I agree with , Ed, although thanks for the suggestions Gerald.

I just can't afford to install much more for heat than what I'm using - a
simple job site (non-vented, as you surmised) propane heater. I understand
about the source of the condensation, I just didn't expect there to be such
a difference in how the different cast iron surfaces in the shop behaved in
that environment.

I haven't seen ice yet, Ed, and my goal is to get about 5 or 6 hours of shop
time in today, but maybe I'm being too optimistic. I never thought I'd say
this, but I'd rather have 2 feet of snow than this cold f&&king temperature.
I don't physically mind it, but interfering with shop time makes me
grrrrrrrrrrrrrrrrrrrrrrrrrr.

prevent those large chunks of iron from getting so cold. Some have
tried a light bulb near the saw. I would prefer a small electric
heater blowing on it. An old electric blanket would probably work,
but might not be safe unattended.

Good advice but not very practical for most of us. The cost of heating a
detached garage for the 6 days and 18 hours that I don't use it in a week
would buy me some nice wood to work on in milder weather. When the
temperature gets to -12 like it did a couple of weeks ago, that light bulb
is not going to help much. .

Electric heat means adding new service to the garage, maybe to the house
for
the extra load. Steam heat means keeping the temperature above freezing
all
the time and is expensive to install.
