Mira especificaciones Sammi, para 9mm son 8.79mm de diámetro interno, pero puedes usar una broca de 11/32 que son mas accesibles y el diámetro de las estrías es de 9.01mm.
Before I started with the grooves I ground each end down to a size that was a sliding fit in the bore (shown at 0:56). I used those ground ends as a guide to know how deep to make the grooves. Better if they are deeper than needed than not deep enough. The button was made from a 9.5mm (.375") ejector pin. This is oversized. I didn't show it in the video but after making the grooves I ground it to a slightly smaller diameter.
Yes, the slots will make the barrel more accurate. In this video (ruclips.net/video/sx8OgOJusXo/видео.html) you can see me shooting my first barrel. It was more crudely made than this one but it worked. You may have to research or experiment to find the best twist rate for the bullet you are using.
Hello friend, I did the same but with an original rifling button from Aliexpress, and the tube expanded internally, when passing the rifling button, is there any way to reduce its internal diameter?
Срез ствола не равномерен из за нарушенной геометрии нарезного штыря и материал тоже не годится так как его твёрдость не превышает твёрдость заготовки .С такого можно стрелять но пару раз так как пуля в канале ствола разрушиться или застрянет из за сбитого шага нареза. Итог - материал не подходящий метод выдаёт низкое качество выходящего продукта
Esa algo artesanal, casero idiota, no esperes el control de calidad, de Beretta, mcmillan, acuracy international. Etc. Es casero, comprendes? El acero supongo debe ser como 4041, la 9mm solo genra 250 Mpa, mietras ese metal resiste asta 250000 mpa(dependiendo su grosor) lo de las estrias obviamente se desgastan. Hasta las marcas reconocidas tienen una vida util de disparos, 10000 disparos en Glock por ejemplo. Este es un trabajo barato, oara un trabajo barato, en países pobres, funcinal para la misión, no una arma para heredar a tus generaciones. Por que si piensas de esa manera, pidiendo calidad, y barato. Estas muy equivocado.

Se supone que el cañon rayado de un arma debe ser de maxima precisión, no veo como puede hacerse eso con un rayador echo a pulso con una pequeñs esmeriladora. 😢😖😡👹

Great work, love the ingenuity! Question though?
By having the rifling on the bit and with you pushing it in, is that just spiraling on its own?
Yes it is.
The button presses the lands and grooves into the barrel wall instead of removing metal. 😮😮😮
Que brocas utilizaste para hacer el cañon, de que medidas ? Osea de cuentos milímetros? 😊

Exelente ¡ de Argentina . Cuantos grados la fresa...

What steel was the rifling button made from?
It was cut from a injection molding machine ejector pin. The rods I used to push it through are also ejector pins of a smaller diameter.
Hi! Could I ask what is the diameter of the rifling button that you made ? How deep is the groove? Thanks

@@ottowhack9248 Thanks for the info!
Excellent video friend, do you have accuracy when shooting with these slots?
I want to make one for an air rifle

Not that I can think of. Might need to try again with a thicker stronger barrel.
@@ottowhack9248 gracias amigo
What does the id have to be right before 9mm button...
8.8mm
thank you...great video!
What size bolt did you start out with?
3/4x10 thread
Con estas estrias si tiene precisión el cañon amigo?
what about rfile bottom..like 556 or 762
Beautifull❤
Amazing
Nice
are you aware that you can order rifling buttons from a large asian country?
if you mean alixpress you can no longer get it.
Okay perfect

It is very wrong to use this type of barrel because it must be 4041 steel, which is less ductile
Shut up nerd
Sure, fine. glad you can afford to buy not only the lathe but all the fancy smancy snob ass "do it THIS WAY" materials.

4141 eger dövülmemişse oda hiç bir işe yaramaz her hangi bir çeligi döv en iyi çelik odur..
I think you are referring to 4140, not 4041?

ESE CAÑON EMPIRICO, SERA PARA QUE LA BALA SE ATASQUE Y ME REVIENTE EN LA CARA
Nada mal para algo casero
Concordo, porem penso que a precisao disso nao seria top, nao sei se voce viu mas parece que o "furo" nao esta no centro do "cano"
Ich mag die Idee dahinter, aber das Ergebnis der Züge und Felder ist wirklich grauenhaft!
More American gun mania.
This tube is too rough and useless.
