Monopoloy Houses

Five very similar little pieces. Material is Aluminum, bead blasted to satin finish.
Most of the work work and the tapered 4-40 hole tapping done on the lathe. the angles on the mill, and hand filed and de-burred. These are almost done, just a chamfer in the tops of the threaded holes and polish on the angled surfaces and off they go. This was a fun job. They look very complicated but are in fact quite easy.

Finished posts

Finished posts. The titanium turned out to be very easy to work with. The carbide insert boring bar left a fantastic finish on the precision bored insides. The bead blaster made the nice satin finish on the outside. The 2 holes are .093 clearance for a pair of 2-56 screws. The lip of the part is a 2.5 inch radius holesaw cut of 1/4 inch away from the axial centerline.
