Hi,
Sorry but no. I haven't finished building the machine yet. I'm a graduate student in architecture (final year now) and I just didn't have time to finish it before things got crazy at school. I have a lot of aluminum plate cut and drilled and a 6' long piece of acme rod all sitting gathering dust while I get through this school thing. Maybe next year : )
In the end I had decided to try using a power wood chisel with a knife on it. Like this :
Foredom flex-shaft tools - Razertip Industries Inc The characteristics are similar to the oscillating knife on a Zund 1200 machine. 5000 - 15000 strokes/min , ~1/8" stroke length. It should work.
The advantage to the Foredom tool is that the motor is way off at the end of a flex shaft so you don't need to account for the weight or much of the vibration. Also the tool head is an easy 6" long and 1" diameter. All you need to do is figure out an offset motor and gear to rotate it on the c-axis... It should be relatively easy to add... once the rest of the machine is built of course. I'll get back to it after graduation.
