Recoring Radiator

Last year, I set out to recore a radiator. Many of the bolts came out without difficulty. But, when I got to the bolts that screwed into the cast iron header, 2 of them broke off. Then, it took me 2 hours to bore and attempt to take care of them. I cleaned the threads in one hole and was just fine. The second hole, I broke the tap off in the hole. No way to get it out except to chip chip chip until it was all broken and then the hole was boogered up real good. So, to the machine shop, welded up the hole, bored and tapped and then in business (in machine shop 1 hour) (fortunately he was my friend) So, Now I had 3.5 hours in a broken bolt plus travel time.

So today, I set out to core another one. What I did was to clip the heads off every one of the bolts that went into the cast header. Took the core out and got the header on my work bench. When I clipped the heads and removed the core, the bolts extended out about 1/4 inch. SO, I put the heat to them and with the vice grips you see in the picture, spun them all out. Entire project time by my watch 20 minues!!!! It might have worked if I had not clipped the heads off and my time would have been shorter. Isn't heat a wonderment!!!
