Eeeek! As someone who has spent considerable time in machine shops and
used lathes, I have to say this doesn't sound like a very good idea.
Ignoring the feasibility issues (lathe or mill, finding that big a drill
bit), there are some other problems. Even if they do manage to remove
the bottom layer of the inside of the pot, it will never be nearly as
smooth as it was. Also, the inside edge (where the sides meet the
bottom) will now be a sharp 90 degree angle, instead of slightly rounded
as it is now.
Mainly though, having working in a machine shop, I would be very hesitant
to eat off of anything that came out of there. Definitely not food grade
Interesting idea though! And since Neil already got his pot clean, I
guess we'll never have to try anything this dramatic.
btw, Neil just mentioned that he uses a small amount of oil to keep beans
from foaming and blocking the escape valve of the pressure cooker.
Though my pressure cooker's instructions say to do this, I've never found
it to be necessary at all. When I take my lid off, I always look to see
if this happened, and I've never seen it happen yet (and I've used it a
lot). Results probably vary depending on the style of pressure cooker
though, but mine isn't a particularly fancy one.
