Or go cheaper, smaller and colder with a 'saturated - salt ice water'

Ice generally isn't "free"; salt is cheap, but also not free, and can be
corrosive to have around the shop; this is something Bob wants to run
every day (or nearly), and labor to drain the sal****er and load up the
fresh salt and ice also isn't free - so refrigeration wins, IMHO for
cheaper.

Because refrigeration is free? Really?

It also wins on less messy.

OK, I'll give you that one.

My suggestion is just something to try for a few dollars.

If it works for the duration of the project, Bob is not
out much money. If it does not work, refrigeration is
not going to work either.

One experiment is worth years of theorizing.
