Thanks again Geno. We read the entire thread https://www.messerforum.net/showthread.p...post378002 and it explained the Dr.'s arrival at 600C as a benchmark temperature so thank you for that. We also found support, in that same thread, of Jan's contention that temperatures higher than 600C might easily be generated and we quote;
"In some forum, somebody was very amused that I wrote in a book that you can assume the temperatures of uncooled steel up to 2000 ° C induced in the uppermost surface layers.
This person thought why then the blade does not liquefy when grinding the belt sander ...
Well it does, just in a very small area we know as a sparks rain"
There is little doubt left after reading several of these threads and studies of two things; (1) this group is very concerned about the potential for softening of the edge during the power grinding process and (2) this is a group of very smart, courteous and knowledgeable folks steeped in science and testing.
For our part we are forging ahead having ordered a bottle of 325°F Tempilaq. That's where we'll begin. We'll apply it and see what we see. We don't know, Geno, if you are a member of the German forum you reference or not but it would be very interesting to see what this group might think of our very simple experiment.
