Arrr, that'll explain why it didn't stay in adjustment for very long...
This is the advantage of getting someone else to build your designs before
you do :-). This I suppose also highlights the lack of metalworking
knowledge I've got.

I imagine I'll do what Scott did and go with some type of plastic packing
washer in there, and just wind it up tight. As long as the rating of the
bearings isn't exceeded, and the load forces don't compress the plastic any
more during use I imagine it will keep in good shape much better than my
copper idea.

:-), What a mouth full... I just call it the "Screw mount".

Cheers, Chris.
