You may already know about this, but we've got a new "toy" at work
(marina/yard) and I've already put it on my "I think I need this" list.
It's an infrared (I think...) thermometer and I don't think it was too
expensive (under $50, I'm guessing). At any rate, it looks like the
trigger-type nozzle you put on the end of a garden hose, and when you
"shoot" its beam at any surface it gives you a digital readout of the
temperature.
In our shop, one of the techs was rebuilding a very large rudder and
used it to see how how it was getting inside as the resin cured, and
also to know when the cure had peaked and the temperature started
coming down. One thing he did to keep the heat down as it cured (also
in batches as you plan to do) is run a stream of cold water from a hose
on the other (non-opened up) side of the rudder, to dissipate some of
the heat.
At any rate, I've now thought of all kinds of uses for that little
thermometer - it sure looks handy.
