How to get it out? They are made of hardened steel, so maybe a diamond-coated drill bit? Steel frame if that makes a difference....
How did you get a bolt extractor stuck in your frame?
This sounds like the kinds of things people in A&E used to report on prior to the pandemic, involving entirely innocent accidents with unlikely household items.
You're stuffed!
When I've done this with big lumps of engineeringy stuff I've attacked it with various percussive implements (drifts/punches/chisels etc) when that didnt work I added a bit of heat and when that didn't work I had it wire EDM'd out by my friendly machine shop.
You might get lucky with a new Dormer Cobalt drill bit especially if your extractors were Chinese junk. If the extractor was a decent Dormer one then go straight to EDM.
Can you get something to fit into it and twist it out from the opposite side to the side you inserted it from?
Apart from that its very tricky
Slit the cable stop and bend it apart a bit to release it?
I would take it straight to local machine shop - my experience is you’ll just make more of a mess of it trying to drill it out. I presume this is an easy out? I threw all mine in the bin where they belong. I would only use them now where I could drill all the way through the stuck bolt. The theory is that when it snaps, as it inevitably will, you can hammer it out of the other end…
Thanks for the suggestions all.
oldnpastit – It is a second hand frame (Reynolds 953), with a cheap-looking barrel adjustor stuck in the cable stop. When I turned it with vice grips it sheared off. Then the bolt extractor I tried to remove it with snapped. The thing’s really stuck.
Probably easiest to get the cable stop removed and a new one fitted.
Thanks tthew - you've reminded me that I have a clamp-on stop lying around somewhere, that I can use while I think about what I've done.
