Hey !! This puppy is actually quite cute !... that spring has a nice combination affect of pulling the jack back into place as well. It tensions the jack and the shank in opposite directions so to some degree it would work together with that springed jack check to improve repetition. Tho it looks like the key would need to have enough back weight to fall back quickly enough. Neat action idea.
