Intro

This is a 16x54 (16" swing, 54" length) Monarch Series 50 lathe, with the (maybe) original DC spindle drive.

The machine was built in March 1969 as serial number 49916, and sold to the N.A. Woodworth Company (formerly at 1300 East Nine Mile Road, Detroit, MI 48220) on 1969-03-14 (Pi day!). It is likely one of only a couple hundred ever built.

In 2005, a Spirit Electric / Bardac Drives SLX15/27 replacement DC drive was selected for the machine, but never installed. (2005-03-01)
