These are old publications by the Imperial Type Metal Co. but I have found them to be very useful in understanding more about how these alloys behave. The first one is called "Type Metal Explained" and can be found here: https://books.google.com/books?id=p6...lained&f=false
The second one, also by Imperial is called "Type Metal Alloys" and can be found at: http://digicoll.library.wisc.edu/cgi...ypeMetalAlloys
I thought they were fascinating reads about this now-obsolete craft.
Thank you for the links. Began reading this evening and will read from work on the lunch hour. Enjoy reading the technical side of things and I'll bet there is some good knowledge here, the know I more about the lead alloy and with my industrial casting background the better I can dial the process in.
