Hi Tim, Sorry for the delay in getting back to you, I have just arrived home this evening, been away since last Saturday. My lads greeted me with, guess where we found your broaches, buried in about four inches of grinding sludge in the bottom of the coolant tank on the Churchill grinder, they must have fell in when we moved everything back home a few years ago. lets hope they clean up as they look in a sorry state. Anyway many thanks for your offer. Regards Ben
