Tap Removal From Ceramic Basin

[jaydebruyne]

I need to remove a tap from a large ceramic (expensive) basin. The backnut has completely corroded and is not budging. I soaked it in penetrating oil and still no go.

Room around the backnut is limited. There is a rubber washer in between 2 metal plates that go onto the underside of the tap, before the backnut.

I'm thinking, somehow of using a hacksaw to cut the backnut by going in between the 2 metal plates??? But I'm not positive I'll even get a junior hacksaw in the space...

Any other suggestions???

A hammer and chisel is out the question haha

Can't get a grinder in there, no space.. tried a socket and the nut just turns. The crosshead is what needs to come out..

First of all, it looks as if the original bolt and nut assembly hasn't been used and bodged with a cross head bolt and a nut as a packer. I've done something like this before, If you can get a cordless drill in, use a very good quality 3mm hss drill bit to drill DIRECTLY in the middle about 5mm deep, then a 4mm bit, then 5mm, then 6mm and so on until you've drill through bolt head and to the attaching threaded shaft.

Dya get me ?
