Alright, I tried the bb and super glue idea...

(closed)
So, I was looking for a method to prevent theft seeing as I live in a not so great area in a populous city. I read about the ball bearing and super glue idea and how you can remove with acetone and some patience.
I put superglue, then the BB on top, then more superglue on top and let dry months ago. Worked fine. Now I go to change handlebars.

Problem is... I can't get at the super glue beneath the ball bearing. I applied acetone in small bursts (it dries fast) over and over for an hour. With that I was able to remove all the superglue on top of the BB but couldn't get the stuff underneath. I then set for over 1 hour and 45 minutes with the stem face and bolts soaking in a dish filled with acetone, hoping the acetone would slowly eat within the cracks. No go.

Then I read the melting point of superglue is somewhere below 400 degrees... okay, fine.
I got my butane lighter, which burns pure blue. Butane lighters are supposed to burn much hotter than 400, but no go there as well.

Any ideas?

Oh, and before you say I can just remove the stem and throw out or something, I'm an idiot and did the same thing to my headset...

wax dude, superglue is such a huge pain in the asshole to deal with. seems like you might just be stuck unless you wanna find an acetylene torch or something like that

Yeah, I mean the top cap. lol
Acetone didn't work.
Hammer and poker didn't work
Soldering iron... nope.

I'm looking to have the top cap cup off. Then the stem can come off. I can cut through the bolts if I still want the stem, but it's a cheapo I as planning on replacing anyways. I was also planning on getting the steerer tube cut down as well...

LoL too much... Just use a security bolt for your topcap. With 3d printing you can make your own bolt and tool as well.

Depends how good you are with a centre punch & high quality drill (and it will need to be high quality as bolts are hard) - but you can cut the top cap off then drill the reverse ends of the stem bolts 3 mm diameter to a depthof, say, 10 mm. Then, tap the holes M3 then screw in an 15 mm long M3 allen head bolt. So long as you haven't over-torqued the stem bolts, once the M3s are bottoming out, the force you are putting on them from the reverse end will then be unscrewing the stem bolts, Hold the head of the original stem bolt with pliers, release the M3 bolt with the allen key then unscrew the original bolt with your fingers.

Have I done this? Yes I have, a few times.
Is it a faff? Yes it is - but:
1) no risk of catching the fork column with the saw cutting the clamp bolts and
2) if you heat that area to anything like 400C you will compromise any heat treatment of the stem and / or the fork column and that might have really bad consequences.

Next time - use silicone and no ballbearing, no superglue! You can dig the silicone out with a dentist's pick, if you ever need to ...

Methyl ethyl ketone - like acetone. But muuuuch stronger. It'll get it out I promise you.

If all else fails you can (carefully) use a drill with cobalt bits to drill the head off the bolt. Use plenty of cutting fluid.
