Bob, The foundry manual I rely on is a reprint by Lindsay of the US Navy Foundry Manual for Repair Ships. A very worthy addition to anyone's library as it was written for the complete idiot to learn foundry work. Not that our sailors were idiots by a long shot, but I doubt that any of them had ever been exposed to foundry work in any form. The repair ships were equipped with a complete foundry and machine shop so warships could be repaired in the theatre of operations instead of having to sail thousands of miles to a port for repairs. Being a land lubber, I never even thought that such repair ships existed. I knew that all warships have machine shops in them, but completely dedicated repair ships??? I shoulda had oughta joined the Navy instead of Uncle's Army. Jesse MODEL ENGINEERING DISCUSSION LIST.
