Hi List,

If support is the main issue what I've done is obtain 6 foot lengths of
plastic tubing from McMaster Carr for a copule bucks. No minimums.

http://www.mcmaster-dot-com/catalog/108/html/3261.html

20 1N5408 diodes soldered in a string fit in a 12 inch length. Then I put a
hole in a rubber stopper, feed the end wire through, seat it in the end of
the tube and I have a compact 20Kv 3 amp diode. Two flat pieces of
plexiglass with holes to accept the "diodes" holds them in place to form a
nice looking compact full wave bridge. I use 2 in series (40Kv) for a total
of 8 for my rectifier. I don't pot them.
