The acme threading is turning out flawless👌🏻 This is how a lathe is suppose to thread. Perfectly aligned each and every pass. No follower rest needed for this shaft. The sides of the threads look just a nice as the grind on the carbide insert, almost like it’s a ground thread. Needless to say, I’m happy with how our new @pmmachines412 lathe is performing. 3/4-5 left hand acme thread. #abom79 #singlepointthreading #acmethread #leadscrew #precisionmatthewslathe #manualmachining #manualmachinist

First time running ACME threads went beautifully! It’s cool to see each cutting surface made its own chip! | B & B Hydraulics, Inc.

Aftermarket small engine Carburetors worth it???
