By the way, @Deleted User , what are you going to produce with that drilling/milling beast?

I do a lot of work on firearms, the bed on this lathe is 31 in between centers so I can turn barrels

You know, I was __*EXACTLY*__ thinking that you could do that...

👍

Barrel blanks are relatively cheap

If you haven't been there check out Green Mountain barrels

Sometimes they have clearances

Or overruns

Might be interesting to have a stockpile of barrels, in case the lights go out.

Deep Drilling and rifling is beyond my ability at the moment

I was going to ask about how rifling would be done.

Also, what rust inhibitor would be applied?

Prob have to send out for that process.

Some of the barrels for sale on GMB mention chrome lined, some don’t.

Hmm...

Do you know what a sine bar is?

No clue what a sine bar is, but I will in a minute.

I think it may be possible to build a sine bar rifling attachment for my lathe

As opposed to a complete machine

I skimmed through a “sine bar” video, and the guy was describing trig functions.

I haven’t used that in a few decades.

But I still remember it!

Now I’m deciding how to apply that to barrels.

Check this out:

In that video the angled green bar above the machine is the sine bar

The long blue bar underneath it engages with the sign bar causing it to move back and forth that in turn turns the Chuck holding the cutter

By adjusting the sine bar you can adjust the twist rate of the barrel

That’s pretty cool.

Holy Schnikees, @Deleted User , you cleaned the place up already. Lmao

I’m listening to the video you posted, entitled, “WOE TO YOU TAMUDIC ZIONISTS FOR YOUR TIME IS SHORT derek broes”

Pretty wild.

The guy’s heart seems in the right place.

It’s Russian hackers for sure.

And by Russian, I mean Chinese.

@Karnivore Hows it going?
