Grazie Antonio! Mi fa molto piacere il tuo commento!!

Thanks a lot, happy that you like My channel and my videos, new video Is under making and It will come out soon! Alberto 🤓🇮🇹

Not all Italians, only the italians like me that did not speak a good English 😂🇮🇹

@@ab-shop you speak very good English. I understand everything 🙌🏽

@@AlabamaTree Thanks a bunch, you are super kind 😀

Ciao non possiedo più quel tornio, come vedi da qualche anno ho un Colchester Bantam! Il diametro era da 125 mm! Gli avevo fatto un attacco rapido con dei perni, a sgancio rapido!

@@ab-shop grazie

@@Maker-in-Garage Figurati 😀

Good morning, yes just a bit, i don't Remember the difference in weight! There Is also a bigger version then mine! But at 1000 euros more, so around 4000 euros.

Su AliExpress scrivi " joystick 4 axis" e te lo propone subito, su Amazon scrivi" interruttore joystick 2 posizioni", ci ne sono di vari tipi.

@@ab-shop grazie

@@devilvortex1 Di nulla!!😀

Ciao Paul! Thanks a lot, i decided that It was arrived the moment to put a motor! See you soon Paul, Alberto 🇮🇹

Thanks Adrian you are welcome!🇮🇹

Ciao Silvano, felice di rivederti! Si guarda era un progetto nel cassetto da tempo, era diventato faticoso! Non ho contrappesi è fluida, piuttosto mi farebbe piacere se fosse più rigida, ma per quello mi sa che si può fare poco! Tu hai fatto qualcosa in tal senso?

Come avrai avuto modo di vedere, io ho motorizzato la Z da sopra e direttamente sulla vite testa e quindi mi è stato necessario mettere un contrappeso di circa 50kg circa corrispondente al peso della testa ( stesso principio dell'ascensore ) di conseguenza stessa energia impiegata in discesa e in risalita - ovviamente non porta benefici in termini di rigidità ma l'aumento dei peso complessivo contribuisce a smorzare le vibrazioni da lavoro Avevo pensato anche a renderla più rigida ma col tempo ho imparato ad usarla al meglio - per quello che è Ciao

Thanks Matt, It Is what i thought when i start the project, where something was difficult to make, i promised to myself to use the 3D printer as much as possible!

Difficult to make a stepper motor at home..

Thanks Brian, super happy that you like the video!

Ciao Andrew, always super thanks for your comment: for the first time it's a video in which mechanics, electronics and reverse-engineering (3D printing) coexist, I tried to take advantage of everything I have available in my workshop to get to the bottom of it ; I chose the stepper motor only for the torque, which is really high, I know that it is a bit wasted to turn back and forth compared to the possibilities it offers in position control, but a 24 Volt DC motor would have been much more cumbersome! As I have written in the description, I went crazy trying to figure out how to reverse the motion...here's the part that made me waste the most time! 🤭

@@ab-shop So well worth all that effort. Bravo 👏

Too kind Joseph, happy that you liked my project 😀

Grazie a te Bruno, sono impazzito con la lunghezza della cinghia, credo che ci sia qualcosa di strano nelle cinghie importate dalla Cina, 2 mm in più nella lunghezza sono poi invece 4-5 mm, ne ho provate(e acquistate) 4, non volevo usare un tendi cinghia! Riguardo invece alla dimensione, volevo provare la HD3, poi ho visto che forza fanno le GT2 della mia stampante 3D e ho pensato fosse abbastanza ed infatti è stato cosi 😀 Bello sarebbe averti come maestro Bruno 😀

@@ab-shop maestro è una parola grossa, sono solo un appassionato autodidatta di aeromodellismo e meccanica (professionalmente sono e vengo dalla sanità), in atto sto approfondendo il mondo dei controlli e di arduino per le macchine utensili, e quindi comincio a conoscere le potenzialità. Ps: se dobbiamo parlare di meccanica il maestro sei senza dubbio tu. Ciao

@@brunoartuso6612 Troppo gentile! Una decina di anni fa avevo iniziato anch'io con aeromodelli ma poi pilotare mi metteva troppo stress, mi piaceva di più costruire ecco perché son qui 🤭

I know what you mean, It Is not a problem of money but a problem of space, with more space i should buy a bigger milling machine of course!😅

But.... the milling machine does not know that! So it works! 😅

@@dreamsteam8272 Yes It is 😀

Thanks 😀

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…

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 !

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!

Of course, if you have a divisor axis ( you can use a stepper motor to do this), It would be easier, but i don't have It and so i used the old machinist mode!

Thanks so much!!

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 😀

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!

Thanks Rusti for your kind message, happy that you like it 😀

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?

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!!

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

Thanks for your wonderful comment Fred!!

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!

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! 😀

Thank you Rusty 😀

Grazie 😀orgoglioso ti sia piaciuto 😀❤️

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!!
