I've been wanting "something a bit better" to replace my small benchtop drill press in my basement shop. Last weekend I spotted a 'project' drill press on the local online used listings, and grabbed it.
No motor or stepped motor pulley but otherwise OK after wire brushing off the rust.
Beaver/Rockwell Model 700 benchtop drill press - nothing extraordinary, but it does have a quill lock and a depth stop which my 'Mastercraft' lacks.
Finally I had a destination for that treadmill motor that's been under the garage bench for a few months.
So, treadmill motor, controller and tach. I already had the parts on hand as I'd thoght I was going to install that motor on my 7x14 lathe.
Nice cheap project with lots of play value. DP-$30, motor=free, AC controller=$25, Bridge rectifier= on hand but only a couple of dollars and you can salvage one from the treadmill board if you are 'stuck on a Sunday', Tach $20, small sheave for motor $10 at Princess Auto, Link belt=on hand, Hammond plastic project box=on hand .
Just FYI if you are planning a similar project: Most of the AC motor controllers are 220v units which work fine on 110v. If you want the motor to run before the (500k) pot is turned halfway, replace it with a smaller value pot. Also, the magnetic 'pickup' for the tach I have is very 'particular' about orientation and distance from the magnet so you may have to experiment a bit with your mounting setup. The good news with the one I bought is that the pickup has a small LED on the back which flashes when it's getting a good signal - this makes troubleshooting from the back of the machine easier. I put the magnet just above the stepped pulley on the drill, and used a slice from a bike tube as an elastic band and a dab of adhesive to keep it in place.

Controller: https://www.amazon.ca/gp/product/B082ML24LH/ or https://www.aliexpress.com/item/1005002074105818.html
Tach:https://www.aliexpress.com/item/1005001483922542.html? NB- It's easier if you get a tach like this one that uses AC (110v) input. Some require a separate power supply board (very cheap, but 'just one more thing')
