Roger Hi, Have you had a look in your local yellow pages or thompson directory to see if there are any foundries in a fifteen mile radius of where you live. Did you manage to find the foundry information on the other list that you mentioned. I am lucky that the village that i live there is a chap who worked all his life in foundries and from time to time i can ask him for advice on patterns,core making and the sprue and risers, and the contraction allowances for different materials and sections. yours for now.
