Help Need A Ka-Nob Trick

[Berkshire Vet]

I don't think I'm living right, because in the past week of playing with a few synchronous clocks in my 'to-do' pile, the little knob/wheel on the time set shaft refuses to come off. I'm using soft-jaw vice grips and a soft-jaw set of pliers on them. I get a good bite on the shaft with the vice grips and try to turn that doggone knob to get it off- and it just turns the shaft.. I know these are threaded right-hand, but they might as well be welded onto that shaft. There must be a way to get that off without gouging-up the shaft or even snapping it off. I've tried WD40 and no dice, I don't think it penetrates the old threads.

Thanks ahead of time for any assist.

Use Aerokroil and soak it over night and it will usually come right off.

What Wow said, I use this stuff all the time, but you must give it time to work. If that fails, apply a little heat from a small butane torch. If that fails, try turning it the opposite direction just in case it is threaded left-hand.

Whatever direction it takes to move the hands forward, the knob will likely unscrew the other direction.

You can usually hold the shaft with the flat part (at the tip) of your Visegrips without doing any damage.
