Title: Thread Die Set - very unusual
Post by: JoeCB on August 20, 2016, 09:45:16 AM

Hello all, not mine but a friends... This very unusual and nicely made Thread Die set has 4 sets of interchangeable dies giving a total of 14 thread sizes from 1/4 to 3/4 , both fine and standard thread forms, plus 1/8 NPT. Marked .. Zoerman Company, Jackson Mich USA,  Pat'd Aug 1922. Very nicely made, handles flip out and lock for use then fold for storage. Ever seen one like it?

Crazy. That thing must have been expensive as heck to produce. I love it!

Wow, new to me, awesome find and other than the box it looks to be in good condition with all of the original pieces.
