Thanks to Lloyd-ss and Rocker1 I'm doing my first custom one off build.
Now Lloyd sent me a hulk of a .32 barrel! I'm talking you could beat Superman to death with this thing!
Rocker1? Well he sold me a really nice lathe with some cool stuff to go with it!
1st thing I needed to do was take some metal off the barrel. Some metal don't even come close to what has to go!
That would be like saying I need to remove some stuff to make a BattleShip into a row boat!
I did take a few pics that I'll up load later but I have an old friend coming over to give me some advice on what to do as I'm out of practice with lathes.

Need to take a few parts for the lathe in to town and get some stuff.
Barrel wobbles a bit as is so need to correct for that.
Not that I'm worried about what it looks like. I want it heavy and have no plans to try to quite it down.
I actually want it kind of ugly.

Jeff I'm sure that when you're done with this gun it'll be way cool, can't wait to see the finished product

You can see what the breech end looked like to start.

And what I'm still cutting it down to.

I need to get a consistent diameter so it passes through the lathe for further work.
Down fall of a small lathe I guess. Rocker is lucky he suckered me into this lathe before he shoots me!

Same Lathe I have. I did a .357 barrel just like this. It took so long (couple nights) to get it to .505". Told myself I will never do that again. Good luck and can't wait to see the results.

I did the same thing on the same lathe with a springfield .303 barrel , took about 6 hrs all in one shot.. my only advice is to use a carbide insert tool to not have to fight the heat and tool wear.

Yep. Carbide inserts. Found a butt load at an old shop I demoed so they were free.

Looking good there Jeff, it's nice to see some pics, is that one of those Harbor Freight lathes ?

Yes. Rocker1's old lathe. He did a lot of upgrades on it and suckered me into buying it.

With all the stuff he threw in? I got a heck of a deal and he didn't shoot me!

Wayne52 · « **Reply #9 on:** June 28, 2018, 05:41:58 PM »

I've thought about buying one of those but I never expected to ever turn the OD on a barrel with it, just make smaller stuff with it is all, I'm sure it'd be a lot of fun to tinker with.

Privateer · « **Reply #10 on:** June 28, 2018, 05:46:53 PM »

I've been making small parts with it for awhile now.
This is the first large barrel project I've attempted.
I could have ordered a blank and saved a lot of the work but with the trade to Lloyd?
Good time to play.

I think the spindle bore is 20mm , so once you get below .787 , you should be good to go working the barrel in the spindle which will be far more rigid and allow for more depth of cut

Rob M · « **Reply #12 on:** June 28, 2018, 05:51:37 PM »

I take that back , I think the chuck bore is smaller than that , I don't have this lathe model anymore so im not sure..

5/8

yep was just looking it up

YEMX · « **Reply #15 on:** June 28, 2018, 06:33:45 PM »

This project sounds awesome!!

That's the same kind of lathe I'm putting together!

Privateer · « **Reply #16 on:** June 28, 2018, 10:58:40 PM »

The fun part was planning cuts to fit the lathe.
This much barrel turned down, flip it around then do some more.
Then flip it around again a few more times!

All this just to get it on a somewhat close diameter.
The diameter I have it at so far will pass through the lathe for future work.
That involves cutting the breech area to length and turning it down.
I also want to get it close to the outside diameter of the MRod shroud.

Doing good there Jeff!

I see you put some ball bearings on that steady rest. Great idea that I will have to borrow from you!

Lloyd

That steady rest came with the lathe Rocker1 sold me.
Think I'm gonna need another like it but for smaller diameter work. This one handles 1" - 2". Next step down is the one that handles 0" - 1". Littlemachineshop has them.

Are you cutting the whole thing down, or just where it fits into the receiver?
