- Hi world,
I decided to make a little dream come true, a challenge that started as a bet a few years ago, when a friend told me that with the standard parallel lathe you can't make a step as large as the typical 1:250 ( mm) of the internal rifling of a firearm (1 turn in 250 mm) or in any case it goes beyond the metric/inch values (6 mm for example): I don't want to build a weapon (Obviously), but I do win the bet!
Thus this idea was born, an idler joint before a cam, made with a 3D printer (given the reduced efforts on the cam and the 3D detail was the key to making everything, otherwise you would need a CNC milling machine which I don't have) that can be customized with the pitch you want, in my case the cam has a pitch of 1:250 (mm);
The new idea that made me decide to try my hand at the challenge is that the idler joint "releases", separates the linear advancement but not the axial one, which is made up of a cam that anyone can design and print at home: the cylinder of the joint is welded to the M12 screw that passes into the nut of the lathe spindle, the axis instead of the central shaft rotates idle inside the joint bearings.
As you see, on the same axis there is a pitch of 1.75 mm (M12) and a pitch of 250 (mm) (pitch of the plastic cam 1 turn in 250 (mm), so not 1 complete turn anyway because mine lathe is short, with a larger lathe you can reach larger dimensions but the pitch is the same, 250 mm)
New idea with to solve an old problem!! 😀

Another absolutely fantastic project.
Thanks for your wonderful comment Fred!!
That's a nice project. With a lot of thinking involved.
Thanks Rusti, not easy to make a cutter that have to cut 😀
Nicely engineered, Alberto. Well done.
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
Cheers Alberto. Good to see you busy in the workshop again 👍 🇬🇧
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 😀
you really should remove your wedding band while machining ... it's real easy to receive a degloving injury working with heavy machinery
Wow, made my brain hurt just looking at the build. Nice job, Alberto.
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! 😀
Really like your choice of music
Happy, Dave, that you like it !! :)
Same ❤ 🔥
That’s funny. I can{t stand the music. To each their own.
I can't find the music - especially the first track. Can anyone tell me what it is?
This looked like a fun project and it turned out great, thanks
Thanks Joseph, the most big challenge until now...here in my channel !! :)
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. 👏👏👍😀
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 🇮🇹
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.
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!
I like this video it is amazing thank you for sharing to view and i wish your channel more success
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.
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)
@ab-shop There is no better reason than, "I wonder if I can. Yes I can"
@@billdoodson4232 Yes really!!
Complimenti Alberto, un bel progetto 💪🏻
Grazie 😀orgoglioso ti sia piaciuto 😀❤️
Very interesting. Good work
Thank you Rusty 😀
This video is worth a subscribe!
Thanks so much!!
Лайк. Хорошее видео.👍
nice project.
Thanks 😀
The music is nice...😀😀😀
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.

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
@@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.
@@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
@@olegplisiuk4687 Теперь это имеет смысл.
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!!
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
Grazie Renzo ho scelto arancione perché attrae la vista!! Un super grazie per il tuo commento e non solo!!😀
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!
Thanks for your comment! I upload the drawings on "Homemadetools.com", there you can find it!!
@@ab-shop brilliant, found it. Thank you!
@@termlimit You are welcome !
👍🏻
Grande! Conosci la miss passione quindi non posso che dirti ❤
Grazie mille 😀❤️
Was hast du da genau genau gebaut und was kann man damit manchen?
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.
What's this method called?
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!
What called this digital piece on your tailstock to have accurate measurement , i want to buy similiar
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!
Dont really know how can justofy home made if using commercial machinery
Home made to me means made at home with house hold objects
Difficult to make a stepper motor at home..
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
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…
