Neck turning strategy - just want to double check

[INTJ]

dropping the turner in a bucket of ice-water between cases will go a long ways to help with uniform neck thickness.

Or setting it in a block of ice. It's amazing how much more consistent necks are after turning when you keep the turner the same temp, a little on the cool side.

Now if you leave the turner on the when you take a break, it will cold soak and should be warmed up before you use it again.

Great thread Mike! A lot of great info to be gleaned for us novice neck turners

Hows that GT40 running?

She's looking good! Spun on a stainless 27" barrel and running it suppressed now.

Yesterday I turned 100ea 2x fired Dasher cases, I basically have the same setup without tho motor, picked three random cases and measured them Starrett ball mic

Quest450,
Is that a dewalt electric screwdriver or a impact driver?

Wane, it’s the gyroscopic screwdriver

oh cool I was hoping it wasn’t a impact. I couldn’t find a Dewalt when I wanted one so I bought a Ryobi thinking I would replace it but liked it well enough I bought another one when the old ones battery wore out. Perfect speed for the job huh?

It's a little slow I guess 0-480 RPM but it does a nice smooth cut
I only clean up my necks .001

You don't need to mount your lathe? Just let it sit on the rag?

you can, I don't and use it as shown in the picture, it's stable enough and doesn't really move

Are you holding a 0.0001" through out?

I just checked a larger sample, 10 cases, measured each neck in three different spots

1. 0.01195 - 0.01205
2. 0.01995 - 0.01200
3. 0.01200 - 0.01205
4. 0.01190 - 0.01200
5. 0.01190 - 0.01200
6. 0.01195 - 0.01200
7. 0.01195 - 0.01200
8. 0.01195 x3
9. 0.01195 - 0.01200
10 0.01195 - 0.01200

I think I have waaaaay too much time om my hands

That’s good turning!.... I may be able to turn that well but I doubt I can measure that well.

in the future
if .012 is the goal,
do a rough 1st turn at .0127 or so,
then a final at .0120
that small final cut tends to be easier to maintain a smooth final and keep temp down

Ice bucket for the cutter sounds logical to keep it cool, but won't some parts of it rust?
I have a new PMA with carbide cutter. But I'm thinking screws, springs, might be regular steel and will rust.
Could take it completely apart to dry, but then the setting is lost.
How does everyone keep it dry/prevent rust when cooling it in ice water?

I gave up on a powered options and went back to a Forester hand crank for a better feel.
I prep the new brass as a would for reloading - sizing - expanding - trimming - chamfering and then turn the neck. Then I hand rub the neck and rim with XXXXXX steel wool and tumble to clean off oil and such.
