Homemade Rifling Machine | New Idea Solve An Old Problem

[@ftownroe]

Another absolutely fantastic project.

[@ab-shop]

Thanks for your wonderful comment Fred!!

[@TheRecreationalMachinist]

Cheers Alberto. Good to see you busy in the workshop again 👍 🇬🇧

[@ab-shop]

Hi Matt! Yes! :) i need 1 month 1/2 to arrive to the end, to win a bet with a friend that now have to pay me 2 beers!🤭 No great pitch on lathe? Yes, It Is possible 😀

[@MyLilMule]

Nicely engineered, Alberto. Well done.

[@ab-shop]

Ciao Greg! Very happy to hear from you!! Happy you think that about the video, first "how to make a long pitch", second " how to make a cutter that cut"! Ciao Greg have a nice week!! Alberto

[@termlimit]

Awesome project! Any chance you have plans? Really interested in how you made the cam for the cutter to use a screw for precise depth of cut adjustments. Thank you!

[@ab-shop]

Thanks for your comment! I upload the drawings on "Homemadetools.com", there you can find it!!

[@termlimit]

@@ab-shop brilliant, found it. Thank you!

[@ab-shop]

@@termlimit You are welcome !

[@Rustinox]

That's a nice project. With a lot of thinking involved.

[@ab-shop]

Thanks Rusti, not easy to make a cutter that have to cut 😀

[@Preso58]

Wow, made my brain hurt just looking at the build. Nice job, Alberto.

[@ab-shop]

Wow Is My answer to your comment, Mark 🤭 Thanks Mark! It was a long time that i tried to solve that " problem", a small pitch in the same axis of a long pitch! 😀

[@GardenTractorBoy]

This looked like a fun project and it turned out great, thanks

[@ab-shop]

Thanks Joseph, the most big challenge until now...here in my channel !! :)

[@andrewdolinskiatcarpathian]

Wow! Alberto. Now I know why you have been so quiet recently. What a project. So involved. So many processes. Enthralling from beginning to end. Thank you for sharing. 👏👏👍😀

[@ab-shop]

Ciao dear Andrew, thank you for stopping by! Yes first the "how to make a long pitch", after " how to make a cutter that cut 🤭", so It Is a tool and a machine in the same time 😀 Happy to hear from you dear Andrew, see you soon with a new project! Alberto 🇮🇹

[@benedettacastagna8856]

Complimenti Alberto, un bel progetto 💪🏻

[@ab-shop]

Grazie 😀orgoglioso ti sia piaciuto 😀❤️

[@billdoodson4232]

So; I'm going to be really interested to see what this has been built for. That looks like it will be the real project.

[@ab-shop]

Hi bill and thanks for the message, it is a machine capable of performing a "helix" cut with a pitch that is not found on a lathe, because threads with a pitch of 250 mm or more do not exist; it was a bet with myself to be able to build a compact machine that could do that type of work, therefore to rifling a gun barrel or to create slots for lubrication (spidering)

[@billdoodson4232]

@ab-shop There is no better reason than, "I wonder if I can. Yes I can"

[@ab-shop]

@@billdoodson4232 Yes really!!

[@williammorris1763]

Looks good. very similar to the old machines they originally made to semi automate this process. more advanced than the musket bore OG wood one too.

[@ab-shop]

Thanks William, you know i dream to make this device for 1 year, i decide to make it after the idler joint idea: before that the project was stuck! Another problem to solve was the cutter, in HSS not problem but in normal carbon steel not easy to make sharp edge, that It gas to cut like a knife!

[@daveb3910]

Really like your choice of music

[@ab-shop]

Happy, Dave, that you like it !! :)

[@williammorris1763]

Same ❤ 🔥

[@torchmd]

That’s funny. I can{t stand the music. To each their own.

[@Eatherbreather]

I can't find the music - especially the first track. Can anyone tell me what it is?

[@MrCheezeus]

you really should remove your wedding band while machining ... it's real easy to receive a degloving injury working with heavy machinery

[@allangibson8494]

Any jewellery is a potential issue (along with long hair, beards and loose clothing). Very easy to have a life changing injury with machine tools.

[@canadianoddy8504]

Very nice work. Clearly you are very skilled. I made a Clint Westwood design rifling machine out of scrap metal I had laying around. It did work ---- sort of. The real problem is doing small bore rifling like .22 cal. Your machine would only be good for large caliber like 9mm as is the Clint Westwood design. Just my opinions. CO

[@olegplisiuk4687]

Это не совсем так. Сама конструкция прекрасно сработает с любым калибром. Но сам резец, для 22lr, имеет другой вид. Он цельный, и роль и оси и пружины выполняет разрез в материале резца. Представте себе цангу фрезерного станка, на одной из губок которой торчит зуб резца, а вместо фрезы - в коническое отверстие в середине - вкручивается винт, раздвигающий губки. Вот так и выглядит резец для 22. Только две губки всего

[@canadianoddy8504]

@@olegplisiuk4687 Спасибо, что прояснили это. Я обнаружил, что любой стержень, на котором есть резец для калибра .22, стержень очень маленький и будет гнуться, если только он не очень короткий, как у короткого ствола пистолета. О стволах под калибр .22 не может быть и речи.

[@olegplisiuk4687]

@@canadianoddy8504 нет- нет! При нарезке 22 калибра - резец не толкается! Он тянется, и натянутый стержень становится ровным как струна. Проблема в том, что он способен скручиваться, и не передавать резцу угол копира. Поэтому сам резец обязан быть с углом, соответствующим углу копира ( твисту), и тогда он правильно идет в металле

[@canadianoddy8504]

@@olegplisiuk4687 Теперь это имеет смысл.

