on to make gear boxes, obviously loved precision.
Was he of German,Japanese or Croatian descent?!
@@maxluburic657 English/ Australian
@WrathMachine no mate rifling they used to pre drill then rifle it but the American's came over and said put the rifling bit straight through. Thanks for putting my late grandfather down he also used to make gearboxes owned his own company that made us well off, each to there own.
@WrathMachine what ever mate your technical manuals must be different, we used to have barrels kicking around but they are gone now, so I guess I have to take your word for it.
@WrathMachine gee he lived to 90 and died 10 years ago my father said as a kid he played with a non working owen that was rejected, maybe it had rifling when it shouldn't have anyway who makes a subbie without rifling I haven't found any information to prove your accusations, a name of a book would be handy but he made 500 barrels a month on a lathe. A 9mm without rifling who would have thought.
I started rifling my own barrel when I was 14... and you are right.... it is a rewarding experience.
It makes me happy to see I'm not the only one that has a problem drilling straight holes :)...
I was thinking that lathing the work piece now using the hole ends as the new centers might probably right the whole thing.
@@FourSeasonsHD that's a process called "turning between centers". You are correct, that would true the outer diameter to the inner diameter. Afterwards you would have to face both ends though because they would be running out
I nearly always drill straight holes. Drilling them in the right direction, however, is another story
the Idahoan, makes rifled pistol barrels with a press and home made bit. He didn't fire and quench it, but it worked fine
I feel like, ...like, you're sending microagressions. To anyone whom it may hurt. Yeah.✨🤣🤸
If he didn't do that the barrel will wear out really quick due to it not being hardened.
That was just great. I like how you compared the “Southern Engineering” method to having precision machines. Keep up the great work and thank you for sharing your hard-won skills.
After watching the video of the BFG-50A on Forgotten Weapons, then seeing this, it gives a great perspective of what you must have gone through to create it. Thanks for showing this process!
I watched the bfg 20 year history today then this popped up
I love how Mr Serbu seems cynical of the shit you have to go through to make stuff if lacking in resources, but at the same time, talk about how theres a lot of possibilities. "You can just do this holding in one hand and filing with one hand". This man, true engineer.
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.
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.
That would be fun asf, if I had an option like that I'd probably want to go to school ... :\
Great that you showed the failings and problems that you ran into along the way.
Thanks for this.
Half of me is like "YAH! you can do anything and don't have to have expensive tools!" and the other perfectionist half is like "WTF are you doing?????" lol
If I didn’t know who Mark Serbu is, this video wouldn’t be nearly as fascinating.
sir , if u call this crappy u r underestimatin ur effort , it willl definetly deliver bulllets to their targets , you have given a glimpse , we in third world appreciate u r understanding and application, it is very genuine and of higher order.
Thank you. Perspective makes a big difference, doesn't it? Here in the U.S. we can just buy barrels but in much of the world they're very hard to come by!
I was already giving up on making my own black powder gun, but watching your video I think I can. Thanks.
Lathe works the best....been there done this......aaannnd CNC's rock...you can make these for your friends and family. Pass em out at Christmas and family reunions.

Im a mech engineer, formerly a cnc machinest, iron worker, classic euro car performance shop do-it-all,the literal real life macguyver. and according to my s.o. the fixer of all things. I do it well. Very very well. I waited all the way through to comment here. This was a great example of how this works. I see a bunch of comments saying they are a machinest etc blah blah. Also a firearm enthusiast. Most everything in the safe was built by yours truly. Lotta people haven't seen this ever let alone have a rifling button. Here fellas. This is concept and explanation. Would I ever fire that? Hard nope. This is a GREAT illustration of the concept and an illustrative example of how rifling (mostly) works. At the end of this, mark has accomplished many things we have not. Harbor freight is my jam. Prominent media personalities showcased Cars I built using quite a few HF tools🤣 knowing what your doing cannot be replaced by tools a home mortgage is equal to to fill a single toolbox. (To an extent) this shows you. Yes, it's possible. Not ideal unless your the kind of person with hundreds of thousands of dollars of high level machinery. If you know what your doing, BET your ass this can work🤣 I love it Mark. Diy, basic and cheap tools Because that's what everyone realistically is going to be working with. It's a gem buddy I love doing more with less
Health and safety must be having a fit watching this! BUT WHAT A GREAT VIDEO and it's a good reminder to all of us about ..the things we all do wrong in the workshop
"These calipers are messed up..."
Literally my experience with every set of calipers.
It helps to know the correct way to use "PRECISION INSTRUMENTS", they're not hand tools for idiots.
@@ronald209
I've always wondered why the threads on these little Mitutoyo C-clamps are so fine, with graduated markings.😂
@@ronald209 my own calipers are fine after 4 years
Every other set i get a hold of aside from brand new ones though....
Every set at my machine school is messed up aside from the teachers. It's fixable but we're not supposed to adjust them
@@ronald209 helps if you don't use them as a scribe or over tighten them while trying to gauge a piece.
Made a video full of... What NOT to do!! Love it. This is how we learn.
😂Always comes down to a hammer... and beating on it!! My skill set.
Ream it after you drill it, while it’s still on the drill press locked in the vice. Cutting oil really helps 😊
Lol
👏👏
honestly love this, just brute forcing everything with the cheapest tools possible. though crude, its very good information. more entertaining than watching a cnc machine spit out parts in 5 minutes.

