I just had this idea Jerry. Let's cast some peripheral port
inserts. Would save a bunch of hand labor and machining
on the transition from the round runner to the rectangular
peripheral port. How far along are you with a test
peripheral port engine?

Paul,...........You might as well go all the way and cast the Insert and
Injector Runner in one piece, and to put the icing on the cake supply a
Butterfly Kit for the finnishing touch :-)

I am limited to 8 by 8 inch patterns but I am experimented by bolting
several pattern fragments together. Takes a lot longer as I can do only one
8 by 8 pattern per day four days out of the week. To do a complete runner
as you suggest would require six runs of the STL machine for the out
side and six runs for the core boxes and then maybe more for the core 
prints. Does not sound too practical when most of the runner
is plain pipe.
