I wonder also if I can't improve the chip removal a lot, by using 2 nozzles blowing air. Therefore I could get away with a less powerful air pump? That coupled with the dust hood and vacuum sucking air.. do you think this setup could give a good enough chip removal on aluminium?


What I'm not understanding is the power of the pump I'll need and if I need a tank system or not. And how big a tank. Is it a case of trial & error or are there some rules of thumb/formulas I can plan in advance?
I can just about fit everything in if I use the Wickes vac (assuming it has the same dimesnions as its dearer model. and the 6l tank shown above..


(the two nozzle system I see working well here..


PS. the hood system I'm thinking or this one
