Mast prop effects

A slightly different approach to getting a high speed spindle (spurred on by the idea of putting a speed increaser on and thinking about alternative "compact" power and coming up with air turbines to run in the spindle) it turns out you can buy high speed air spindles. I did not spend much time looking but try searching "air turbine tools - high speed spindle". You should find a fair few ideas with commercial products reaching at least 80k rpm. depending on cutter size, perhaps dental equipment? I have never seen one in use - most of what I do is at the other end of the scale
