Ok bit of a while since an update, fortunately summer has been both good and bad for progress. Hols with family get in the way but got some time on the machines.
Managed to make the linkages and new bearing axels spacer and bolts.
School boy error with the bolts though as both were aluminium. bare aluminium to aluminium = cold welded (bugger!)
So i found some Titanium bar ends I've had for ages and had a good day remembering to machine something interesting.
