I have just been given a bunch of old hand tools from a friend whose
father recently passed away. One of them is an old Miller Falls
eggbeater-type drill. It runs a bit stiff but I think if I clean up
the three gears, it should run smoothly enough.
My problem is the chuck. It seems to be frozen shut. I cannot loosen
it at all. When I try, the entire chuck begins to unscrew but the
mouth (is that what it is called?) doesn't budge.
Is there a way I can resolve this problem? The chuck is shut entirely
and there is no space whatsoever where I can even put a drill bit or
something in to help open it up.
I would really like to get the drill working and start using it!
sounds like this stash of tools is just right for setting up an
electrolysis derusting rig. it's cheap, works REALLY well, and is easy
The first thing I'd try is to clamp it in a vise with the chuck up, then
squirt some penetrating oil (e.g. Liquid Wrench or CRC 5-56, *not* WD-40) onto
the jaws of the chuck and allow it to run down inside. Repeat a couple of
times, a few hours apart, then allow it to sit there overnight, and try again
in the morning.

I use a lot of WD40 for many things, but much prefer Kroil from Kano
Labs to get corroded (rusted) items apart.
Just for the record, the jaws weren't rusted shut. I sprayed a ton of
WD-40 all over the chuck and let it sit for about 15 minutes. There
was one heck of a lot of black gunk that I assume was old oil and dirt
that came out. Once I scrubbed it with an old toothbrush and wiped it
clean, I still needed to push the jaws open the first 3 or 4 times I
loosened the chuck but thereafter, the jaws opened and closed very
So in this case, WD-40 seemed to do the trick!

Personally, I'd throw LOTS of thin oil on it and let it sit overnight...
Maybe even penetrating oil like Kroil. BUT when it was finally moving, I'd
lube the heck out of it.
I publish a website where you can find resolution to your question.
And here is specific article:
There is a section dedicated to tool restoration:
where you can find all kind of info.

Soak it for a couple of days in Kroil from Kano Labs.
