Due to inattention on my part, I managed to strip the threads of my Campy crank where the removal tool threads in. This means I can't remove the crank arm, and naturally it's on the drive side.
Any hints how to remove it non-destructively?
I thought of an automotive pulley puller, but since the crank spider has five spindles, the pully puller won't grab.
I've tried propping the bike up and resting the spider on a couple of 2x4s and gently tapping on the bb axle with a rubber mallet and a bolt. Didn't work, and maybe I'm too afraid of bending or breaking something to give it adequate force.
It doesn't look like a job for a helicoil.
