Joining of the Casting and the Steel Tube

Two production methods were considered for joining the steel tube to the casting.
Approach A -- Ream the cast hole in the fixture and press-fit the steel tube into the hole in th casting.

Approach B -- Place the tube in the mold and cast the metal directly around the tube for a direct shrink fit.
