[QUOTE="25WSM, post: 1782751, member: 38048"] Well I can say that a receiver sticking out of my headstock with the trigger and bases still on spin up pretty smooth. You physically can not feel any vibration in the machine. You got a 3000 pound base it's all riding on. Threading is only a low rpm operation if you choose to run low back gear. Lots of guys run 60 to 70 rpm because they are cutting manually and things happen fast. 60 rpm gives you time to think and react. I manually thread myself but I run the highest back gear I have. It's in the 300 range. The extra speed gets the job done faster and the threads are much nicer and smoother. Even the speed I run is slow and requires me to run high speed steel bits to get that smooth finish. Carbide bits need lots of speed. After 30 yrs of cutting on a manual lathe you get good at it. I did work as a machinist before I set up my own shop and really hated it. But I came into my own when I started building the custom rifles. Shep [/QUOTE]
