Ready Steady Eddy

[EddyCurrent]

Eddy spoke to my friend last night about this and it was exactly this reason why it didn't work well for him. It worked fine for panel work and engraving etc but was rubbish for Deep 3D work and he mainly makes casting moulds on his machine so no good.
He's played with various setups and found that the only way to deal with 3D with any decent success is to have a larger vaccum area and with big bore vacuum. The little vacs couldn't get enough volume over the larger area.!! . . . Basicly you need excess vacuum to blitz the area.
He said Small shop vac was fine for everything but deep 3D work.

Thanks, that sounds right because sometimes with deep profiles using a 6mm cutter the vac struggles to lift dust from the bottom of the slot. I have a 4" extractor but it's a lot noisier than the small one, maybe I can make two dust shoes, one for each vac.
