Who needs a lathe?

Only 499 to go

Hi Tim
i have been using a K&M neck turner and never got a spring of brass like that
I now own a lathe an thinking of doing it on a home made mandrel

This will help with no heat buildup due to friction on the pilot
i usually do 5 at at time on the K&M then wait 10-15 minutes and another 5.

Using my .0001 ball mic that gave me great results but did take lots of time to do 300 308 cases

Let us know how you go doing the other 499

I have a K & M which I've recently fitted with the 50 cal heat sink handle.

That aside, I've been able to turn continuous cuts using a practice an American correspondent uses. I put the cutter in water between cuts while I'm mounting a new case on the holder. I've found that a .30 cal Berger bullet box is about perfect size to catch the adjustment knob on the box edge while dunking the mandrel & cutter in water, the level of which I adjust to suit. I lube the mandrel once per run with Imperial sizing wax (OK I don't use all that much so haven't bought the newer label yet) & the water does the job from there on. Apart from it being a lube, it keeps the mandrel from expanding with heat & washes off those nuisance chips most of the time.

I dry it off with toweling after & give it a good squirt of my favourite dewatering fluid (that is whatever one is closest to the bench).

Dipping in water

Never thought of that
Wonder if a water soluble coolant/lubricant would help this process too

Great points and may give that a try next time

I use the K&M with a big handle too, with a drop of cutting oil each time and a tooth brush for a quick clean when I don't get a perfect spring.

Might be worth a look at the 21st century set up with a floating head to allow for variations, check you tube for some lathe systems

I am taking a quick break from a neck turning session as well.
Yes, the handle in a small container of water. I just use plain water to rest it in, just a quick flick when you pick it up and it is dry enough, no messy coolant or anything to deal with.
The carbide mandrels are better than the steel ones, less friction and heat build up.
I just wish the expander mandrels were half a thou bigger.
