Paul: You, any one else, ever look at RB's aluminum end and center housings
and wonder how much trouble to machine out of solid aluminum billets for
PPort engines? After all, they won't need intake ports in them.

Can't be done because they are hollow. Now if somebody invented
a tiny robot milling machine that you could put down a small hole
and have it mine out cavities in the material that would work.

No intake ports would certainly help.

If you made them in two pieces that would also work if you could
figure out a way to seal the internal joints. Could be done with
some sort of gasket or O-rings and that is exactly what Richard
Sohn is working on.

Well, maybe great minds do run along similar tracks; but, then again, I
can't help but wonder why it occurred to me also<g> The idea of doing two
sides and sealing together or just drilling, milling and making oil and
coolant paths where necessary, plugging where necessary as well and going
from there; or, even doing thin steel sheets to fit over aluminum center
section or even furnace braze all stamped steel for each housing just seems
well worth while for those more talented than I.

I had a similar thoughts and have seen hydraulic manifolds built using two
faceplates bolted together with inside milled grooves for ports.  but I am
now wondering how much weight it would really save in this application
because you would need two aluminum plates right and these would have to be
relatively thick to avoid warping right?

Rick

Well most of the plate  would be milled away leaving
very thin walls around an 1/8th of an inch. Probably
lighter than a sand casting which must be about 3/16th
thick.
