Right gents – the results!.

I inserted thick slow set cyano in each side of the horn hole and attached a new clevis to the horn. I had taken the additional precaution of squirting the clevis with household furniture polish. This was allowed to set for about an hour and a half. When I returned to the wing the clevis broke away readily and I refitted the clevis attached to the pushrod. There was appreciable less slop in the aileron but the clevis appeared to be solid on the horn with no movement showing.
I did noticed that there was a little rocking movement where the clevis was screwed onto the pushrod so I applied a drop of cyano there as well. When this had set I waggled the aileron once more and although there is still a very slight movement it is restricted to just under 1mm rather than the original 5 or 6mm.
I regard this as a definite success The second wing is now sitting with its horn being glued up at the moment.

Thank you once again for your help and opinions gents – I has been much appreciated.

Brian, do you not use lock nuts on the pushrod behind the clevis?

Yes, I usually do Robbie, however the clevises have been adjusted several times over the lifetime of the model and the locknuts are now loose. The pushrods come through a small hole and the nuts are inaccessible to tighten them up.
