Subject: How to make castings for lathe

Hello,

I just purchased Dave Gingery's _Metal Lathe_ and I have several questions
about some of the casting terminology.  Here are some:

What is a draft?
What is green sand?
What does it mean to ram?
What does it mean to strike off?
What is a molding board?
What is a bottom board?
What is a roll (as in double-roll)?
What does it mean to rub in?
What is the parting face of a pattern?
What is a blank cope?
What is a false cope?

I think I know what many of these terms mean but I want to know.  Are
these these terms explained more thoroughly in _The Charcoal Foundry_? 
(As well as the casting process)  If not, could someone tell me where I
could find a book on metal casting for the beginner?

While we're at it, I don't really know anything about metal turning.  Can
anyone recommend a rudimentary book on this subject?  The bookstore
doesn't have _Lathe Work for Dummies_ <g>.

Thanks a lot,
Rob

ROB:

ALSO GET GINGERY'S OTHER BOOKS...

"CHARCOAL FOUNDRY" WILL ANSWER A LOT OF YOUR QUESTIONS.

THEN, BY ALL MEANS, GO TO MR HARNESS'S WEB PAGE.  I DONT HAVE  THE 
ADDRESS HERE BUT IT IS LINKED INTO SCOTT LOGAN'S WEB PAGES.

  http://ourworld.compuserve.com/homepages/LoganAct

WHEN YOU GET TO LOGAN THERE IS A LINK BUTTON TO HARNESS.
I'VE NOT READ IT ALL BUT THE FIRST COUPLE OF PAGES WERE REAL INTERESTING. 
 JUST WISH I HAD THE PLACE (I'M IN A MOBIL PARK) TO TRY SOME OF IT.  MY 
DAD DID SOME ALUMINUM CASTING 50 YEARS AGO.  I RECALL HIM SHOWING ME 
FLASKS, PARTING BAG, ETC...

Look at Green Sand Casting or Navy Foundry Manual from Lindsay Books 
to answer most of those questions.  The Charcoal Foundry answers some
of them.

Get the "Running a Lathe" book from Lindsay.  Either the South Bend book
or the alternate company book are good starters.  Also look for any good
school shop text.

Get thyself a copy of the Lindsay catalog and see what he has for
casting books.  I would expect (but don't know for sure) that
Gingery's "Charcoal Foundry" would cover the basic terminology.

A couple of good lathe books:  South Bend's "How To Run A Lathe,"
also available from Lindsay Publications, and "The Amateur's Lathe,"
by L.H. Sparey, a British book available from TEE Publishing in
England and some domestic sources.  (Try Coles', Saturated Steam,
Power Model Supply, etc.)

You might also check the FAQ for this newsgroup; I haven't looked
at it in a while, but some casting information is probably in there.
It at least has the names/addresses of the suppliers I mentioned.

Sorry; should have mentioned that Gingery's Charcoal Foudry book _does_ 
have 25 or 30 pages of basic sand casting instruction, and the lathe 
book assumes you've read it I guess.  Also the Bill Cannon book (more 
basic even, but covers bronze casting (not just aluminum) _and_ 
polyurethane molding (he's into auto restoration and edits a magazine: 
"Skinned Knuckles") is called "How to Cast Small Metal and Rubber Parts".
You have LIndsay info probably if you have the Gingery lathe book, but 
it's (815) 935-5353; p.o. box 538, Bradley, IL 60915.
Lindsay has a _ton_ of beginning lathe, milling machine and related 
books, including the 1942 edition of the South Bend "How to Run a Lathe" 
book and a dozen others, some more advanced.

I invested in their 750-page hardcover "METALWORKING: A Book of Tools, 
Materials and Processes for the Handyman" for $30 (1907 volume reprint) 
and found it mindboggling, covering everything from lathes (90+ pages) to 
steam and "petrol" engines, electroplating, spinning metal, _foundry_ 
(i.e. casting metals), sheet metal, tempering and hardening and  dozens 
of other things.

This book is the best thing I've bought in awhile, and if you can afford 
it, you shouldn't let the price deter you; it's like an encyclopedia on 
metal history and practice.
I have no connection with Lindsay, except as a somewhat bewildered (if 
you read  their catalog, you'll understand) but pleased customer.
