| To RHC.{R. H. Coverley - Production Engineer} x214 Hs{Lord Ernest Hives - Chair}/Smth.3/KW.9.2.35. Bentley Conn. Rod. We have never broken a Bentley Conn. Rod, and we find that it is understressed compared with aero rods. Hs.{Lord Ernest Hives - Chair}1767 shows a lightened narrow pin rod, which should be relatively as strong at 5,000 r.p.m. as the Kestrel rod is at 3,600 r.p.m. Will you please modify an existing set accordingly, so that we may test them. Existing caps will not modify. Hs{Lord Ernest Hives - Chair}/Smth. | ||
