I'm back here to give the answer to the stuck chuck on
a craftsman drill problem.I went to the store.
They guy had the chuck removed in a bout 2 minutes.
Thew trick was not in using the chuck key.
What he did was use the short end of a large diameter
allen wrench in the mouth of the chuck and tighten it down.
Then a tap with a hammer got it loose.
No vise needed, no sweat. Maybe this is in the
instruction manual with new drills. I didn't have
the book.
