This is yet another experimental key, I wanted to build another finger key as I rather like this relaxed way of sending code, the problem I've found with this sort of key is getting the finger knob low enough and yet still retain a big key feel to the action, in this key I'm hoping to do just that by shifting the key pivot and main arm up above the knob arm, also I have fitted a duel action to this key by fitting a bar to the top of the key arm when the screw is tightened the action is hard as there is no spring at all as the knob is a direct connection to the contacts but if the screw is loosened then the natural spring of the bottom brass bar takes place as the contacts are closed which gives a completely different feel to the key, the amount of spring can be adjusted by a spring loaded nut on top of the bar, although its a really nice key it didn't quite turn out as I had hoped, also slightly over engineered I think so probably a Mk2 on the horizon as usual :()
