Paul,  Sorry for the confusion, but I realised last night that the counterweight is what I want to attach to.  All the spacer does is hold my flex coupling attachment plate up 20mm from the counterweight so that the plate is centered on the 50mm flexcoupling. Hopefully it is clearer now??  The ring will center on the boss on the counterweight, and in turn will center my flex coupling  plate.

Neil.

Somehow this got sent out with out my comments.

Do you have a jpg of your flex coupling?
