Greybeard;
Shaking and Lubrication may have a lot more to do with one another than what you believe as one must remember that this pipe was supposedly made of COPPER, a metal I believe is very susceptible to vibration in thin wall applications. Altho this is not the primary thrust of my thot.
As to the Oil overheating I haven’t given this any thot at all as I do not believe this was a contributing factor in the pipe breakage. Oil chilling may or may not be the primary culprit as we will examine in the future. The ground work for this was laid out some years ago by Albert Caquot. This was started by my reading of several posts by Stephen Lawson in 2002 page #4415 permalinks # 5,6 & 8 which thoroly aroused my suspicion and distrust of the whole analysis of the so called gearbox situation. Of which I will get into at later date.
Possibly you may find the same thing that I consider a major flaw in this complete episode if you compare closely the finding of Caquot and the diary of Eastman. There are in my estimation two or three serious discrepancies in the two writings.
Yours, M. L. Anderson
