    Joel and others,

    For what it's worth, we have refrigeration on our sailboat and typically
get about five days use from two group 27's dedicated to the compressor
(Adler Barbour brand without keel cooler) by using a trick Marilyn came up
with.  We simply turn the unit off at night and back on again in the
morning.  This I might add during the summer here in SoCal.

    This is just food for thought (or is that food for thaw?  sorry) and I'm
not suggesting the same for Airstream owners but maybe some variation of our
trick might be useful some time.

Though I haven't tried it on my Airstream, I've had great luck with a stripper
I buy from a local piano restoring outfit.  There's no brand name, and I have
to buy it in gray five gallon containers with black stenciled
lettering...pretty official stuff.  It runs about $60 and comes in varieties:
thin or thick.  I use the thin for my projects, but I think I'd want the gel
for the trailer and vertical surfaces.

An aircraft stripper might be the best suggestion, though.  It's designed to
be used on stuff that sticks to aluminum.  I'll look forward to learning what
you finally find which works best.

Good luck,

Subject: Re: [VAL] 12 volt refridg

Dan, there are two different kind of 12-volt fridges. One is the usual 
Dometic type, that runs on gas, 110-volts, or 12 volts. It uses heat, 
either from propane or from an electric heating element. This kind 
really sucks up the juice. The other type uses a high-efficiency 
compressor -- the one Joann installed is a good example. Sun Frost is 
another. I had a little LeSharo that had one. It requires air 
circulation, but not the roof vent like a propane fridge does. And it is 
MUCH more efficient than the other type. Also, it gets cold really quick 
- -- from warm to ice in the ice trays in 90 minutes. These guys are great 
for folks who have an older trailer and want to replace the 110-volt 
fridge without the necessity to make a big vent hold in the roof. And I 
second what Joann said about Backwoods Solar in Idaho -- they're nice 
folks, helpful, with fair prices.

Best regards,

Rik

Subject: [VAL] Stripper for aluminum paint?

Gang,

    "Today is the tomorrow you worried about yesterday. . .
     . . . now you know why."
                                  Anonymous

I started polishing--or rather, attempting to polish--our 1960 Pacer
this week and the job has already expanded beyond what I expected.

Those of you who have seen our trailer know that the previous owner
apparently painted over the aluminum with some kind of aluminum paint. 
This paint is proving almost impossible to remove.  The paint film is
quite thin, no more than a wash in places, but hard and adherent.  I
have tried three different kinds of stripper, Bix, Martin-Senour
automotive paint stripper from NAPA, and Parks Pro-Strip, with similar
results.  Even after an hour of soaking the aluminum paint doesn't come
loose.  The paint film is softened enough that it can be removed with
_hard_ scrubbing with fine steel wool, but that's it.  (I tried a
plastic scraper, soft plastic scrubbing pads, and fine Scotchbrite, and
none of them would touch it.  Only steel wool worked, and that with
considerable effort.)

I have found that 000 steel wool doesn't scratch the aluminum too badly;
my test patches polish out OK with Nuvite F7 and the compounding
polisher.  But it's going to be awfully tedious stripping the whole
trailer with steel wool!  (Underneath the paint, the aluminum is about
what you expect on an old Airstream; pitted and scratched in some
places, and in other places practically like new.)

I tried just grinding the paint off with the compounding polisher, but
F7 Nuvite won't cut it.

In desperation I ordered some F9 Nuvite from Perfect Polish to see if
that is capable of removing the paint.  Tom at Perfect Polish suggested
trying RemovAll paint stripper.  No promises, but he says he's seen it
take off paint that nothing else would touch.  All the strippers I have
tried have been basically methylene chloride, methanol, a few other
organic compounds thrown in for good measure, and thickeners.  RemovAll
works on an entirely different chemical principle, so I can hope that it
will work where others have failed.

Has anybody used RemovAll, and can you recommend a place to get it?  Or
any other ideas to get this aluminum paint off?

(Plan Z is to paint the trailer white and rename it the White
Elephant. . . )

Best,

Subject: RE: [VAL] 12 volt refridg

Dan,
3 pair of Rolls golf cart batteries should give you about 1000amphours total
actual capacity (figure on 500amp hours so as to avoid draining the
batteries below 50%). I assume you are putting those somewhere ELSE than in
the trailer as you are talking some very SERIOUS weight.  Even with a huge
battery bank, you still have the issue that assuming you have room on your
roof for 2, 75w panels, they will be able to replace, at most, about 9 amps
/ hour of excellent sunlight.  As the Dometic 12v fridge pulls 15 amps /
hour when the heating coil is on, the only way out of the hole is hoping
that the fridge will cycle at least 50% of the time and in hot weather that
is iffy.  With a huge battery capacity as you are contemplating, you will
have 2-3 days of use even if the fridge ran 100% of the time, but the solar
panels will only be replacing a portion of the power being pulled by the 12v
fridge.  If longer term boondocking factors in, then honestly the best way
is to have a small genset, (again you need at least the Honda eu2000), to
run the fridge and charge the batteries during the day. This would also
allow you to reduce the size of your battery bank to more like a single pair
of the Rolls 6V golf cart batteries (ie about 350 amphour capacity)   

Someone else mentioned using a 12v compressor-type fridge and that is an
option, and they use less power, but they have some associated noise just as
your fridge at home.

