 If you want UFO's turned take them to a real machine shop. One that does
industrial equipment not automotive. These are the kinds of shops that dont
have to develop anything, they already have the required tooling on the
shelf. More benefits, they dont use brake lathes, they use big industrial
lathes built 30 years ago that weigh in at around 5 tons and guys that can
set a lathe up to shave a hair off a flea's ass without leaving stubble.

 I had mine turned this way. The lathe used had a head that measured in at
around 36" and the guy running it looked like he started working in a
blacksmiths shop around the turn of the century. My before and after runout
check was easy, before: brutal vibration, after: smooth sailing for 30 months
and 4 sets of pads. Cost: $110 for the pair.
