I've got a set of BBS-made BMW split rims that I am attempting to refurbish, but during the splitting, I've managed to shear a couple of the bolts off  which has left about half an inch of bolt sticking out of the rim... Having done a bit of research, BBS use titanium bolts, and it's likely that they were loctited in too. I've tried using Plus Gas, WD40 and a big set of mole grips but it just slips - are there any good tricks to this? |

can you get a couple of nuts on the thread to lock together tightly and get a rachet on?

I believe heat destroys loctite bonding but don't have any proof.
If you understandably don't want to use a flame try boiling water / boiling whole wheel in an cut off oil barrel over a BQQ / camp stove or a hot air gun.

quite easy I'd imagine, they do gall up quite nicely with the slightest bit of corrosion or imperfections in the threads.

Heat will sort the loctite.
Get the bolt hot
Heat it so that only the bolt stump is being heated avoiding the alloy
That way the bolt has to conduct the heat to the alloy, destroying the loctite before it damages the alloy. The alloy will also expand slightly more than the bolt so it will help increase the tolerances.
Once it's had a good heating then use molegrips on the stump and it *should* easily unscrew.
