Hi downunder
Good comments. Thanks. Are you sure that Castor Oil does not burn till 850 F ? That seems mighty high. Back in the 60s and 70s I was involved in testing different lubricants for use in air compressors. The drip oil lubricants used on large air compressors could catch on fire at about 400 F. As I recall, the high temperature shutdowns were set at about 325 F. I don't know if we ever tested Castor oils, but we were looking for oils with high ignition points. Ah, the good old days. I'm glad they are over. Just about everything is better today. Bad manners, disrespect, and plain stupidity does seem to be up though. I am disappointed when I see it here at R/CUnivers.
