Yea i was thinking i'm gonna need to keep things cool if i'm doing ali cuts ? i was thinking of having a vac to clear the "chips" and my compressor blowing to keep the cutter cool ?

Have you got any pics of your pump?, this cnc stuff is leading me into so many "new area's" of making things so on, i love it i wish i had tuned in at school and gone down this path for a career.

Cheers,

I have the working drawing if that's any good, the pump is up at my shop.

That's a 40mm impeller, (I just happenned to have some 40mm diam polyurethane)

I drive it with a DC motor through a variable voltage regulator, that way I get to adjust the flow using a pot on the front of the machine. Works good :D