Watching stuff like this, gets the gears moving in my head.....this caint end well...lol. thanx Mark love the vid
Hope ya all fared well thru Irma
You build some awesome guns but everything about this video is sketchy as shit. Which means I can for sure do it at home!
bucketsof lead Ata boy! Love that spirit!
That sort of seems like the center of the stock. (bunch of scribbles that don't come to anything resembling a point) Good enough, whatevah. It don't mattah, none a dis mattahs.
@@HaqqAttak the center is the area that appears in the middle of all the marks.
Machining is usually a little more precise than that squid.
On this particular part, the OD will be turned while it's held between centers. That means the location of the hole doesn't matter a bit, as long as it's not so far off that the OD won't clean up.
In my experience, to drill a hole through the center of round material, I put the drill bit in the vice on the drill press and the material to be drilled in the chuck on the drill itself, it will drill the hole dead center every time, no special tools, lathe, etc, just go slowly an flush with lubrication and voila! A perfect, centered hole in your round stock, with the right chuck on your drill press, you can drill octagon or hex stock just the same, hope this makes sense, it works like a charm, db
This guy is awesome. This is called thinking outside the box and it's very inspirational for educational purposes. Thanks
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.
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.
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
I'm so glad to see that this step is simpler than I have been making it. Now if I can just make a rifling button that won't deform in the blank...
I've decided that this will be my school science project next week
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?
Mark you're the most self deprecating craftsman ever hahaha... you remind me of a more advanced version of myself.
Thanks for setting up Edwin. That guy is hilarious.
Just awesome someone has taken the time to show home builders how to do so.
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.
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…)
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.
love what you're doing with these vids Mark!
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
This operation is typically done on a metal lathe where the workpiece is chucked in the headstock and rotated against a stationary bit chucked in the tailstock; only one part, tool or work, needs to rotate.
This video is so awesome! Thank you for doing it the "quick and dirty" way of doing it, because you proved that you can Macgyver a gun out of nothing to protect yourself from the ever present criminal element that's out there ! Thank you again, sir. You got a viewer from now on !

I did one barrel here in australia(supid gun laws)i spent 8 hours driving a 9mm button down a stainless barrel with a hammer n rod
It worked perfectly
It was a 500mm barrel
A guy was done last year in Western Australia for making barrels (and the rest of various sub machine guns). The judge accepted it was a case of collectors curiosity but warned that it was very serious and wouldn’t be tolerated again, then let him off but now that his zero tolerance stance has been noted in the judgement I don’t think anyone else will be so lucky
next video : how to make Apollo 666 from the shoe box and 3 yards of duck tape
that subtle jab at royalnonesuch was spot on :p
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. ;-)
I’m watching this video after a few beers. Enjoying it, didn’t catch who made the video. About 3/4 of the way through I’m thinking to myself, this guys voice sounds very familiar. Then I think this guys sure sounds a lot like Serbu. Then I check who makes it. Lol. He’s a one of a kind. Good stuff
You keep on saying what I’m not supposed to do but you keep on going. I’m glad you did. It’s fun to see homemade gun parts. I just love it
Watching you wrangle that death wheel had me puckering.
It's ok...I'm a professional. ;-)
I have watched probably tens of thousands of UA-cam videos and this is by far the best one the best edited one that I've ever seen! Extremely informational especially whenever you pull up the Harbor freight's and whatever other place you buy them from most guys simply don't say a damn thing is completely quiet which I think is hilarious. Great job dude
I just found this video and man, I hope your Safety Squints were in "angle grinder" mode for this project!
Loved it.
"....spin it between a couple of nails and grind it...." HAHAHA
I just might have to actually try that one day to prove that it can be done, because the theory is sound.
I've used a drill press and nails as a poor man's lathe and live centers... It worked. Not well.
Love these types of vids! Especially from someone who has the skills and machines you do. Salt of the earth regular guy stuff but still very informative. Keep it up!
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.
Thanks Mark love the simple way you rifled that barrel!
This was a osha night mare lol loved it. Safety Sally's somewhere were screaming.
If you ever get fired from a shop, and you want to get even, sick osha on them with complaints that you know are true violations, (and every shop has them).
I wish I could have seen the look on the bosses faces when they found out it was me. They thought they hired an amateur and tried running me through their boot camp routine. I didn't take it, I got fired, and they got burned. :) Safety Sally? Before my time I guess, but sounds like your other Mother. That is government for you, treating grown adults, (who pay for their existence), like elementary kids, when they aren't adult/functional enough to make a dime in our free market. Is there a Safety Sally coloring book too?
@@EarthSurferUSA We had a disgruntled employee do that to us once. Luckily we don't have enough employees for OSHA to have jurisdiction over us.

