and this one.
interesting one this, some 2 sided in the trillions, 3 sided in the shank, and 5 sided plug cutting for the head.
cut the trillions with the flip portion of the shank and separated out.
the 5 sided plug method was nice, i love the accuracy of my mill and the ease that mach gives me for controlling Z and X with offsets.
all the parts are keyed to lock into each other after casting, see last image for the keys in the shank to take the trillion settings etc
