Slowing down a drill press

(1/2) > >>

Kendo:
I have an old Delta Rockwell radial arm drill press; looks like this one https://www.garagejournal.com/forum/threads/rockwell-delta-radial-arm-drill-press.439153/

But even at its slowest, it runs too fast for some jobs. Is there a mod I can make to slow down the motor? It currently has a Dayton Electric 3/4 HP motor, 1750 RPM. No telling if that's original. I was looking at variable frequency drives, and 3-phase motors, which seems like overkill. Any thoughts?

gideon:
This is cheap and might do the trick

Grumblebuns:
You need to check how many amps your drill press is pulling before using the above device. If less then 8 amps, should work.

Kendo:
My motor says 10.8A at 115VAC.

  Have you considered using a 120v dimmer switch ?
 The output side could be hooked up to a female wall outlet for quick changeover back to the original pulley speeds.  A double junction box can house both . Just add a male plug to the other end.
