Delta DP220-w/GE motor

[TejasBimmer]

Last week, I traded some stuff for my friend's Delta Slo-Speed DP220

My plan is to just replace any damaged parts, like the pulleys and wiring.
As for the motor and the drill press it does operate.
I removed some of the green paint off the motor's ID plate and saw this...

What's so cool, is that I work for GE and Schenectady is my home town.


I been searching on the web, with zero success, as to trying to figure out how old the motor.
Anyone know how to read the model code?
I am also putting out feelers within the company.

I still have not yet found any ID plate for the drill press.
I do know this came from a Houston machine shop from the 50s.
My friend inherited from his dad a decade ago.
I plan to use it for wood and soft metals.
I really would love to keep the main components original.

I suspect the motor and press are both pre 1940. Note 110 volt, not 115 volt. That style of front pulley guard is very old also. Probably get more detailed info at OWWM. org.

That definitely is not an original motor for this DP as it's in a cradle mount. Delta also did not use GE motors.

Pretty sure the slow speed drill press would have been equipped with a 1180 RPM or 885 RPM motor.

If you join www.vintagemachinery.org you can download manuals for a multitude of vintage machinery.

Cool, thanks for the tips and info.

No. That kind of option came much later, and not for that model.

The OP's drill press would have used a 1725 RPM motor, just not that GE, which is probably an old washing machine motor. The "slo speed" on the pulley guard refers to the spindle pulley, not the motor speed. There was also a "high speed" model with a different spindle pulley (and same 1725 RPM motor).

The drill press dates from the mid 1930s, somewhere between 1935 and 1937.
