I just realized something. If we use the brazing rod (URL I sent you) we can melt that in a crucible,
fill up the water jackets, machine the hole for the p-port, and now that becomes the tube WoW! that will be cool
no you can just machine a plate to hold the P-port tube onto the housing, this will eliminate the need to weld the inner rotor housing and have to do all that cleanup. What ya think?

It is worth a try. I think it will cool when you pour it into
the water jackets and not bond. However heating the rotor housing
to 1100 F in an oven and then poring the liquid brazing
stuff might work. You will have to clean out the water jacket
with a die grinder to get rid of the oxide and coolant deposits.

We don't mess with any of that in the welded p-port version.
