Well, it only took me... **** it took me 4 months? Well crap, didnt realize itd been that long...
Anyway, I finally finished a project! Its a miracle! Seriously though, after 4 months of this thing sitting in my shop, its finally ready to use. A quick walkthrough:
First off, a nice shot, showing off the unit as a whole. Again, thank you ryan for suggesting the perfect paint to use.
Secondly, a shot of the motor assembly. Looks a litte janky, but be respectful, a treadmill died to provide those electronics. The motor is a permanent magnet DC motor, whose label lies through its bloody teeth and claims its a 2hp. Only rated to draw 15 amps though, so in reality its closer to a 1.2hp, once you factor for the inefficiency dc motors have. Controller is an Mc-60, donated by the same treadmill the motor came from, as were all the other electronics. And before anybody points out the lack of safety, yes, i realize that all my electronics are screwed to a piece of mdf, Yes, I do know that i have a transformer uncovered at perfect poking height, and i do realize that my strain relief for all the wiring is a few staples. I also realize theres no power switch (the potentiometer turns the motor off). And no, i dont care. Eventually ill build a nice pretty box for all the electronics to sit in, and ill even add an on/off switch. Maybe ill rig up a tachometer too, but right now, it works, so i dont care.
Works pretty bloody well too. Theres some vibration at higher speeds, but i can live with that given that its a 60-some-odd year old piece of machinery with a hodge-podge of parts macgyvered together. With the 3 inch pulley on the motor run through the 4ish inch part of the stepped pulley on the quill, im getting speeds of roughly 400rpm on the low end, up to about 3-4k rpm at the high end. Thats plenty of a speed range for me, and if i need to go up or down, theres still a 2,3 and 5 inch section of the stepped pulley on the quill i can switch to, so theoretically i could get speeds anywhere from 150-10k rpm, assuming my hastily done math is somewhat correct, sort of.
Anyway, im happy. Sure, it could kill you if you lick it, and it shakes a little at 4k rpm, but it runs fine as can be at all the speeds i normally use, and drills pretty nice holes to boot. Oh, and the torque. The torque is fantastic. Overkill, maybe, but fantastic. Now i just need to replace the chuck and im golden.
