I tried the tubing cutter also and it does a much nicer job than a hack saw. I've also tried chucking them up in the lathe to cut them but my parting tool is a bit wide for something like this.Need a narrower one. Mine is carbide and my grinder won't hardly touch it.
Anyway,it was kinda hard for me to hold the casing and crank the cutter around,my grip isn't what it used to be. Brass is quite a bit harder than copper tubing to cut,even though I was taking light cuts with it.
