picked up a frame over the weekend. has a crankcase adjust bolt that goes through the back motor mount stuck in the frame. was able to remove one of them with an impact gun. no thread stripping, just most likely seized on there from heat and time sitting. the outbound side where you'd use a 19mm socket after removing the castle nut was already stripped from the shop that disassembled the bike. the inside of the bolt stripped on me last night with a 12mm hex bit. i've used heat. i took a grinder off to the edge and tried with a big ass pipe wrench. it's really stuck in there. guessing the outbound side might have been peened a bit and now is stuck.
so where can i bring this to get extracted? i'm in the south shore.
here are some pics of the bolt, so you get an idea

Drill it to round it out? Then tap it with a reverse thread and use another bolt to get it out?
Did you grit your teeth and try to look like Clint Fuckin' Eastwood?
Or did you lisp it all hangfisted like a fuckin' flower?
Maybe try heating the local area around the bolt and then spraying some duster in a can at it upside down to shock it?
You could take it to a machine shop, I'm sure they'd come up with something.
The shop would most likely just drill it out almost to the thread and then just peel it out.

Just trying to save you a trip and some money. Either way, it doesn't sound like you're understanding me correctly.
Good luck, cupcake...

If it wuz me, I'd try Harry's Machined Parts in Northborough MA.
Not So. Shore, but ...

And don't believe everything you think.
How do you think a machine shop will do it?
It's not magic.
I don't have any personal experience with them, but maybe try these guys? https://camcoracing.com/home/services/

Drool over the big block blown boat motors while you're there.
Did you try to get a couple of guys to lift it?
A man of many names...Jay, Gennaro, Gerry, etc.

maybe. i was able to extract one of those thrusters and the frame threads were fine.
i'm ok with doing helicoils. i did one on my radiator mount the other day. this would be a large helicoil though. like M21 if they even make them that large. just not something i was comfortable doing.

For those interested, the guy fixing Jim’s frame is my guy in Raynham, MA. He’s a retired machinist who has a small machine shop in his barn, he can also weld anything. He’s the “no job too small” kind of dude and is very reasonably priced. Located near the I495/Rt 138 interchange, I’ll be happy to put you in touch.
I went to MMI I know what Im doing here chief

Sometimes you gotta go the other way - cold may get it loose rather than heat:

Same idea, but with penetrant. I've have used it before and it does work. YMMV.

Late to the conversation but I would have suggested having someone tig weld a decent sized hex head bolt into it. The extreme heat from the welding process is far greater than what a torch would give while also being localized heat. It tends to open the gap between the the threads of the existing bolt and the frame section. A few seconds to let the weld set and then apply torque to the bolt head. It's what most of us have to do with those POS brake caliper bolts after somebody rounds off the hex head.
