I know youtube isn't your thing. Joe Pie has a video that may or may not help in your situation.

How to remove a broken bolt extractor

That would be first for me! Never done a LHThread Helicoil before that I can remember.
Is it ok to post links to youtube videos?
Joe is one of the few I do watch. He has an attitude, but he does knows his stuff, so I tolerate him.
Yes, it's ok. LOL!
Just I'm no fan of YouTube. I'd rather read a book or an article, or best of all get advice from a member. But others on here seem to love it.
I missed your post somehow Chicken. I tried a carbide burr and it wouldn't touch the extractor. The extractor is prolly carbide too.
I watched a bit of the video. That's the method I normally use. But in this case I couldn't see the chamfer so I can't guarantee a good center. That's why I chose to use an extractor. Since the head is gone and there isn't any tension anymore, I figured it would come out like butter. But I screwed up by not considering that it was a left hand screw and broke the extractor. I should have known better.
Anyway, it's out now. So I'm gunna drill it out from the other side as soon as I know the screw size.
Basically, I don't know how the thread and through hole are designed. Once I know what the screw dimensions are, I'll choose the appropriate drill size and make a brass bushing to center that drill deep in the hole, then pull the remaining thread wire out, then chase the threads.
That's the plan - till poop hits the fan again that is......

Oh ya I didn't see that it was confirmed as left hand. I wouldn't be surprised if they are available although I've never seen or used one.

ONLY the hairy dude doesn't like YT videos.. everyone else here loves em... post away
It's only half confirmed. My son thinks it is. That's prolly why he broke it. But I'm hoping @John Conroy can confirm that and find out what the bolt is.
I should have done that in the first place. I'd bet big bucks the bolt is centered on the cam bearing seat. That would have made it easier to center the drill.
Not really, too many about nothing related to the search, lots could be shortened by an hour. If there was as much effert put into the video as the music and talking, would be good.
No I can't spell.

To clarify, I'm speaking about people's personally curated lists of machining videos.
Not really, I know of at least three others. But still just a small minority.
And I agree with @Bandit. If they were short and to the point, with the effort on content instead of suckling me into watching and listening to 30 minutes of garbage, I'd be more likely to watch.
I usually know what you mean, but I'm lost on that one.

I mean that most machining videos posted by members are generally well received by other members here because those links are vetted the way a curator selects only quality films for a movie festival...
otherwise a slew of YT content is just garbage.
I see..... Well I do confess that I'm more willing to give the video a try if a member recommends it. It's way better odds of a decent video.

I've used it to dissolve a tap out of aluminum, I am pretty sure that it will eat cast iron. It was made clear to me that you were to use an aluminum pan as well, as it would eat a steel one. It took about 3-4 days sitting on a rack on the woodstove, the warmer the water, the more Allum you can dissolve into it. Get it too warm, and you have to babysit it so it doesn't boil dry....... Wish that was the first method of removal I had tried, I wouldn't have messed up the start of the threads buggering around with needle nose pliers and a punch and hammer....

If I may ask a favor of you, check out what this fellow can do. No frills and fluff, just pure fascination.....
I'd watch it just on your recommendation alone. But as a favour, it would be my pleasure even if I hate it...... Here goes......
I have to admit that I watch alot of videos at 2X speed, especially when I'm just trying to get information out of it and not for entertainment. Takes a bit of getting used to but works.
