Re: [CAD_CAM_EDM_DRO] Vacuum Table

Tim, Bill,
I just got a flyer from MECI (Mendelson's in Dayton, OH 800-344-4465)
with a sale on:
"High power vacuum motor Assy's, 120VAC, 12A, 5-3/4" dia x
5-1/4" long Mfg. Mossler, designed to used in vacuum tube message
systems" p/n 420-0579 $24.95 These are bare motor units
with the vacuum unit attached directly like a shop vac.
