Probably a stupid idea…

   I have a bolt broken off flush with the hole, in a cast iron housing.  It’s a hard bolt, can’t drill it with the tools on hand but looking into that. It has blue Loctite on it. 

Actually had two broken ones. I welded a bolt to the first one and it worked like a charm. I’m having a heckuva time getting the second one out. Not enough hands and access and….whatever to get something welded on strong enough. 

Anyway, here’s my brain dead idea. What would happen if I cranked the current up and stuck a bolt directly into the stinger?  Would save a hand. Might work, might not. What could it hurt?

	Have you tried welding a thick washer to it then a nut to the washer?? The washer gives you more access to weld.

	When I have broken off bolts like that I weld directly on broken bolt and build up end till I can get a Visegrip on it. Sometimes it takes several tries after twisting off. Stick welder ( all I had till recently). 6013 Blob and chip.blob and chip. Heat gain will solve loctite and chipping usually helps loosen. Mostly done on Cat ex manifold studs 3/8. Nice thing about being in cast is cast don't weld well to steel so you don't have to worry about welding stud to hole. If you don't have room to work.....you have some decisions to make As far as using a bolt vs a weld rod...think you're going to find huge arc splatter with no control over puddle. Ever had a rod missing flux? Same result Edited by SteveM C/IL - 35 seconds ago at 9:01am
