What temp does it take to burn off the grease & grime? Looking forward to more pictures.
When I was building my 270 many years ago there was no hot tank around and a shop's steam cleaner could not remove all of the old cooked on oil & grease. I brought it home and put the Rosebud on my torch and burned it off and wire brushed the rest. It took a long time. Now it's almost that dirty again. frown
