Details about the drill press:
This is a No. 11-120 Delta Homecraft 11” Drill Press manufactured in the Tupelo, Mississippi Delta factory in 1953. The Vintage Machinery link above has a database of all serial numbers for Delta equipment from the 1940’s-1980’s that can tell you both the year and location where your Delta tool was made just based on the serial number. This drill press was my grandfather’s that he used his whole life for every DIY project around the house. We used it together for woodworking projects he taught me when I was a kid in the 1990’s. Over the years it was painted and repainted, wiring added, and sat on a retrofitted stand with a dedicated metal toggle switch to start it up. When he passed away it sat around for a while before finally coming to me. You’ve probably seen it used in other restoration projects of mine, but the time finally came for its own moment in the spotlight.

Details about the motor:
This is a repulsion start induction motor made by the Leland Electric Company of Dayton, Ohio, USA. This motor dates to around the 1930’s or 1940’s and is not original to the drill press but has approximately the same RPM as the original motor. Repulsion start motors do not require a capacitor to start and rely on the carbon brushes that ride on the commutator to short to complete an electrical circuit in the rotor when the motor first starts. When the motor quickly gets up to speed, a centrifugal short circuiter switch on the commutator is activated and shorts all the bars on the armature and turns it into a standard induction motor. There are no bearings anywhere in this motor, only brass or bronze bushings with oil access holes surrounded by cotton (soaked in the oil) to keep the shaft lubricated and trap metal particles over time.
