I have a homemade CNC machine, moving table design, that I use mostly to cut aluminum. I have been using canned air for now to evac the swarf but it's getting pricy.

I bought some LOC-LINE flexible hoses in 1/4" (for cooland) and 1/2" for air (with assorted nozzles for lesser egress.) I just need to find the right air source and coolant pump.

Does anyone have ideas for such pumps that are cheap and easy to find. Maybe a fish tank pump would work for the coolant? Would a 120v air mattress pump be enough to evac the swarf?

Of course I will try what I have, but I thought I would throw the questions out there. I couldn't any related results after a few hours of searching. (Well, got caught up in some other threads too. CNCZone is so addictive!)


Thanks,
Colin
