I seem to be having a problem putting my thoughts in proper sequence and context. Must be old timers syndrome.
Got back in the machine shop class, working on the Ball Peen Hammer Head. Just finished my rendition.

Just clamped it to the milling machine table, then center drill, drill and tap.
It’s a little tricky, clamp the piece to the table, using the slots to locate the bar. The slots also square the bar to the milling machine. Center the quill over the bar stock. The bar is parallel the the key slot. Find center using either the bar or the slot. Use a center drill to start the hole. Then tap drill the hole. Chuck up the correct size tap. Make sure the quill is not lock down. Lock down the table in both x and y directions.
Turn the quill on slow rpm and pull the quill down to contact the bar. As the quill/tap starts to penetrate the hole, turn off. Unchuck the tap. Finish by using a tap handle to continue the tapping procedure till hole is fully tapped to the bottom of the hole.
