OK,
Stu's recent post of his Ginko bowl has me scratching my head.
I'm a Long way from needing one, but I sure would like to know How a vacuum chuck works. Obviously you apply vacuum to the plate and the workpiece is held on by the vacuum, there are vacuum router pads which allow clamp-less routing, but that I know of they have a constant source of vacuum. How the heck do you apply and keep vacuum on a bowl that is spinning at several hundred to several thousand RPM?
