I'm not much of a superglue user and you should probably wait for a comment from someone who is, but I seem to recall that acetone is the solvent to use for this type of glue.

Once you remove the tyres you can heat up the wheel with a soldering iron, keep the iron on until the wheels starts smoke and discolor. If you have "asbestos" fingers

you can try unscrewing the grub screw while hot or wait till cooled and it should come yust the same, DON'T breath the fumes while you heat the rim!

Loctite detatch glue remover, just apply it and wait for the glue to loosen, it works on most types of glue.

hi,
tropi's right about acetone. if you don't have any around, use your gf/wife's fingernail polish remover. In this case, it might even work better than pure acetone by wicking well and not evaporating quite as fast.

good luck!
John

A couple of tips on removing screws that are badly stuck in holes.

1. Ordinary screws.
Heat the screwdriver blade first and then hold it on the screw for a few seconds - try 5 seconds to start with. The heat will transfer to the screw and weaken any glue adhesion. Try alternately loosening and slightly tightening the screw - it will eventually loosen. If the screw is into plastic, do it fairly quickly to avoid damaging the plastic. If the screw is into metal, try a hot screwdriver first. If that doesn't work, then let it all cool down and try again cold. Consider cooling faster with a little lump of ice from the refrigerator. Alternating the hot/cold treatment will almost always 'get you out of the hole'.

2. Allen keys/hex screws/bolts etc.
First, try the above heat treatment on the allen wrench or whatever tool you are using.
Unfortunately these tools are often quite small and light by comparison with a screwdriver and therefore don't retain as much heat, so might not be as effective.
If it fails, the alternative is to use, instead, a flat blade screwdriver that is a TIGHT fit in the socket of the hex screw/bolt. If you don't have a flat blade that is an exact fit, then you can carefully file a larger one to fit exactly.
WARNING: If the fit is not good and tight, you definitely risk damaging the socket of the hex screw, so take care and only use this as a last resort, but it's a very EFFECTIVE last resort and I often use a filed blade instead of the exact tool.

3. Some people hold a fine tip soldering iron on the head of the recalcitrant screw for 2-3 seconds and this is usually VERY effective, but you do run the risk of over-melting plastic, if that is what the screw is embedded in. I prefer the previous methods first and the soldering iron only if all else fails.

Superglue debonder. However, it tends to deform some plastics (even if the bottle says it does not). Buy it at B&Q or Maplin Electronics and other sources that sell the glue. The better model stores sell it as well.

Hope nobody minds if I try a related question here: I've got an old K&B chassis where the allen screws are totally frozen due to years of corrosion. I've tried WD-40 and special "degryp" oil, but have still broken a couple allen wrench tips and turned others into licorice sticks... Will the heat method help here? Any other ideas?

Yes heat and try some light taps with a hammer on the back of the allen key or driver before attempting to loosen it. This will often break them free.

 

[Tropi]

Yes, I'd agree, hot/cold and a bit of tapping is about the only option if release oils have failed.

The opposite way works pretty good..

Superglue the allen key in, let it dry and take out the screw, then heat the screw with a lighter and ease it off into the bin, then clean the allen key.

Same advice as earlier, do NOT breath the heated superglue unless you are a cyanide addict.
