I have the right size spanner for the RHS, but it currently will not budge, what on earth do I use on the LHS? Thanks in advance.

Help me STW, you're my only hope: Old school bottom bracket removal

Keep trying on the rhs. Once it's loosened you may be able to remove the lhs with just a big shifter.
If not you can make your own tool.
A couple of parallel pieces of suitably thick steel with a couple of other bits welded, brazed, or simply bolted to keep them in position. I used bolts, and the tool took about 10 mins to make with a hacksaw and drill.
This worked better than the special spanner I used to have for the job. Unfortunately I no longer have them - left them in Oz.

big adjustable spanner? Stilson? Get the right tool? Hammer and punch?

Plenty of plus gas overnight and a set of stilsons. If it won't loosen try tightening slightly first to get it moving. As a last resort you could try heating it up but will need repainting after. If you're using a proper spanner you could refit the crank arns with some spacers to hold the spanner onto the BB and stop it slipping off, I did something similar with an ISIS and it just means you can swing on the spanner a bit more confidently! Good luck

wot TJ said - I have a 24" adjustable spanner that serves all sorts of purposes - I think you'll get enough grip on that one flat to get it out too.

Teej - The right tool. I cannae find it, despite your fog of senility do you think you could provide a link to one?
Otherwise, its gonna be wd40, stilsons/adjustable and grunt.

As already said, a big AJ should do it. Konaboy's advise is good too.
I've had someting similar before and I found it best if you take the LH side out first.

Get the right sized spanner and then a tube (something like a piece of scaffolding pole) that you can put around the spanner to give you much more leverage. Works almost every time for me.
Also, thinking a bit more - looks like you could clamp it in a vice if you have one...

Works almost every time for me.
and the times it doesn't is when you subsequently remember that the drive side undoes the wrong way

I love the sound of metal fusing together.

oh, and do try some plusgas in there too - certainly after you get the non-drive side out.

I'd be careful with that drive side cup. You'll soon round that off with a stilson. Even a big adjustable might be hit & miss. I once ended up geting a bar tack welded onto the face of one to get it out.
Plenty of nice thin oil, & let it soak. Your local bike shop might have better version of one of THESE that should do the job. Got to be worth a bag of donughts...

takisawa2 , I have the drive side spanner, although not as good as that cyclo one..
Vice is a good idea.

Apply heat with a blow torch , plusgas and
a flat head blunt chisel and a mash hammer will see that out if all else fails !
drive side we had a special socket for it that clamped on through th shell once you had the non drive side out.
im a determined **** and no BB ever beat me - no matter how stuck.
