I uploaded a little video clip to youtube showing how the repetition works.
I have also realized that the action needs no perceptible lost motion to
function well. Sorry the quality isn't better.

I discovered I could eliminate the noise of the spring by needling the
escaine (it seems like escaine) with a chopstick voicing tool. It can
conveniently be done without removing the action.
