Phantom III Connecting Rods. We send you herewith:- LeC.5330 showing the panel milling for the connecting rods. This differs only slightly from the latest rods, the cutter having a 50 slope, the object being to prolong the life of the cutters. We should like a set of rods made up forthwith and tested. With this form of milling there is a local weakening of the rod at the section marked "B" "B". LeC.5330 herewith. E/JNR.{Charles L. Jenner} | ||
