I agree SPARKY961.Thiers lots of old info on places like the Internet Archive. Modern casting info. is all Automated High Tech. For the home caster there are a few guys Ammen, Gingery and Chastain come to mind who have published good get your hands dirty stuff the way they used to do it.Thier material is still copyrighted but if you look hard enough its out there. I have many more older books on pattermaking most are over 10 MB so I can't upload then here, but there are a few more I can upload if you want.
