now what?....bolt extractor broke too

At my work the first thing ya do is fire up the mig and put a nut over it, filler up with weld, spin it off. If that does not work, then we get the tig welder on high heat and same process with the nut over it, once its welded just spin the nut off by wrench. Never failed us yet, even with taps broken off in there. If that does not work then you gotta use a EDM machine. This thing literaly eats the target steel out of a hole with out damging the orginal threads. You do not even need to tap out the holes with it. :clap:

maybe im a redneck, but......... since you broke the bolf off in the hole a little why not screw some trheaded rod in the and nicely weld it in place. then put a nut on the outside. a setup somewhat like a head stud.

 

or is that too cheesy? :shrugani:

First try to "anneal" the extractor with a torch. Just get it cherry red and let it cool slowly. Also heat the bolt and frame around it. As every thing cools it may break loose what is holding the bolt in the first place. Then the next step if you can weld thru a nut to the bolt and extractor you can hopefully back out one or both. You anneal the extractor so the weld will hold soundly to it. If your patient then spry a little penetrating lube on the bolt,extractor and nut and give it time to work. Maybe even tap lighly on the nut to help break the bolt loose and help the lube get into the threads. Goodluck

That's about it.. lol. That extractor is hardened. You'll have to preheat it for sure to get a good weld and it still may not hold. Good luck. If you have any pics... you may be suprised what people can come up for you.

go and spend 15 bucks on a dimond tip drill bit. it will eat right thought that hardend steel. they cut through titainum like butter and that shit is hard to drill.

When you welded through/filled in the nut, then you torqued on it and it snapped off again were you just using a wrench? What if you did this but used the oldschool impact wrench; looks like a punch with a socket on the end and has a ratchet mechanism inside. You put it on the nut and hit it with a hammer. This way it is pushing inward on the bolt and trying to turn it at the same time. The shock of the impact along with the torque at the same time can sometimes work magic to get a bolt unstuck and not snap off the head. Just a thought.

well you could always strip the bike down to bare frame and chuck it up in the mill and use a carbide cutter to cut out the easy our and then if you haven't screwed up the stock threads use a thread chaser, or you can helicoil it.
