You can do that on a mini-lathe, too.

What sort of wall thickness were you able to achieve?
And was that for a particular purpose or were you just experimenting?

I’m thinking the coolant was not used for the video?
Seemed like a lot of heat building up.

I don't remember the wall thickness, I was making a punch for some soft material. So, the ID was the only thing I cared about.

I had to do some experimenting after Jon posted those previous videos of the copper forming. This is just 3/4" copper tube down to about 1/2"

I just ground a piece of HS Steel cutting tool to a rounded profile. I was not able to polish the surface as much as necessary to get a really nice finish. You notice the surface is a bit rough, I feel like if I spent the time polishing the tool surface, the result would be much better.
