I have a 1930 to1950's horizontal spindle grinder and very little knowledge on using it. Its accuracy has been fine when grinding mild steel but I need to grind some O1 and it is tapering badly and even bending off the chuck plate. The stone is a 34 grit white wheel(6"). My problem arises, I think, from heat build-up as there never has been a coolant sysytem on the machine (an Australian Macson with an Eclipse chuck) nor any place where one could be easily installed. Is dry grinding O1 absolutely out of the question or are there any basic requirements to make it possible ? If it has to be wet ground what fluid is needed and do I have to buy different stones to use with fluid ? I would be most greatful for any help and suggestions.
Sorry for the oversize pic.
