The chuck 'teeth' are worn down from using it as a hole saw
and I normally remove the chuck to put a drill guide on it.

These days I can't get the chuck out to repair or replace
the head.

The usual tapping of the chuck key on the opposite side
with a mallet doesn't work anymore. It's stuck.

My directions for the drill guide say that the owners manual
for a reversible drill has the answer to this, but I have
none.

Any clues on this besides the chuck key tapping trick?

Perhaps I had the forward/reverse switch set incorrectly.

In any case I can't fix it without maybe going to Sears.

I'll see if I can find the screw.

So if I'm tapping left and holding the drill in my
left hand with the chuck facing out, does the
reversible setting make any difference?

But they must wonder what's going in in my extra room.

The place is old, the extra room carpet was shot when I got here
and there's not even a pad underneath.

But it's up on the second floor and my collection of tools
is very small. I keep the vacuum handy.

What I'd like to see happen here is a revial of the
Do It Yourself Shop. That's a place where people can come to
use tools they have no room for or can't afdford to buy
outright.

We had such a place when I was a kid-- around 1960.

I'm actively engaged in this and think it's a good project
for many towns with abandoned buildings of appropriate size.
The goal is to have the municipality purchase a space and
make it a green development project retrofitted and used
as a demonstration of alternate energy systems-- plus
whatever revenue comes in from renting time on the machines.

In this case the abandoned space is a failed supermarket close
to city center.

All properties have to have insurance: hospitals, senior centers
and businesses where machinery is used. It can't be insurmountable.

I think the interest just went away or the place wasn't
big enough or something. I have no recollection if the
Do It Yourself Shop was a chain or a stand alone business. I
was a kid. We went there for the soda machine and the
name do it yourself shop sounded like all one word to me.

I see the idea not much different from a Senior Center: a
place to go and do stuff. The senior center here was made from
an old supermarket and it's one of the best projects in town:
reuse of a private property purchased by the city, architecturally
interesting (not a dump) and performs a function.

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.
