My stock of double sided epoxy board is a 4 ft by 4 ft sheet I bought at
a
hamfest for $20 or 25 IIRC. I have some smaller pieces left over from
the
past.
If you don't want to solder partitions or sides, you might do as I and
buy
a
10-ft length of extruded aluminum angle, 0.25 inches on a side. This way
you
can screw things together without worrying about overheating /
delaminating
the PC board. You can also take things apart if needed :-(
I'd be careful about using aluminum for this. You could set up a
situation
where over the years, the dissimilar metals would begin to react and
cause
all sorts of gremlins. I'd think you'd want to use copper or brass
angle
stock, which is also available, albeit more expensive...or plastic; or
even
wood.
You can tin the edge of the PCB and avoid this for the most part.

Probably, but the object was to eliminate heating the copper board. Other
coatings would work, as well. Zinc chromate primer is what they use in
aircraft construction.
