Long-time-no-post.

I got the prototype manifold back from the foundry the other day, and it's
now at the machine shop for milling.  I'll post photos as soon as it comes
back.

Not bad for a first-off.  The center cores are shifted ~1/16" from nominal,
but nothing some spot weld build-up and porting won't fix.  I want to be
able to use this one.  I'll fix the pattern before any more get made.

The foundry blank came in at 7 lbs, and I suspect machining will reduce it
to ~6 lbs.

A few more pattern tweaks this weekend to get the production costs down...
apparently the molder was cussin' this one because I didn't build enough
draft into it.  Cost a lot in lost labor.
