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
Great thanks for measuring that for me. 32cm x 32cm could work. It all just about fits in the space I have alongside this 24 litre air compressor.
I think I may go with this setup then. I don't think I can really get anything bigger..
I believe that 24l one is similar to your lidl one? Does it perform well enough to remove chips do you think? How long does it work for when on constantly?
JTF is cheap WTF ! <£50. That compressor should blast the chips right out of the frying pan ! I am never happy about running that type of compressor continuously. Maybe if you cut the airflow down enough to remove the swarf, but keep it as low as possible, so the compressor isn't working flat out, could work OK without burning out the motor.
My little (A4) machine is a lot less industrial, the ACO388D pump blows directly on the work from as little distance as possible as I have a nozzle fixed to the spindle mount. The air feed tube is 8mm i.d. smooth walled to keep the air flow resistance down. It keeps the chips off the cutter and I use the blower gun on the airbrush compressor to blast it occaisionally.
I plan to use a solenoid valve to pulse air when I do the steel welded machine.

Haha, cheap to the point of .. 'where's the catch'.
Apparently it's very much a 'buy cheap rubbish from China and sell in a warehouse' type set up there.. so not sure I'd trust it to perform great.. but it should give me a good idea of what I need when I buy its replacement unit! - worst case scenario. Or best case scenario, it works great and for a long time!
I guess if it fails before 6 months, I can always get a refund, assuming I'm not misusing it.
Yes your system with hose seems exactly what I want to do. As you say, keeping it as close to the cutter I think is the key. Maybe even two if I have space..
Awesome. So that's a plan then! I've been stalling on building the table until I had a plan of sorts.. so will now start it I think. Off to the timber yard...!
One thing before buying that air compressor.. I assume it's an oil filled one.. which by all accounts are less noisy and run better. However require more maintenance. However I can't seem to find any info on what maintenance it will require..
Could any one shed any light on this for me? I've never actually used an air compressor before.
I'm using a wet n dry vac from wickes works realy well and was only 40 quid , I 3d printed a dust boot I found on thingiverse it works great, first thing I've made for my 6040
