So I picked this lump of brass up today and thought "I wonder what's hiding inside this ?"
Threw an old Myford chuck on the bed of the trusty old KX1.1 and lobbed the brass in roughly on centre.
Bit of stabbing with a 6mm cutter got it to look like this.
Swapped to a 2mm ball nosed cutter and ran the intermediate file and sure enough this was hiding inside.
Ran the finishing file which does a cut at 90 degrees to the first and got this.
Still got a few tool marks but most will polish out with a bit of wet and dry.
Could have made it better with a less value step over of the finish tool but didn't want to waste a lot of time if it wasn't going to work.
Crap video of it doing one of the final cleanup passes here.
