How do I adapt my spiral ratcheting screwdriver to use with all bits?

I'd try to join one of your existing bits to a 1/4" socket. Maybe the slot will fit nicely into the 1/4" drive side of the socket? A bit of file work should get you to something pretty firm. Then ...

Drill bit stuck behind chuck

How do I remove a chuck that got stuck during removal?

The last time I removed a chuck like that, I had to open the jaws and remove the screw that was down inside the chuck... And, sadly, they are usually "munched" due to the drill bits that have turned ...
