Beogram 4004 (5526): Hood Restoration

While I am enjoying listening to the Beogram 4004 (5526) that I recently finished up, there was still its scratched hood that needed a good polishing. This hood showed the usual scratching, but was otherwise undamaged. No cracks in the hinges etc..., i.e. a perfect starting point for a restoration. This shows the original condition:

I was able to feel some of these scratches with a fingernail, i.e. this hood needed an equalizing  sanding before polishing it back to translucency. Since the scratches were not too bad, I started out with 320 grit sand paper and went at the surface until all the scratches were no longer visible:

Then it was time to polish it with ever finer grit paper. After 6 steps it looked pretty good again:

Most of these hoods had rubber bumpers installed at the front corners, but they are usually broken off. I usually drill them out with a 2mm bit:

And then I glue snippets of a 2mm O-ring into the cavities:

After the glue is hardened I cut them to 1 mm length with a razor blade over a 3D printed 1mm thick washer:

This hood is ready to be installed! Soon this Beogram 4004 will travel back to its owner!
