I think you should stop working on the Altair and sort out your workshop
wiring. Before you plug soemthing in with a serious leak and get

It is sorted.. I'm not using that circuit for my bench any longer. In fact,
it was never actually a bench circuit - I was using a different (more
spacious) table to deal with the Altair, and was powering the equipment on
that table from another outlet.
This house was built in the 1870s. The present 100A service was installed
sometime in the early 1980s, but apparently code didn't require updating of
all the outlets at that time (either that, or they just plain shirked it).
All of the "new" circuits are 3-wire, but there are still a few legacy
2-wire circuits in here - terminated in new-ish 3-wire outlets, of course.
