Accurate spindle for light miller (was "Hiya. New to thread.")

Thanks, I'll look into using a router. The larger diameter tooling will be a
bonus too.
The nicest thing about the dremel was the speed control, I'll have to try and
implement the same thing with a router. The controller needs to keep track of
the spindle rotation position so the two should go hand in hand.
While a router will be ideal for cutting and small drilling with the materials
the machine is intended for it will still need something for drilling larger
diameters. The plan here was to pilot with the high speed spindle, then
change to an electric drill for drilling above 3mm, tapping etc.
While that will work ok it would be nice to use something accurate for low
spindle speeds. Any thoughts?
cheers
