I suspect that you need to have a look at the spacer again. This should hold the speedo drive off the wheel so that when it is all tightened, the spacer is compressed between the wheel bearing and the flat face of the speedo drive. Have a look at a parts book and that description should make sense: there is a diagram in the Haynes manual too.

Forgot to say that I always get the outside nut on the speedo drive pretty good and tight, which doesn't affect the bearings at all, you should be only tightening the drive to the spacer and bearing I think, not to the wheel hub, or it would in that case, bind and affect the whole set up.
I'm beginning to remember a similar problem with one of my first Bantams, I think that the spacer was too short and as you are saying it either seized everything up or anchor plate kept trying to rotate with wheel if I remember correctly. I also seem to remember dimly I admit, that there was more than one different thickness of spacer too. Could you find some appropriate washers and try to pack the spacer out a bit more, a washer or two at a time? I think that this is your problem, David.
