Thank you. First time I have seen this done. The bit I don’t understand is why do we use this V soft white metal? How is it behaving at 5000 rpm? I had an A7 special , now with a 52 TD, but I am not doing this level of work. Thanks again
the Tin or Lead is soft, but other metals are added, depending upon application, to give strength. White metals have very low friction coefficients, so are very slippery. 5000rpm are no problem. look up Babbitt bearings for more information. Glad you liked the vid!
I remember my father describing how they used to do this process and scraping it to size afterwards.... Still have some tools.... Regarding how the material will cope.... The shells even on modern engines rarely rarely touch the crank if oil pressure is enough...it will be sitting on a film of oil.
