Stewart Warner R-552 Radio
Restoration Case History
I was extremely excited when I won the bid on this radio on e-Bay, for
only $9.99! The seller stated that the radio worked, and that it was
in excellent condition. You can imagine how upset I was, when this
radio arrived in about 10 pieces! The seller had packaged the radio
by wrapping it in a piece of newspaper, with a couple hunks of styrofoam
to "protect" it (yeah, right). Huge pieces of the radio were broken.
Chunks of bakelite were interspersed with glass from
broken tubes. Obviously, the radio had been dropped, or had something
very heavy dropped on it. It appeared to be a total loss. However, I did have all
the bakelite pieces....maybe it could be fixed??

Broken top!
|
There's no chance the radio will work, because two of the tubes
were destroyed in the shipping process. The dial string was also
broken, so that will need to be restrung as well. There didn't appear
to be any damage to speaker cone, or any of the other components. I'm
hoping that I'll simply be able to replace the broken tubes and that
it will work, as it was advertised as working.

Broken Louvers
|
As you can see from the photos, a large portion of the top of the radio
had broken out. The photo to the left shows the damage to the louvered
section of the radio, a large chunk of which was broken out. The photo
to the far right shows the other end, which was also missing several large
chips. Not even the bottom had escaped unscathed, as it had a huge, deep
crack. I can't imagine what happened to this poor radio in shipping, but
it must have been awfully traumatic.

After removing the chassis,
I began the restoration of this radio by piecing all the broken chips
back onto the case, to make sure they would fit properly. Once I was
sure they would, then began the long process of gluing the case back
together. If you've read any of my other restoration chronicles, you'll
know that I like to use Ace 60-second epoxy to glue bakelite chips. I
slather the epoxy on quite liberally, then place the chip back into place
and hold it until it is secure (or clamp, if possible). It took several
days to glue in all the chips, as I waited for one area to dry before
beginning on another area. I used half a tube of epoxy on just this one
radio! Usually a tube will last me through 6-7 projects.

After Sanding and Glazing
|
Once the radio was glued back together, I began to sand down the case
in the areas where there were paint chips. There were A LOT of paint
chips on this radio, so the sanding process took quite a bit of time.
This also gave me an idea of what cracked areas would need more attention.
Once the case was initially sanded, I went ahead and began to apply
glazing putty to the areas which had been cracked. The glazing putty
goes over the top of the crack, sinking down into it and hiding it. Once
it is dry, it can be sanded down and painted. The photo to the left
shows the radio after being re-constructed, sanded, and glazed.
|
After Priming
|
Once the radio had been glazed, I went ahead and shot an initial coat
of primer on it. This would show me where all the problem areas would
be, and I assumed there would be a lot of problem areas! After the
primer had dried, I took a closer look. There were a lot of areas
that needed more work. The photo on the right shows the case from
the front after applying more glazing putty to the areas which still
showed damage.

After Priming
|
The photo on the left is another view of the case after the first priming,
where I've glazed areas in need. The louvered area proved to be particularly
hard to deal with, because of the intricate detail. You can see a lot of
orange glazing putty in those areas! The cycle of priming and glazing
can be repeated as many times as need be, until the case is ready. In most
cases, it takes 3-4 cycles to get everything just right (that is if you
are a perfectionist). Even then, small imperfections might show up. Because
both the glazing putty and primer dry quickly, you can do several cycles
in one afternoon. This work should always be done outdoors, or in a very
good light where the slightest imperfections will show up.
|
Painting
|
I probably went through at least 15-20 cycles of adding more glazing putty,
then priming an area. I really wanted the radio to turn out like new. The
area near the louvers took a lot of work. One of the cracks had gone through
an area which required painstaking work to get "just right". Any flaw, no
matter how small, will usually show up in the final paint if you can see it
through the primer. Eventually, I was happy with the way the radio looked, and
it was time for the final paint. The photo on the right shows the radio
getting a new paint job. I had to do several "fixes" on the radio as I did
lay on the paint a little too thick near the louvers, causing some runs.
Those areas were sanded down a bit and then I re-shot more paint over the top.
|
Finally, done..
|
Eventually, I was happy with the final paint coat. I then let the paint
cure for a few days before sanding it down and buffing it out. I wet sand
with 600 grit paper, which is just about right (400 takes off too much
paint). I usually go over the case with 1500 after the 600, as well. Then
I buff out the paint with Novus #2 polish. The end result is a smooth,
glassy finish which looks great. I then cleaned the plastic dial cover,
and the knobs. I then re-assembled the radio.
The finished radio is shown on the left.
It turned out pretty well (it better have, a lot of work went into it)!
You can't tell from the outside what trauma the
radio went through, but of course the repairs are visible from the inside
of the case.
Electronic Restoration
Two tubes were destroyed in shipping. I've got them on order. When I get
them in, I'll go ahead and replace the electrolytics, then power up the radio
and see if it works!