    I am planning on having three pair of golf cart batteries with solar on
the roof.   Knowing that a 110 refridg is cheaper to purchase, and that
there should be enough storage for 2-4 days, it might be better to just go
with 110 with an inverter.  What do you think?

From: "Dr. Gerald Johnson" <geraldj@xxxxxxxxxx.com>
Subject: [VAL] Re: Batteriy capacity and refrigerators.

There is some confusion posted by David.

When using 160 ampere hour 6 volt batteries in series to make 12 volts, each 
pair is still only 160 ampere hours. Twice the watt hours, but the same ampere 
hours. So half a dozen batteries in three strings makes 480 ampere hours.

The unit "amperes / hour" is a nonsense unit. It doesn't exist. A device uses 
amperes of current (and an ampere is defined as one coulomb (charge) per 
second.) Saying "amperes / hour" is saying "coulombs / second / hour" Not a 
real unit of electricity.

A pair of 75 watt solar panels might produce 12 amperes at peak sun under 
the most perfect of conditions. Over a sunny day the total power might be 
as high as 100 ampere hours, but that's way optimistic, more likely 50 ampere 
hours is realistic without perfect weather and tracking the sun.

The 12 volt adsorption refrigerator is a power hog.

The 12 volt compressor refrigerator like the Sun Frost is economical, though it 
depends on lots of insulation of few door openings. A few years ago, 
Consumer's Reports wasn't impressed by its efficiency, because their test 
included lots of door openings which made it work as hard as a more 
conventional refrigerator design and use as much energy. Most other 
refrigerators are deficient in insulation and so can use excess energy. 
Automatic defrost adds a great deal of energy consumption but RV 
refrigerators don't often have that.

The Sun Frost refrigeration system can be bought (at least it used to) as the 
mechanics for fitting into your own box. That might be a way to repair a 
broken dometic without changing its appearance. The 12 volt compressor 
used to be listed in W. W. Grainger's catalog but assembling a refrigerator 
that way takes a lot of work.

The thickness of the insulation is always a compromise between efficiency 
and storage capacity. In our trailers the space is limited and a refrigerator 
with 4" of foam (like the Sun Frost domestic model) would be cramped for 
interior space.

It is possible to boondock without refrigeration, just means a lack of cold 
foods, and depending on canned and dehydrated foods.

Subject: RE: [VAL] NovaCool question (was 12v refridg)

Jo Ann,
Since you own a NovaCool, can you give us an idea of the compressor and
condenser fan noise levels inside the trailer?  NovaCool offers some nice
packaging options as well as low current 12V, and optional 120V operation.
Looks like from their web site that virtually all the units draw about the
same power.  Even if the unit ran 24hours a day, at 3amps, any reasonably
sized solar array could keep up & charge the batteries to boot.  The only
downside I see is on the smaller units, the freezer compartment is about 1/2
the size of the comparable freezer in a Dometic.

    The DC only frig is a Novakool R4500; 4.3 Cu ft with freezer box. 
Has a one yr warranty, two yrs on parts. Cost me $690 + shipping from 
Canada (manf there). Consumes 35 watts when compressor runs; under 3 
amps 12 or 1.5 amps 24 volt. See :
   www.backwoodssolar.com
They were very helpful to me. The key is insulation and ventilation. It 
doesn't come on a lot but that will vary with conditions and use. If 
you have little kids that are in and out of it constantly, you'll 
probably need to tow a utility trailer with banks of batteries! Good 
luck.

First off,   I'm a digester.   TRIM YOUR POSTS, like I did.

A three way fridge, uses ammonia.   The 12 VDC, 110 VAC, and propane are all
used as a heat source.   It is very inefficient as an electrical fridge, but
it is tree way.
See: http://www.rvmobile.com/Welcome.htm

If you go with a 12 VDC only fridge, it becomes much more efficient.   It
has 12 VDC motor running a compressor.   If you plug into 110, your inverter
supplies the 12 VDC.

