Got time in the shop this afternoon. I quickly finished turning down the shank on the second of the two carbide insert end mills, then set to work on two simple aluminum parts for Neil's RZ350 "resto-mod" motorcycle. These are among the very last of the parts needed to get the bike out on the road, two "extensions" to move the lower fairing out and way from the exhaust system. The expansion chambers he's using aren't quite stock, so some shifting of a mounting point is required.
He'll bolt these onto the existing points on the lower frame rails, then contour the tops of them to a curved shape with his belt grinder, locate a hole that will match up with one in the fairing, and tap it M6x1. These parts started as 1/2" thick x 3/4" wide 6061, a 5" long bar of it. I used the 2-axis CNC and a 7/16" two-flute solid carbide mill to run two parts on the top, then drill, counterbore and chamfer the hole. Flip the bar over in the vise, mill 1/8" off and two pieces done just needing a little Scotchbrite wheel deburring work.
