Another approach would be to make a transparent template using the
router
base itself, then attach the transparent template to the base you want to
drill. This was detailed in ShopNotes #85, Jan/Feb 2006 pp 5

How would the transparent base be any better for the purpose than the
router base itself?

I think the idea is that you can paste the tranparency to whatever you
are planning to mill and leave it attached during the milling process --
that way you avoid accidentally milling the real base. Disadvantage: the
real base provides you with a drill guide to assure your holes are
accurately aligned.

Not necessarily advocating so much as pointing out another method.


It's not locating the holes properly for attachment, rather locating them
properly for collet center that counts. Means you begin with collet/bit
center as your prime reference. Unfortunately, that tends to fall in the
middle of a large hole in your new base. You'd have to make an insert and
center properly on the center point to begin.
