Tandem freewheel removal
Just got the first one off, was too tight for my standard method (tool in vice, wheel on tool, hands grip rim and BIG grunt).
I tried the big grunt several times, realised I wasn't willing to grunt any bigger. Took the freewheel apart, hit the body with a propane torch for a minute, and a normal big grunt worked.
And I didn't (yet) loose any of those bloddy balls, got each race's worth with a supermagnet and a ziplock bag.
