I had thought the Amish didn't work cheap. Great peeps no doubt. I
hadn't expect them to get into that kind of stuff. Live and learn.
I'll check that out, and thanks for the tip/s. I *could* go as far
building a cupola furnace - what's the probability of getting decent
castings going that route? I have built a *foundry* so far, or tried
to . Pictures can be seen at

Not bad for a foist attempt I was told. *Hoped* to melt a significant
quantity of yellow brass - NOT. Very poor planning on my part. Make
that no planning.

As far as pattern making, I dunno, I thought it wouldn't be too bad.
I have a copy of "the Charcoal Foundry" by Gingery (Lindsay pubs.) and
figured that would be tutorial enough for more or less simple
patterns.

This is what I want to make (or something close):

For a one off consider lost foam casting. You make up the part
in styrafoam or urathane foam, and the runners, pack sand around
it, vent with wire or soda straws and pour in the metal. The
foam flashes and burns out. You can coat the foam with a
refactory for an even better finish.
or you can buy Lindsays pattern making books [lots of work for a
one-off]

The other Lindsay casting books are very good. I like Chastain.

The Navy casting manual that Lindsay sells is also very good.
