| RHC.{R. H. Coverley - Production Engineer} X217 Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}14/KW.16.5.34. Crankcase for 4-Bearing Crankshaft. We think it would be a good idea to make some model ribs of the crankcase for this crankshaft. If therefore you would remove the ribs 2, 4 & 6 from the broken magnesium crankcase, we would then fit in plasticene ribs where we want them in order to regain the original stiffness.
