I have an old 15" Walked turner drill press that dates back to the 40's. It's a wonderful beast of a cast iron machine, but the pulley that goes on the quill is messed up. The bronze splinned bushing inside was slipping. But I am a smart guy, and taking inspiration from the method we use to put the cam gear on a type 4 crank, I heated it up on a hot plate thinking I could then drive the bushing in tighter.
I ended up melting the largest diameter step off the pulley. (IMG:style_emoticons/default/headbang.gif) I have not been able to source a replacement. Got to thinking, since I am trying to run at a lower speed, why not just get a motor controller and turn down the speed? Any one know if this would work, and a good place for a speed control? |

I take that it's a cast aluminum pulley?
Can you machine it down and then thread and bolt on a steel weld-on style pulley with no hub? Tractor supply will likely have one. |

New (but wrong size) pulley at bottom. Could one of the proper size be attached in a way that works? Attached image(s)
