I see - Thanks for that.

Another question if I may - I noticed that after the circle profile cut it was uneven in a couple of places. It seems to be on the Y axis and from what I have read I think it may be backlash in that axis, does that sound right? one side of the circle it was very obvious, a slight jut out from the circle, the opposite side not so much - I wish I measured it now but I gave it to my Dad for fathers day!