Man, I absolutely love your style :-D This reminds me of the sketchier things I've done with the press. Would have been nice to see it rounded off with a pipe cap breech so you could bring things to a close by popping off a .22
Really interesting to see the bare minimum approach. The quiet metal playing throughout in the background is a nice touch too, that's what my shop would sound like.
Build is going good, starting drillling and reaming today on a handful. Rewatched the video today and noticed the search terms this time. roflol
Holy crap. Rifling a gun barrel on your own. I realize it’s harder than it looks but it can be done is what you’ve shown. I’m just smiling and scratching my head. Thanks for passing on this knowledge. Seriously
Why not simply by different sizes of barrel liners? They're made to re-do a worn-out barrel, . . . Ream the barrel; heat the barrel; chill the liner; and slip it in, . . . or, for no heat, ream close, and red Loctite, . . .
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.
Thanks Mark, you've unlocked the secret to home barrel rifling. I'm old school just like you....
It's fun. That's why we do things like this ☺️.

Edwin 👍 Glad to see you here Man
Funny thing watching this when Mark is pushing the button through completely with the vice, say how things could shatter. All while holding it with his hand. *Then I notice all the scares on his fingers and knuckles. Telling me this man knows this could shatter from first hand experience!* Pun intended.🤣😂
Great job actually. Love the fact you show how an average Joe could accomplish this in his shop or basement.
Thanks Mark!
By the way, I really like this, it is so much fun, to see you working, cant wait to see part two, hooo, hooooo !
Glad to know it’s possible to do it on a budget, I’ve wanted to make a .22 break action pistol out of some railroad spikes I have but rifling was keeping me from it. Now that that’s not holding me back and I have access to a lathe and mill I can probably have the whole thing finished in a few months.
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!
You are really clever I liked your way of thinking thank you
Just what I wanted to learn, thanks for sharing your knowledge Serbro
Thanks for doing it with simple tools. And, thank you for showing us the right way!
A very wise old machinist I apprenticed under once gave me a piece of sage advice " any problem in life can be solved with the proper application of either pressure, lubricant,or both."...I guess it does apply to gunsmithing as well
Now say that line with a twist, just like how Rodney Dangerfield would've.

Dude your my hero I can’t find 22barrel liner no where your video is a great help
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.
Short and sweet. But what about long barrel? Got Gun Drill machine?
Nice shop you have there. I hope to expand into aluminum billet parts, and get a Haas or two also.

Fn great video! Love the special voice slow down, thanks for making videos all of us can understand...
a gun maker sharing how to make homemade guns, I love this man.
One reason the blank slipped in the 5C collet in the CNC is that the stock as unfinished surface on it, which may or may not be round and on size. 5C collets cam't hold anything that is on the positive side of the nominal size and only a few thou under. ER collets would fare better here, as they can collapse almost always to the next size down.
Yes, very informative and loved the really "hands on" approach here. Lessens the amount of "but I don't have a file/drill/CNC/factory" crowd
Just found this channel, this being the first video I've watched... Got here in the course of wondering if a .22 could be rebored to .27 and what could be done about the rifling. Hypothetically of course, such a thing would have no use in britain.
The twist rate depends on the weight of the arrow in Minecraft of course

" remember, never ream with a hand drill" *meanwhile continues to ream with a hand drill* lol great video 👍
Mark, so your hand tooled barrel came out a bit oversized 🤔, no problem, just use a slightly larger diameter projectile to make up the difference, or use a projectile with a sabot 👍, see no problems 🤗.
You know, people get all worked up over slight issues in the bores of barrels. Most people don't know that a crappy-looking bore can shoot better than a pretty one. At the end of the day, firing a bullet amounts to swedging a metal projectile down a grooved bore using a near explosion of burning plasma at supersonic speeds. Do you really think the bullet "cares" about its passageway being .001" oversized?
@@markserbu In precision .22 pistols, the ammo manufacturers make different diameter bullets of equal quality. It makes a big difference in accuracy; my pistol works better with the larger diameter. Some target rifles are designed for best accuracy with the smaller bullets, i.e. gun designed with a smaller bore to match the standard diameter bullets. Yes the bullet "cares" a lot whether the bore diameter matches the bullet diameter. Although for function, no it doesn't matter.
