I know this is a dumb question, but I have to ask. Is there any magic to removing the spanner nuts on the back of the spindle? I want to replace the gear in front of the pulleys with an optical disc. I've put so much torque on the nuts the slots are starting to distort, and they still won't budge. I'm basically just holding the inside nut and trying to turn the outside nut CCW. Nothing. Are they reverse threads??
Thanks,
Jeff
