What tool is used to cut rifling? And what do I need to use one?

a lathe i imagine

A big ass lathe

You'll need a broach

Well broach isn't right. A reamer for your maximum thread ID and then something to cut the threads

5r better if you want to put the work into it

I doubt it's a lathe

Not a normal one

define normal

you know what

get a drill press and try it

It will run on a normal lathe

Its gonna blow chunks and your gonna be hanging off the end but it will run

Even then that still doesn't answer the question of what kind of cutter it is

I recrowned a mosin can I post in here?

I forget the tool name

GTS nigga

Rifling is traditionally cut by a special gun drilling machine. Its a single purpose machine that pushes a very hard button through the barrel repeatedly. Sometimes 1 machine is several spindles together. They are liquid cooled.

Here is the cutting edge and base. You can see the holes for the coolant.

You just push the carbide through and the lubricant keeps it from setting itself on fire & floats the chips out

Home rifling to commercial quality is not possible. You can produce "rifling" with some screw jigs. Remember it's two steps. 1. Drill barrel from bar stock 2. Cut grooves with high pressure carbide button

I never got into rifling

Just buy a kreiger, proof, or bartlen

Get it hand lapped

You can cut some not terrible rifling if you have a smooth barrel blank that is reamed correctly already & a hydraulic press

You will need a button like this

You got the print for a 5r button?

Just get a catalog from whatever tool supplier is willing to sell to you

I'm pretty sure 5r can be cut with a button rather than an expensive broach. As long as the twist rate is the same inside

Weird looking rifling I tell you hwat. First i've seen it

5r?

It's so much better than standard imo

It applies better pressure on the bullet and equalizes the spin

I worked making coonans for half a year, anyone familiar with them?

Was rimlock ever a big issue?

Depends on the gun

Enfields, with proper ammo? Almost never

Mannlicher rifles had the en-blocks to stop it from happening, and nuggets
