| E.{Mr Elliott - Chief Engineer} c. Hs.{Lord Ernest Hives - Chair} X634 BY4/G.9.2.28. CRANKSHAFT DAMPERS. --------------------- I notice in R2/M2.2.28. Mr. Royce is again reverting to the question of using cork. We have not found that agglomerated cork lubricated for friction surfaces will remain intact, it tends to break up, and for this reason we had to abandon it on the clutch for the starter motor. In place of the agglomerated cork on the starter motor we have for some long time now been using two solid discs of cork cemented to a central fabric disc with the object of strengthening up the parts. I am under the impression that I mentioned this matter to you before, and suggested that the only way I could see that cork could be reasonably used was by having cork inserts in aluminium plates. I would like to have your views on this subject. BY.{R.W. Bailey - Chief Engineer} | ||
