....which reminds me...

My cordless drill doesn't have those handy built-in spirit levels, on
top and on the end, that are featured on some models.

It would be easy to let a couple of small level vials into the drill
casing, and glue them in with the accuracy required, so it's just a
matter of finding suitably small vials - either by cannibalizing
something else or buying them as separate 'components'.

A two-quid fence post level will provide three linear vials for the top
of the drill (one to smash while getting it out, one to smash while
letting it into the drill body, and one that's just right).

But I can't find any source of *small* bullseye levels for the rear end
of the drill. The ones in the usual electromechanical component
catalogues are too big. Any ideas, please?
