seized, broken bolt Boston
I have removed lots of broken bolts and screws from metal and wood but now have an impasse, and I will need machinist help. There are six M8 stainless bolts imbedded in a thin aluminum water jacket of a disassembled cylinder-case. Heat and strong force will ruin the case. A suggestion was to dissolve the bolt using nitric acid, I do not know about that process. A sailor friendly machine shop ( with an EDM machine ) not far from Bosston/Providence or in New England would be helpful info. Anyone?