Rolls sells offers several 6v units with capacities at or above 300+ amphour
each.  When I made my statement about a 1000amphour battery bank, I was
assuming 3 pair of the 300+ amphour batteries. And yes I know that series
connection changes nothing as far as amphour capacity and that the watthour
doubled since the voltage doubled and amperage capability remained the same.
I was incorrect technically in using amp / hour notation.  I was attempting
to convey that the 15amp load of the 12v Dometic fridge taken over a 1 hour
period is a 15amphour drain and a solar array with a 9amp output over a 1
hour period is a 9amphour capacity and that that a deficit existed that
meant the difference was coming from the batteries at a 6amphour rate (ie
eventual discharge regardless).  Of course when the Dometic cycles off, the
entire solar output can be applied to the batteries, but in hot weather the
duty cycle is typically be considerably above 50% especially if the fridge
is being opened.

There is some confusion posted by David.

When using 160 ampere hour 6 volt batteries in series to make 12 volts, each

pair is still only 160 ampere hours. Twice the watt hours, but the same
ampere 
hours. So half a dozen batteries in three strings makes 480 ampere hours.

The unit "amperes / hour" is a nonsense unit. It doesn't exist. A device
uses 
amperes of current (and an ampere is defined as one coulomb (charge) per 
second.) Saying "amperes / hour" is saying "coulombs / second / hour" Not a 
real unit of electricity.

A pair of 75 watt solar panels might produce 12 amperes at peak sun under 
the most perfect of conditions. Over a sunny day the total power might be 
as high as 100 ampere hours, but that's way optimistic, more likely 50
ampere 
hours is realistic without perfect weather and tracking the sun.

The 12 volt adsorption refrigerator is a power hog.

The 12 volt compressor refrigerator like the Sun Frost is economical, though
it 
depends on lots of insulation of few door openings. A few years ago, 
Consumer's Reports wasn't impressed by its efficiency, because their test 
included lots of door openings which made it work as hard as a more 
conventional refrigerator design and use as much energy. Most other 
refrigerators are deficient in insulation and so can use excess energy. 
Automatic defrost adds a great deal of energy consumption but RV 
refrigerators don't often have that.

The Sun Frost refrigeration system can be bought (at least it used to) as
the 
mechanics for fitting into your own box. That might be a way to repair a 
broken dometic without changing its appearance. The 12 volt compressor 
used to be listed in W. W. Grainger's catalog but assembling a refrigerator 
that way takes a lot of work.

The thickness of the insulation is always a compromise between efficiency 
and storage capacity. In our trailers the space is limited and a
refrigerator 
with 4" of foam (like the Sun Frost domestic model) would be cramped for 
interior space.

It is possible to boondock without refrigeration, just means a lack of cold 
foods, and depending on canned and dehydrated foods.

Subject: [VAL] Cargo Shifting:  Curtain track

        All,

    Well, all the curtain track replacement is complete and the curtains are
being made as I type this.  As a matter of fact, I picked up the dark, olive
green mohair cushions yesterday and they're already in place and looking
pretty darned good.  the lime green curtains with muslin liners will be
ready by mid week or earlier.  The tropical pattern shams(sp?) that were a
compromise as another family member wanted this 1940's- 50's pattern for the
curtains, will be ready for pickup tomorrow.  Yeah!

    I now have more extra curtain track than any one man should be legally
allowed to own, so it's time to share my largess with those who need some.

    If you're in the middle of a curtain track project and about to tear
your hair out for lack of material, I might be just the guy to talk to.

    I have varying lengths of three distinct types of original Airstream
track that was found in my 1969.  Some of the track was probably used in
other year models but the odd shaped 3" track with 1/4" slot for the top of
the curtains I so desperately needed, was at least in the 1968 models as
well as 1969 because I finally got mine from a 1968 and it's identical to
some of the original left in my Caravel when I bought her.

    The other styles are for use at the bottom of the curtains.  One style
has the 1/4" slot facing toward the center of the trailer, or horizontally
and the other style also has a 1/4" slot, but it faces up or toward the
ceiling.  In any event, I've have a drawing with all three shapes shown for
those really in need.  The 3" stuff is raw aluminum while the other two
styles I have are:  Some gold and some clear anodized of both styles.

    What this all boils down to is that I have a lot of track to share with
as many as I have material for, so if you really need some of this track for
your personal use, don't want it to resell for personal profit and contact
me with your requirements, I'd be more than glad to send any item length,
simply for the cost of postage.

    Talk to me,

   Wow - I really like your colors and the floor pattern - it's just 
terrific. and the woodwork and exposed pipes look really fine! So smart 
and clever. Way to go.

Yeah, Bob, you've done an outstanding job.  I really like the lavatory sink,
and I think I've finally decided what to do with the floor in mine. . . thanks
and congratulations !
