Looks really nice!
About two years ago, I also restored a Beomaster 4500 to sell. The mirror panel was hacked up and there was no way it could be saved.
I did find out that the panel was just a thin veneer of polished aluminum with a thin layer of mylar affixed to the surface for protection. In removing the panel, I did find sources for the gauge of #8 polished stainless steel that closely matched the top.
That was the easy part. Getting a piece cut to size was no problem.
The hard part was getting a perfect bend with a straight line crease. It looks simple, but in reality, so hard to do.
Most machine shops in the area have a hydraulic break press to put these sorts of bends in the metal. The problem is that the thin metal buckles as it is being folded. This results in a wavy crease. Not good.
Does anyone know how to get the perfect crease? For that matter, how does one get the perfect cut, where the metal doesn't roll in the direction of the cut on the edge?
If someone on this forum knows how this is done, it may be easy or possible to replicate spare mirror panels for the 4500's.
