Yes its another experimental key, (a bit further out than usual :)   some say Morse key design was over 60 years ago but its not as far as I'm concerned :)) the idea behind this key is fairly obvious the energy stored in the bent pendulum will hopefully add to the feel of the action making it more positive and lively,  the arm of the key is made of Alloy to hopefully enhance it, and the sliding weight control it, first tests are quite interesting, I've also added a spring leaf to the contacts to give the action a slightly softer feel.
