    Lathe threading insert for getting close to a shoulder.

    Does anyone have a recommendation for a threading insert that will get right up to a shoulder? I'm currently grinding back a 16ER laydown style insert, but that's a pain, so I'm looking for something I can use out of the box.

    Brother power issues?

    What wire size are you guys using to power your Brothers? We recently got a TC-R2B. It's running fine except that we get an alarm when starting the spindle from a dead stop to a higher RPM. If I command M3 S8000, it's fine. If I command M3 S9000, it alarms out right away. This happens every...

It's a 5/16-18 thread. If you look at the crests of the thread, you can see how they alternate between a skinny...

    I have a Wasino SH-5. It's a lathe with live tools where one of the turret positions has a small sub-spindle chuck. The live tools and sub-spindle are all driven by the same motor. When rotating the live tools, the sub spins at the same time. It's a weird configuration, I know. I am picking off...
