Geek44......you 'da man! Now that answered the biggest question for me! I thought maybe it was a different way to annotate it...decimal/comma being the same thing. It makes more sense than, het Mate, just pick 1 mm or 2 mm, whichever suits your mood at the moment! Thanks Mate!

And yes, Freights method was the one I was palnning to use anyway, as I've quickly learned (eben from my short run of build lately) that trusting the instructions for knowing what they're actually talking about is not the course of the wise Grasshopper.
