The new pieces have been produced in order to try a 1.500 bore pipe, as an alternative to the 1.625 diameter pipe shown on L.CD.165. It is intended to produce only the one set of patterns EB3477/8; the Ex.S.233/4 Induction Pipes should be made by lining the EB.3477/8 core boxes with lead to reduce the bore to 1.500 inches. Kindly instruct one set. BY/Ald.{F. Allwood - Experimental Design} Ald{F. Allwood - Experimental Design} | ||
