This is a hub off an old Japanese bike - I want to take it apart so I can clean the rim/respoke. I can't get either side loose. It's been soaked for days in penetrating oil, heated...and sworn at. There's no rust apparent. Just 60-70 years of being together. The brake drum appears to be a right-hand thread. I would've thought it should be left-handed, given it's on the left side. But the threads say different. No idea on the cog side - but I would guess right-hand thread. I have a tool that'll span and insert two shafts into the drum's opposing holes so I can crank it. No tool for the cog side - I'm using a small punch and hammer, trying to knock it loose. No luck on anything so far. Anyone else run into something like this?
