Ah, so you actually mean that the counterbore is 0,9, i.e. the thickness (2,5), minus the exposed length of shaft (1,6).
I'll get the verniers on one tonight and get a double check done!
(and yeah, i think it is just the washer thickness and dia that makes up the counterbore. I'll have a look and see what the easiest way to do it is.)
Gixxer, is it possible to make a few up and get them to someone local to make sure fit is ok, rather than making me a load and shipping them over? (and finding they don't fit!!)
Maybe i should just buy my own lathe..... ;o)
