Default Mag Drill Chuck Adapter

Thanks to digr, I got motivated and made an adapter for the mag drill so I could use conventional drill bits. Mine is a little different than his, but the concept is the same.

I started out with 1" CR and machined it down to .750 so it will go in the mag drill chuck. I took off a half thou so it would slide in the .750 mag drill chuck. Then I drilled one end of the .750 CR to 29/64 and tapped it to accept a 1/2" 20 TPI stud. I made the stud from 1/2" CR just long enough so it would thread fully into the Jacobs 33B chuck which is tapped to 1/2" 20 and into the adapter and not bottom out.

The adapter will need 2 flats milled so the set screws on the mag drill chuck will hold it in place. Milling not done yet, as I have no mill. The milling will come later, maybe from Bubba??????

Or, could you get a couple of dog point sets crews and drill some pockets in your fabricated shaft and go from there?

I have been known to use a cut off wheel to make those flats.

I did seriously consider doing that. I'd like to hold out a while to get the flats milled. I do not need to use it right now, so I can wait awhile. I have a base to build yet to get the mag drill up off the deck about 6" so I can use the drill with the new adapter. That will take me a few days anyway.
