Adding a Variable Speed Drive to a Meddings Pillar Drill - part 1
Channel: Workshopfriend
Date: 2024-03-29

While rearranging my workshop I installed a larger 3-phase motor on my lathe which left the smaller one available for my Meddings pillar drill. I hope this will give me speed and torque control to improve drilling, reaming and tapping operations over a wide range of sizes.
In this video I repurpose a pulley I had previously refurbished by rebushing it to fit the larger motor shaft. In the course of this I also need to make a new chuck key from silver steel (drill rod).
