removal of pedals by spark erosion

[GrahamS2]

Oh, I'm sorry you disagree with my opinion.

 

If it would seem that splitting an atom would be an easier task than getting some busted pedals off a crankset, then I'd cut my losses and bin the whole piece.

has anybody had any experience of removing pedals by spark erosion - pedals need to be replaced urgently

Any news yet?

Did you get the pedals off?

try some Indy PR-8 Penetrating Oil, just spray and leave overnight.

Another option is Rost Off PLUS from Wurth.

so the latest in the pedal saga

took a week off from training and vowed to replace pedals. invested in Rost Off from Wurth and applied. event poured boiling water over the crank and then applied. took the removed pedals to a mate with a vice. left one wouldnt budge. while we were boiling water we tackled the RH - we 'tapped' the allen key with a rubber mallet and voila, it was loose.

the LH pedal is vas. not event my LBS was able to loosen it. so they suggested blow torch or spark eroder. i have been offered a heat gun and blow torch. imho if boiling water wouldn't 'crack' the seal would a heat gun do the trick. i'm leaning to stripping the pedal and then blow torch the spindle.
