Nice trick, I had not thought of that. May I steal it for the web page?
I suppose it is best, if the vice has its jaws covered in hard rubber.

The only problem I have had is that if the "tap" is too brief, the winder
just gives a small hum without making an exposure. What happes is that
the motor inside starts turning, but does not go far enough to release
the shutter and activate the internal switch used to keep the motor running.
The winder operation depends on both electronic control and on switches in
both the camera and the body. My modification bypasses some of the electronic
timing, making the mechanical timing more "visible" to the user.
I expect that you will find the rythm without problems. It is not that
critical, just try the first few shots without film in the camera. It's
practically the same as a winder 2 in sequence mode.
