I need to make some moderately precise pieces out of plywood (birch

mill, or is there a better bit to use?

I did a cabinet for holding CDs in maple this way. Everything came out
to about
+/- .001" accuracy, and I tapped the thing together with a rubber
mallet. The mill
probably won't spin the bit fast enough, but it should work pretty well.
There might
be a little more chipping of the edge due to this.
