I set up a single multi use form tool, using some hard 1/8th rod a single first cut to rescue the diameter to .047inch then thread the bottom end 00x90

Next to reduce main rod to .103inch then using the same tool to both radius the piece and part it off at the same time.

Then the ball end was annealed by holding it in a small brass clamp with the ball and .062inch of the shaft protruding.

Next a simple v groove wooden support made to hold the flattened part horizontal for drilling the .047inch hole.
