It's too bad that Mark Peters is not on the list any more.
Mark is a pattern maker by trade and works at Brillion Irons Works.
He could enlighten us.

I've read some of those, Todd.  The Dave Gingery series.  That's one of the
reasons I mentioned the possibility of casting the air cleaner top out of
aluminum.  Much lower temp than cast iron.  Aluminum can be melted with a
torch; it doesn't require a cupola.

Machining the air cleaner top out of a solid piece could be done, but it
would be pretty costly.  I could get a premium for them, however... they'd
be 'billet' parts.  That's good for at least $100 extra from any hot-rodder.

I'm guessing that the Amish don't have a big presence on the internet. 
Might need to have Lane talk with them.

I do appreciate all your suggestions.  I'm still thinking about what the
best approach would be.  I admire the guys I meet at tractor shows who have
new castings for sale.  Maybe it's my turn.

For those of you not familiar with casting, what Chris was talking about was
the shrinkage that takes place when you cast a part.  The mold you start
with needs to be quite a bit bigger than the finished part you want.
 If the liquid metal solidifies at 2000 F, it will shrink a surprising
amount by the time it gets to room temperature.  Restorers allow for this by
building up the original part using Bondo before it is used to make the sand
mold.  Or they make a new, oversized part out of wood and use that to make
the molds.
