within the wall is REALLY DANGEROUS. Yes, the metal sinks the heat.
Where? Unless you rip the wall open, you do not know. It might sink it
to a select few places with dry old wood, or some of the awful
flammable junk that used to pass for insulation. The thermal
resistance of a metal to wood joint is much lower that that of the
hot-air to wood (or hot-air to metal, for that matter). It is easy to
get carried away with a hot-air gun (the temperature controls on those
things are not precise, as well), and you really might not know about
charring wood within the wall until too late.
As for stripping around glass on a window? Remove the glass. The putty
holding the pane is probably in need a replacement anyway.
- Heh ... you guys make a good point ... "Don't burn down the museum." :)

- Jeff J., Corey, and myself all did some museum work this week. We found
some bad news, water-wise, about our warehouse area.
Most important thing first: nothing is damaged. A few boxes are slightly
wet, etc., but that's all.
What happened is the outside roof tarp gave way in the last storm. In
response to that, Jeff J. and I last week bought several smaller indoor
tarps to cover the vast majority of our equipment. We considered this
precautionary, because other than one specific corner, there aren't any
significant leaks on the half of the building where our storage resides.
All of the bad leaks are across the hall, which is mostly empty space
right now. Those are VERY bad, but they aren't impacting our collection.
The new tarps worked -- sort of. Rather than divert any water around our
shelving units and onto the floor, they "caught" water in some puddles
atop the tarps.
Jeff was there again this past Sunday and did what he could (he was
working alone) to tip that water off the tarps and onto the floor, which
is safer than it appears, because the shelving units are all several
inches off the floor due to their wheels/legs. Corey and I did another
round of that today.
The latest weather report calls for light snow on Saturday and rain on
Sunday. Corey volunteered to go to the museum at least once a week, for
the next couple of months, to continue the process if necessary.
I went to talk to Fred about all of this. He had mixed news for us.
The town council was supposed to discuss the roof bid/contract at their
meeting tonight. Now they aren't. Apparently they have 175K put aside
for the roofs (our section and six others), but the work estimate
increased into the 200s, so they're trying to find money for it. Fred
asked the town officials, "Why can't you just do what you can now [such
as MARCH's section -EK] and finish the rest later?" ... he's waiting for
However, Fred also said he's ready and able to spend some InfoAge money
on new outdoor tarps for our building -- better ones than the previous
outdoor tarps -- and he's trying to make arrangements with the
contractor that does this work.
I'm trying to find out how much the better outdoor tarps cost. Maybe
MARCH could help InfoAge pay for it. Money tends to grease the wheels.
So, when some of you visit our storage area during Festivus (we'll do an
organized trip across campus), please "don't panic" as stated on the
cover of HHGG. It might look bad inside: giant leaks/puddles on the
empty side and possibly some small rivers between the aisles among our
shelving units. * We * put those rivers there ... it stinks, but it's
better than having the water atop our collection.
Given the cold, and the vast size of the building, there's no point in
running a small dehumidifier.
We always said that our collection, while in a building without HVAC, at
least had a solid roof, security, and a concrete floor. Right now we
really only have 2 of those 3 things. Our roof is in bad shape. The town
has the money earmarked to fix it but they're moving crazy slow.
Fred suggested that as an extra precaution we might be able to hang some
of the indoor tarps at an angle, rather than just laying them across the
top of the shelves, so they automatically divert water onto the floor. I
don't know if that will work because we have a lot of equipment in the room.
One half of our current half of the building has no leaks at all. We
just might stuff everything onto that side, temporarily, until there's a
better outer tarp and/or until the roof is fixed. I hope to avoid that
step because it would be massively inconvenient (we wouldn't be able to
get to anything) .... holding off on a decision for now.
There is also some unrelated good news.
- I heard back from "The Americans" prop folks. They're probably going
to do another rental from us after the new year.
- In the museum, Corey hung up a very nice (and extremely funny!) framed
puzzle of a cartoon computer that I built with my girlfriend, after Jeff
J. and I found it during a rescue mission several months ago. The puzzle
is colorful and looks great on our wall. Here it is a few months ago
before I framed it: http://snarc.net/puzzle.jpg and here it is now
hanging in the museum next to our IBM 1130: http://snarc.net/puzzle2.jpg.
- Corey and I also moved some clutter out of the way in the building
9059 event room where Festivus will be held. In addition, Corey dropped
off his own projecter; an Apple II+ loaded with games on a CF card; and
some adult beverages.
- InfoAge carpeted our museum hallway a few weeks ago. Much nicer than
hideous old tile! I would have preferred new clean tile, but it's still
an upgrade. Today I vacuumed the hallway and all four of our exhibit rooms.
