I'm afraid those distractions I mentioned seem to have been multiplying - mainly in the form of demands from grand-children. It's proving hard to find the time required, to learn the techniques of 3D modelling but I'll get there sometime !

We can wait Mike, the grandchildren can't.
Meanwhile it is a pleasure to look through your old posts (and reinstate some of the "informative" and "craftmanship" reactions that were lost with the new software). So much useful stuff in there. I think it was Martin Wynne who once tried to set up an index of all the information that hides in the many rooms of RMweb - but the task was just too big even with volunteers.
