Thanks! It's working very well. Since the original post, I made an adapter to hook up a hose to the end of the adapter when it's not in the spindle so I can use the pedal for blowing chips off collets, tool holders, etc.
I have no videos to show unfortunately. My video Kung Fu is severely lacking which is sad as I still have all my amateur video gear from the 80's. A big ol' Panasonic prosumer 3 chip camera with a huge hunk of glass on the front, portable S-VHS deck, couple Anton Bauer 5 AH NiCd packs, Panasonic prosumer editing deck & controller, Amiga 2000HD with genlock, etc, etc but it's all in boxes and probably wouldn't work even if I had the equipment needed to digitize & upload the now way out of date & low res images.
I'm hoping someday there'll be a revival in video gear kinda like tube amps & vinyl records so I'll be able to unload all this "vintage" equipment for a huge profit.
Methinks it's time to look around & find myself a cheap but reliable HD camera & learn some new software.
