Hi,

I've got a really stubborn tap head gear that won't shift. I've tried
penetrating oil and applying heat to the tap but it won't move. I
can't get a ring spanner on it and I will be rounding off the nut or
breaking the whole tap if I keep trying with an open ended spanner.
It's an expensive and fancy mixer tap so I don't want to wreck it.

Any "magic" solutions, please?

Thanks for all the replies. I have realized now that I don't need to
shift the tap gear to fix the problem.
