Can't wait for more info on your machining capabilities. I'm fabbing up some mounts from 1/8" aluminum stock, but would prefer something cut from 3/16 - 1/4" aluminum plate. I'd certainly prefer to pay my money to a fellow enthusiast than a local machinist. I'll PM you some pics once I have a test mounting done.
Tomorrow I’m testing on a 1/4” piece of 6061 aluminium as my control board will finally be here ~> I’m guessing it shouldn’t be an issue to mill up to 1” with an 800w spindle (the Z height is 5” on the cnc ~> I’ll pocket-prep larger than 1” pieces for cnc milling using the drill press).
Going to try running a 2 flute (up cut) end mill; feed 10 mm/sec; 0.0625 step @ 15k rpm and go from there... will keep you posted!
