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.
