Re: A Dalton lathe in Italy
开云体育Wonderful to see these lathes continue to turn up. ?A pre 1915 lathe suggests it saw service in the Great War. ?Dennis May know more...The black is almost certainly Japanning. ?Jappening in the context of early early day 1915 ?lathes was a mixture of linseed oil, small amount of kerosene as a solvent, and Asphaltium. ?Asphaltium is a mineral mined in those days in a few locations in the Western US. When mixed with kerosene and lindseed oil is was reduced by heating to a liquid then painted or sprayed on the surface and baked in an oven at just under 400* F. ?Repeat three times to build up the surface thickness, and you have a crystaline, non porous surface where the mineral content interlocks to seal against water intrusion. Hence a very effective rust inhibitor. Widely used for machine tool coatings and latter by Henry ford as an undercoater in his early day automobile factories. Glenn?
