Not a very cheap guy for the viewers, first you made us all buy D-bit grinders and now have to invest for couple of other grinders😂. Some time ago I had to see what happened in a novel shape of a woodcutting circular saw teeth when chopping wood. I used a car ignition timing stroboscope synchronized with the blade. It was the scariest thing ever; the 5000rpm running blade seemed like a fully stand still item that magically took chips from the end of a 2x4". It worked quite fine with video camera too, regardless of the frame rate differences. Thanks for a great video again!

Funny enough: All those grinders I have are not a replacement for the dbit grinder - I use every one of those machines on a very regular basis :) Good hint on the car ingnition stroboscope light, I will look into that.

The strobe effect would be easy enough to implement with a Hall sensor and a configurable delay to drive a powerful LED array light, so long as the rate was far enough from the shutter rate to prevent flickering. It would be even neater to phase-lock it so you could adjust the phase lag and have a sort of manually-adjustable rotation of the image. I can't think of a way to extract the frame rate from a phone camera or my ZV-1 to synchronise the lathe VFD frequency to the camera. Nice effect!
