About 15 years ago I did a bunch of PCB drilling. I used a low-cost
air-turbine. Often it goes on sale at Harbour Freight and similar places for
under $50 and the RPM is about 50,000 if I remember corectly.

It is mounted on a linear slide and activated by an air cylinder. Sorry
about the dirty appearance, it has been in storage since then.

(What did Yahoo do to the picture?? It was perfectly exposed) Any
suggestions how to avoid Yahoo destroying the pictures?
