Clutching at straws?

The bolts are like that, they just fit loosley through the centre drum.

Ah well, pretty much as I thought, any thanks Julian. Nobody can say that I am not trying! Got to explore every possibility. Leave no stone unturned and all that.

Note quite the same but could be worth a try. When I first had the A10 the clutch actually locked up a couple of times and would not disengage. Pulled it apart and put it back together again fine until warm. The second time I spent ages with forum help going through everything trying to find what was wrong. I ended up using an old set of roller bearings I had, even though the ones in there measure the same (Vernier gauge not a micrometre).
I would try removing one roller just to see if it is because it is all to tight when warm.

PS it is still fine.

Angus, thanks for your suggestion. I will check that out, whatever it is that is going on is clearly very obscure (at least to me) so anything is worth investigating. I have nothing to lose, and much to gain.

 I just remembered.... dunno if it was Angus'issue or someone elses ,  but maybe check the length, as the issue of which I'm thinking was 1/4" long rollers (6.35) instead of 6mm long- that's enough difference to make a difference...
