So, if I understand you correctly, you nearly had an accident on several occasion because your knob was too slippery.
In the end you realised that it just wasn't going to work with a stiff box, so decided to pull it off...
To be completely clear, to do this you have to get someone to grasp it with both hands between your legs, whilst topless, and just keep on tugging?
I'm not sure superglue is a good idea though, even if your knob is broken deep inside!
Finally: :worthless:
