The first is considered by many as the bible of small shop casting and founding. "US Navy Foundry Manual" was first published in 1944, this is the newest copy published in 1958. I originally found it on an armed forces historical site it was in html, I imported it to word where its been for over ten years. Wouldn't you know it shortly after Lindsay Publications did a reprint with a colorful cover as opposed to the drab business like Nav cover.
The manual is top shelf, covers everything needed to cast good castings. Pattern making, casting design, molding, melting and pouring, metallurgy, good and bad practice and most other information you might need to pour successful castings.
Because my word doc was 344 pages I was afraid my file might be to large to upload but it is a very clean file and the pdf came in at a nice 7.4 MB. If you cast or like to read about it, you will like this file.
To download "US Navy Foundry Manual" go to my Books - Free Downloads page. # 52 - 7.4 MB - pdf
The picture of the cover is from my Lindsay copy, just to add color to the post.
