scrawled the following:

I am not sure why the need for so much engineering here. They sell
lathe chuck keys with built in springs, so that you need to push it
into the chuck and it falls out as soon as pressure is
released. McMaster has plenty of them.

The very same day I bought a spring-loaded chuck key for a drill press
is the day I defeated it, since I couldn't take it back. I nearly lost
a lobe off the chuck as it slipped out of place while I was tightening
the chuck, and that was it. They're dreadful, Ig...Absolutely a pain
in the freakin' ass! You've obviously never used one, or the one you
used had a -very- weak spring. Most are antithetical to use.
