What tools did you pick up thinking you wouldn't have much use
for,
and you use all the time now?

I use the LMS 6-jaw 4" lathe chuck much more than I expected to.

It's on their #5479 5C backing plate and is easier to swap in than
removing the whole 5C setup to mount a regular chuck.

Nice looking 6 jaw. What's the worst run out you have seen across
its grip range? Honestly. grin

0.003", as specified. Electronics doesn't require the high precision
of optical tubing work like lens mount threads. My 1965 South Bend is
too worn for that anyway, and I had that job threaded on a Hardinge.

It was good enough to make the obsolete coaxial connector shell and
pin to adapt a tracking generator to my vintage rf spectrum analyzer.
