Restoring a Geometric Threading Die Head

I take apart a 5/16 DSA Geometric Die Head, clean and check everything, then put it all back together. I did the same thing a few weeks prior but with a 9/16 DSA Geometric Die Head but didn't make a video of it so I thought I would do it this time instead.

These were made by the Greenfield Tap and Die Company a long time ago.

There are many different Die Heads made by many different companies. A similar model was called Rubometric

It's a very nice tool and I very much enjoy bringing old tools back to life. ... https://www.youtube.com/watch?v=2wxdZBMlXb4
