The new housing is built from 1/2" steel The ball bearing I used
is a 5/16" ID x .905" OD ( Gulf 1605-DCTN ). As long as
the ID is 5/16" the OD is not that important.
The 1/2" steel is cut larger than needed I used the original 9x mount to mark the center
I did not mark the attaching screws at this point.
Drilled a 3/8 hole. Using the mini mill and a boring head I bored the hole for
the ball bearing. The hole was bored slightly undersize to
allow for a "press fit" of the bearing.
Boring completed To mark the location for the mounting screws I first
installed 2 set screws and left the heads of the set screws
Positioned for marking the attaching screws.
