ive used a puller before, depends how badly it is siezed on! If you smake the column hard enough it should collapse and cause the adaptor to pop off BUT you gotta retighten the allen bolt holding the ignition surround on 1st 
The other way is to undo the allen bolt and also remove the bolt at the base of the column holding on the universal joint, then the entire column will come out giving better access to the ign switch screw
sounds like i wasnt hitting it hard enough then, i didnt want to damage the thread on the wheel nut or rip the bolts out holding the column brackets on.
maybe i need a lump hammer!
mates coming round monday night with the puller, hopefully that will sort things. im sick of the sight of the car at the moment so wont bother til then.
ta!
