Some months ago there was an article in either MEW or ME (I think MEW) by a chap who was driving a fastish spindle off a vaccum cleaner for (I think) engraving.
Search as I may I cannot track down the article - can anyone out there point me to it.
Thanks,

I haven't seen the article but I can imagine it could be made to spin rather quickly if you can get the right bearings. I have a little Desoutter pencil-type air die grinder (about 3/4" diameter body) which runs a spindle speed of 80,000rpm. Very fast but not huge amounts of torque on it obviously.
If you look here

Forgot to add that if you look on the Service & Parts section there are more PDF's with exploded drawings and part numbers for spares, so this may be a further source for parts and designs.

I saw it, though I can't remember which magazine. It was around Christmas
2004 (anytime between Nov 2004 and Feb 2005). I know this because I had just been given a subscription to one of them for xmas.Best regards, Dave Colliver.
