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. :)

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.

I started rifling my own barrel when I was 14... and you are right.... it is a rewarding experience.

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.

It makes me happy to see I'm not the only one that has a problem drilling straight holes :)...

the Idahoan, makes rifled pistol barrels with a press and home made bit. He didn't fire and quench it, but it worked fine

If I didn’t know who Mark Serbu is, this video wouldn’t be nearly as fascinating.

Wow KZfaq algorithm, information I didn’t know I needed.

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.

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.

Great that you showed the failings and problems that you ran into along the way. Thanks for this.

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.

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!

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

I was already giving up on making my own black powder gun, but watching your video I think I can. Thanks.

"These calipers are messed up..." Literally my experience with every set of calipers.

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.

I've decided that this will be my school science project next week

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.

I am from Scotland in the UK. We have a saying here. "Rough as a bear's arse". I would guess that you'll understand, but as long as it keeps the bad chaps away, please continue.

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

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.

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

Just awesome someone has taken the time to show home builders how to do so.

This guy is awesome. This is called thinking outside the box and it's very inspirational for educational purposes. Thanks

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

"How to rifle your own barrel": "Don't do this" "This is stupid" "This is wrong". Best video ever, thank you!

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...

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

Mark Serbu my favorite guy in the firearms industry to watch

Now you gotta do home shop headspacing. Ha goodluck! ;)

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.

Thanks for setting up Edwin. That guy is hilarious.

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

😂 This is the funniest thing I ever watched.😅

Mark you're the most self deprecating craftsman ever hahaha... you remind me of a more advanced version of myself.

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.

Ream it after you drill it, while it’s still on the drill press locked in the vice. Cutting oil really helps 😊

I just found this video and man, I hope your Safety Squints were in "angle grinder" mode for this project! Loved it.

You build some awesome guns but everything about this video is sketchy as shit. Which means I can for sure do it at home!

Primitive Pete. So simple, even a Cave Man can do it.

This must be the best how not to and why video I have seen on YT :))

Very encouraging! Thanks Serbu. You are a gentleman and a scholar. Thanks for breaking it down! Bringing the power to the people

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

love what you're doing with these vids Mark!

How to get put on a watchlist 101 I love this

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 !

Hahaha "you got a dart in your neck" what!?" Your crazy man, I like you"

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!

At least you’re not wearing a ring brother. But if I had to guess the Zip disk would shatter on contact with paw lmao. Thank you for the video.

only man brave enough I've seen to hold your hand that close to a cutting wheel

next video : how to make Apollo 666 from the shoe box and 3 yards of duck tape

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

Jaysis! I don't know how many mini heart attacks I had watching this!

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.

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

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?

Thanks Mark love the simple way you rifled that barrel!

4:45 "its perfectly fine to do it dry" famous last words ;)

This should be called “everything you should never do”

that subtle jab at royalnonesuch was spot on :p

If improv was a person it’s definitely mark serbu lol

Who let the boss in the shop unsupervised. lmao 😂

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.

This was a osha night mare lol loved it. Safety Sally's somewhere were screaming.

I dont know why ,but I have laugh all the time.😂.Nice work!👍

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

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.

As a school-trained Master Gunsmith, this video gave me flashbacks of training apprentices. Thanks.

I like how you put pictures of tools in the video.

Makes me appreciate the old old school blacksmith out there in the dirt knocking it out

Watching you wrangle that death wheel had me puckering.

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

This is like watching a bloke milk a slug

Thanks for doing it with simple tools. And, thank you for showing us the right way!

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.

"....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 have watched probably tens of thousands of KZfaq 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

Dude your my hero I can’t find 22barrel liner no where your video is a great help

Fn great video! Love the special voice slow down, thanks for making videos all of us can understand...

What u came here for is at 24:40, real action.

I had to go back in time to find this gem of content 😮

a gun maker sharing how to make homemade guns, I love this man.

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

" remember, never ream with a hand drill" *meanwhile continues to ream with a hand drill* lol great video 👍

I love that your dial caliper is in the same working condition as mine. At least it works as a divider if you hold it JUST right.

They should teach this in schools.

Omg I just wanted to jump through the phone and help you. You got a shop full of nice tools and don't know how to use any of them.

This video shows quite clearly, what NOT to do. I was chuckling the whole time. Made me think of the most frightening words a pilot can say. "Watch this".

No one, no where, EVER do anything he just did! I think hes an awesome guy, & I appreciate the work that has his name on it but not sure he should make you tube videos.

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. BE A GOD OF ,MATERIAL GOODS!!! ")

I could feel the gates of Hell open at the scream on 9:04

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.

This man flexing by throwing precision out the window.

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.

chuck that in a lathe and have a tapered barrel! will look great! follow your bore!

Great teaching materials for people in countries where gun making and owning is forbidden by law, but needed something to defend themselves from the cruel government law. 🤔🤔🤔 Love this DIY instruction.

Same as the rest of your videos , amazing.

nice for handgun barrel.....I'd like to see a 20" rifle..... :)
