I made one when I built The Ultimate Keyer Mk2 by G3RVM in the February 1980 issue of Radio Communication. I used two thin strips of copper clad board. Mine was double sided but singe sided is all that's needed. I sawed a small diecast box to get two nice right angle brackets and screwed them on the base of the main diecast box where I had the electronics. The PCB strips came out the front of the box separated about half an inch. I used stick-on rubber feet as the thumb abd finger contacts. For the switch contacts, I drilled quarter inch staggered holes in the PCBs and using the other two corners of the cut box, mounted them outside the PCBs with a long screw going through each PCB hole. So the mounts for the screws are both outside the strips. The PCB strips were nicely springy and I adjusted the screws to a very fine touch. I bought a Bencher paddle soon afterwards. I have no idea why I dismantled my own paddles; I remember their being just as good as the Bencher.
