[R-390] DIY cabinet/shielding questions

[Joe Foley]

Hi Adam,

I would build the cabinet with sufficient space to
allow air circulation and put solid wooden slide
blocks on the bottom to carry the weight and allow
proper alignment of the radio in the cabinet, down
each side of the front I'd screw 2" wide by 1/8" thick
flat steel to the inside front of the cabinet to align
with the mounting holes of the front panel.  That
should secure it well enough for table-top use.

But what I'm wondering is which would look more
appropriate, raised panel sides, art deco styling, or
maybe, an overhanging top panel with LED lighting
aimed at the meters and counter.  What wood finish
would look "right" with a grey radio?  I'd almost be
tempted to make it out of maple and paint it grey to
match the radio!  That WOULD be correct for early 40's
cabinets.

Joe
