Minor improvements in surface finish on the 122 GHz Cassegrain subreflectors. Using a larger corner-radius end mill. Seven pockets milled, just for the sheer joy of non-symmetry. Still a lot of work to do on pocket finish, deburring/chamfering/radiusing the ribs. My Fusion360 licence doesn't include the 3D debur option. Boo. Investigating whether I can use trace with a sketch path, or design-in some fillets, but that might push the cycle time from "waaay too long" towards "srsly dude?"
@g4dbn I have to admit, I have a soft spot for this "optics but with a file and sandpaper" regime :)
nice work!
