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.

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
bench vice
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.
