Hello Gentlemen!
I've got a project coming up soon that is going to require a few hundred internal threads done that are fairly long. I'm not the biggest fan of rushing to disengage the halfnut milliseconds before it goes crashing into a shoulder at high speeds. And this is even worse with internal threads as and lathe owner knows. So here is my solution! A simple automated carriage stop.

If there is any interest I can post a full write up on the "build". It's essentially just a simply trigger, Luckily I know my guns!

Anywho...Enjoy!
