There are, or were many industrial ,water based, coolants,. I recall my first job in 1940, at The Columbus Bolt Works. They made endless auto parts, even wagon parts. Also drop forged parts. The machining, drilling and tapping methods were endless. .
The bolt headers (and rod headers) made bedlam, (Waterbury, and others )It all depended on the alloy in the parts. New cutting tools have long replaced the old ones.. And I have lost track of what goes on. We used gondola loads of coiled steel "wire" upt to 1 inch or more.The tracks into the plant area were ancient, they came off the PCC&StL next to the Ohio Penitentary. I could see the trains from the window next to my drafting table. My boss later moved me .

And old blacksmith once told me "You don't want to lubricate the cutting edge, you want just want to cool it" so he told me to use water when drilling, don't know if that would apply to tapping too. Maybe since it's so low speed it wouldn't need cooling even? ...dave __________ Information from ESET NOD32 Antivirus, version of virus signature database 5709 (20101216) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com __________ Information from ESET NOD32 Antivirus, version of virus signature database 5711 (20101217) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com [Non-text portions of this message have been removed] ------------------------------------ Yahoo!
