I'm also thinking about trying some aluminium and wondering do I need a mister, or at least air blast to do anything more than minimal work in aluminium? Or would the dust collection remove chips enough?
I have one of these basic eBay misters https://cdn.thingiverse.com/assets/f..._Collar_02.png but no compressor yet as most things I read suggest you need a fairly decent tank size to prevent overheating.
I also looked at silent "dentist type" however the price goes up a fair amount!
Any advice from those who have "been there and tried that" :)
Different grades of alli will cut differently. 6082T is generally ok or 7 series and cast alli . just spay a bit of WD40 or equivalent helps but if you get the feeds and speeds correct it will cut fine.
