The Unimat SL Lathe Upgrades

Video Description

In this video I upgrade the Unimat SL mini lathe by fitting a 200W motor, a Speed Controller and a Digital Tachometer. The lathe is I good condition but needed a good clean up and new bed rails. I also make two new pulley sets, one for low speeds and one for high speeds.
