"Elwood" the 77_remix

[N2TRUX]

One down, and one to go. I used the same method on this side, but it was destined to be a battle from the beginning. Even though I center punched the stud, the bit was determined to walk off center. I finally got adequate depth for the extractor bit and began the process of run it in, take it out and lube it again. Things were going smoothly till the tip of the extractor snapped off down in the hole.
I tried a center punch to shatter the extractor tip, with minimal progress. In frustration I found a hardened drill bit and tried to drill through. Of course that snapped off too.
Now I have the remains od the extractor and the bit in the hole.
I decided to walk away and research my options.

....so that's what they're calling it these days....

Yikes.....I've had that kind of sweet hell before......not a good time

Are you thinking Helicoil? My limited experience with broken bolts doesn't offer up much else...good luck!

Ken, I would recommend you try a smaller bolt or 1/4" round stock and weld it to the broken bolt. I usually extend the wire from a small mig out further than normal, all you need is one good tack and that bolt will come right out. A 110V mig with .023-.025 wire is perfect for that. Good luck sir

I get a feeling I will end up with a Heli-Coil insert once I'm done. Before I can do that, I have to get more of the remains out of the hole.

If it were me, and this is just me talking....I'd mask off the block and surrounding areas with some weld proof material and fill the area with weld and weld a nut onto the broken bits and get it out that way. I had to do this with 3 exhaust manifold bolts that broke off in the cylinder heads, it worked great. It took some planning, prep and patience to get them all but that was the only way for me.

Very viable options if the remains werent deep in the hole. It may come to that, but first I'm going to try a diamond tip burr to eat the hardened bit remains out.
