Hi Paul, the attached pic is a project you have been working on in the last few years. It is a departure from your design that is on the website. I notice now that the steel plate covers the
complete end of the housing. I Is the design complete? Is it practical to CNC the housing from
ALU plate. I assume the steel plate would be Nitrided. What thickness is the ALU housing, and
also the steel plate. Any specifics on the steel plate? Are IGES files available ? It seems to me
that it would be no more cost to go the CNC route, versus the whole sand cast procedure.

Thanks Again, Steve Carlisle

Later Steve :-)
Mostly yes.
