That Rutlands one looks interesting. It would certainly help once you got to within 1-2mm of final dimension. Until you work out how many mm's vertically a turn of the handle equates to, it's easy to over-cut...

There is not such a problem.when roughing down, so the 'ballpark' linear scale suffices there.
