Having just recently blown through the top of a turned lidded vessel,

from the outside makes it semi-obvious how thick or thin the walls
are. But you can't put a light inside while your working on the inside
- duh. And it's kind of a PITA to turn the lathe off, get the tool
rest out of the way, stick the light up against the opening of the
hollow form then look at the piece from the chuck side.

BUT - You Can get donut shaped fluorescent light bulbs. And if
you can fix it to the drive end of the lathe - behind the chuck
or around the chuck - and made some kind of shade - then
you might be able to use light to tell you how thick the wall
of the piece your working on is getting. Could probably turn
a "shade" even.

Brilliant idea or a dumb idea?

I use one of those cheap flexible led lights, Charlie...
Still have to stop the lathe but no tool rest moving or anything... nice for
checking some thin bowls, too...
