looking for a cheap high speed cat 40 or stright shank electric or air spindle
I was going to try to make one with a mini wood router just no time but have a engraving job and our mill only has 4000 rpm spindle and have to use a 1/16 end mill.
its only a 800 dollar job but can always use it for other stuff
any one have any ideas ?
thanks john

BIG or other brand "speeder". They multiply your spindle speed. There's also a Vulcan air spindle (jig grinding attachment) with various straight/taper shanks.

I'd be interested in seeing the pics - how did you mount the router to your spindle?

[victorofga]

im willing to bet with ducktape :-)

sorry...

seriously im also curious.. becuse regular spindles spinning relatively slow compared with engraving spindles..

[redridertwo]

no ducktap
just bunggy cords lol

[victorofga]
