Steel is fine but it might rust and look bad after a while. Make the

work with . Electrically there will be little if any differance.



And of course, everyone did use steel (once things progressed beyond
wood and bakelite chassis) right up until aluminum because readily
available and/or cheap enough, at which point I doubt anyone used
steel except if what they were building was really really heavy, ie
a kilowatt modulator or final.

I have seen a few nice layouts on Brass chassis, as well. Easier to
work than steel, and you can still solder to it. I built some tube RF
decks on 1/16" brass sheet stock, and mounted them into a steel cabinet
years ago.

I think RL Drake used copper chassis on their tube ham gear. Looked
real nice when new and shiny! I've build some equipment in home made
boxes made out of copper (you can get small pieces of sheet copper from
the hobby shop). Not cheap, but solders easy and makes a great ground
plane!

Yes, I know what you mean. I still have some pieces of sheet brass,
angles, and small tubes for RF work. I use to solder small brass boxes
together for shields when I built filters and RF pre amps. I was using
K&S Engineering materials sold at hobby shops, but the last hobby shop
in Ocala closed about four years ago. I am looking for a place to get
some deep drawn brass boxes and small tubing to build some DC blocks,
detectors, and dummy antennas to sell as alignment aids for older
radios.
