A question about how people clean / polish / treat their Aluminium parts once machined.
Assuming I don’t have an anodising plant in my shed, what do people here do to clean off the original dull faces from Aluminium plate and then corrosion protect it? I have machined mating faces so I’d rather avoid paint if I can.
I’ve had a little success with making my first Aluminium parts on the Shapeoko, machining finish is good enough for now (until I get my linear rails installed) but I’ve avoided facing most of the parts so they’ve still got the original dull and marked face from the 10mm plate;
I faced this one, it’s OK but I need to tram the machine again to get it flatter and it still wants some sort of corrosion protection;
