Simple Base for Morse Code Key

I wanted to mount my Morse code key on a base so Scouts could use it at Jamboree on the Air (JOTA) this coming October. A $15 walnut “display base” from Amazon was just the right thing for that. Now we can set up a “Send your name in Morse code!” station.

The key is a CTE-26003A “Navy Flameproof” that I bought when I was first licensed, back in the early 1970’s. I’ve never used it and it was never mounted on a base. It looks brand new. The “CTE” manufacturer code is for “Telephonics”, which matches the name on the key.

A few hams offer nice bases for sale, but they were either too big or I was too cheap. This black crackle finish metal base is designed specifically for the Navy flameproof key and is reasonably priced at $30, but it is huge and weighs three pounds. Not quite was I was looking for. I also found some very nice exotic hardwood bases. Those were lovely, but I was looking for something more utilitarian.

I spotted the Plymor Solid Walnut Rectangular Wood Display Base with Ogee Edge on Amazon and chose the 6 x 4 inch size as the best match for the key. I picked up some #6 screws and fiber washers, plus some vinyl feet to keep it from scooting around on the desk.

The official Navy name for the key is “KEY SIGNALLING SEARCHLIGHT TOTALLY ENCLOSED TYPE 26003A” (spelling is original). Maybe some of the signaling searchlights were acetylene, so they needed a flameproof key. It is a very nice straight key considering that it was designed for very slow Morse code.

After I collected all the parts, I found a very similar wood straight key base project. That one uses lead shot to weight the wooden base, then felt on the bottom.
