A Design Study in Steel - Crossbleed Valve for the F-5

Option A -- Thinner Shaft 

In Option A, the shaft is made thinner so there is less mass and the shaft will cool and solidify more quickly.

This option does not guarantee that the shaft will be free of shrinkage, because flow into the center shaft is still remote from the metal source.

More critically, the thinner center shaft compromises  the strength of the valve body and provides insufficient space for the valve linkage.

The "thinner shaft"  is not a good approach because it compromises the functionality of the valve body. 
Go back and select another approach.
