Fabricating The Rocker Arm Support

	A rocker support blank was made from 12L14 leaded steel. A chucking stub, to the left of the flange, was added for convenience.
	Rocker support chucked in a spin index in the vertical mill so features can be milled, drilled, and sawn into the blank. The spin index was mounted in both horizontal and vertical position, as needed, to complete the machining.
	Rocker support after roughing out in mill. The chucking stub is still on the part. The support was returned to the lathe, the chucking stub removed, and the support bored out so the support will fit over the inlet valve and spring..
