I knew an elderly ham back in the 1960s, Conrad Bridges W4EBG (now SK) in Paducah KY, who used a home-made bug.  He was a pretty good machinist, and his worked every bit as well as a Vibroplex, except he made it so it would send slower without adding a bunch of extra weights.  It was precision-built, close to a replica of a Vibroplex, not a makeshift hammy  hambone gadget made with a hacksaw blade. He never used anything but a homebrew transmitter; he even wound his own modulation transformer.  I don't know what happened to the bug, but I would loved to have got it after he died.
