After getting my own vacuum chuck assembled about a month ago and realizing just how invaluable it is I've decided to prepare a demo for my local club. "Setting up your own vacuum chuck on a limited budget".
It looks like Surplus Center finally sold out of the Gast G0522 vacuum pumps they've had for $54.95 (http://www.surpluscenter.com/item.as...-1669&catname=).
Anyone have another reliable source for a similar used pump?