[@ab-shop]

Thanks to everyone for the comments, for sure you can get to 8 mm, the first version of my video was with an 8 (mm) head (in fact the central shaft has a thin diameter of 7.5 mm to be able to switch to minimum in an 8 mm hole) but then I encountered friction problems; it certainly cannot be used, given how it is built, for a .22 LR, in which case you need a "button tool", but also a hydraulic press, due to the high efforts it requires!!

[@everythingtv1910]

I like this video it is amazing thank you for sharing to view and i wish your channel more success

[@geppettocollodi8945]

Is that for a pistol with a 1.5 inch long barrel?

[@ab-shop]

@@geppettocollodi8945 Ciao Geppetto non è per nessuna pistola, solo una sfida che ho voluto vincere da tempo con me stesso, si possono fare rigature di qualsiasi passo e su diametri da 14 mm in su, sotto è difficile per la costruzione del porta utensile che diventa laboriosa e micrometrica..si possono fare anche ragnature per lubrificante come quelle che si vedono sulle bussole delle macchine utensili. Ciao, Alberto

[@RustyInventions-wz6ir]

Very interesting. Good work

[@ab-shop]

Thank you Rusty 😀

[@floutv4004]

Was hast du da genau genau gebaut und was kann man damit manchen?

[@ab-shop]

Guten Morgen, ich habe eine Maschine gebaut, die in der Lage ist, einen Propeller mit einer sehr großen Steigung zu beschreiben. Mit dieser Maschine können Sie beispielsweise das Gewehr der Läufe oder die Ölkanäle zur Schmierung erstellen! Damit habe ich eine Wette gewonnen, nämlich dass es auch auf einer Standard-Drehmaschine möglich ist, Bearbeitungen mit enormen Teilungen wie 1:250 mm durchzuführen.

[@simonesalamon4388]

Grande! Conosci la miss passione quindi non posso che dirti ❤

Grazie mille 😀❤️

[@fainderskurs-koi8767]

Лайк. Хорошее видео.👍

[@MutumDevarishi]

What's this method called?

[@ab-shop]

Hi Mutum, the method Is barrel rifling, It Is an old method with a new idea, putting in the same axis a small pitch and a long pitch ( i have described on the video information), you can make the longer pitch you want!

[@fattmouth7715]

Fantastic video but you almost lost me with that TIG welding

[@samrodian919]

Yes it was of pigeon shit MIG quality lol

[@wellingtonrodrigues6659]

very good idea

ciao Alberto vedo un progetto esteso -si parte da un idea fissa poi si disegna e via di tornio e fresa ..salda affila e montaggio - si un opera così definita è molto impegnativa ....però quel colore della camma ..mai visto....torce un pò la vistaa

[@ab-shop]

Grazie Renzo ho scelto arancione perché attrae la vista!! Un super grazie per il tuo commento e non solo!!😀

[@adriandumitrascu4292]

homemade ECM is the way, no need a lathe for that :D

[@allangibson8494]

You obviously haven’t tried to make an ECM machine without a lathe…

[@hulksmash6476]

Why not use a rifling button?

[@ab-shop]

@@hulksmash6476 Yes correct, because i don't have a press! So i tried another way to arrive at the same result, using a mix of ideas, 3D print parts and lathe parts.

[@hulksmash6476]

@ab-shop clock you bar (dti) in chuck and push through using tailstock with ejector pins of increasing lengths. It would be really cool to see you build a jig and maybe even put hydraulic cylinder, bolt to floor? I am no professional gunsmith dude, I did mechanical engineering but in injection moulding industry. Keep on keeping on 😉

[@ab-shop]

@@hulksmash6476 Thanks for your comment, i will think about It, every new idea can be a new challenge and a new video!! A big ciao from Italy, Alberto 🇮🇹

This video is worth a subscribe!

Thanks so much!!

[@agentcovert]

The VFD on the lathe looks scary.. unfortunately VFDs have a nasty problem with frosting then fluting the bearings on a machine..as stray power builds up on the electric motor shaft being powered to about 70v then finds ground / earth thru the bearings a few dozen times per second of use..at 600 - 700hrs serious damage has happened and the bearings need replacement.. but simply adding a ground/ earth strap to the motor shaft giving a path not thru the bearings prevents this entirely.. the better option is to have a rotary phase converter that powers each machine.. usually a single rotary phase converter is used for the entire shop being a one man set up..Cheers..

[@ab-shop]

@@agentcovert Thanks for your comment, i put 4 points of the lathe ( One Is the Dahlander motor) to the earth, from 2017 when i installed the VFD, no problems.( 7 years until now)

[@geoloussian5856]

What called this digital piece on your tailstock to have accurate measurement , i want to buy similiar

[@ab-shop]

Hi and thanks for your comment: It a normal digital caliper that i modified to be installed on my tailstock: on my channel, if you search, you can find the video where i show how to make It, the only difficult thing it's the drilling operation, because It Is hardened steel!

[@thaiprivateeyes]

Dont really know how can justofy home made if using commercial machinery Home made to me means made at home with house hold objects

[@ab-shop]

Difficult to make a stepper motor at home..

[@kreativitasku5048]

I cant make rifling barrel tools only 5$ Just use pipe and rod,

[@williamdevitt7866]

nice but say make one for a 30 caliber bore and say try it on a 24 inch long barrel that will be when i an impressed just saying what you have shown is just basic machining 101

[@ab-shop]

Thanks, if you consider a cam built with a 3D printer you can easily reach 300 mm, therefore a 300 mm barrel; if you always have the cam made in plastic (because it makes no sense in steel if you don't make 100 barrels a day in series...) but with a CNC milling machine, you can easily reach 24 inches and even more, obviously it must have a larger lathe then mine: the limit is represented by the length of the lathe, with my lathe I reach a maximum of 150 mm; so, if you think about it, it's not really basic machining…
