I cut my walnut plank to size, and set it on the milling machine to drill out the holes with a forstner bit.  I have never been able to make such accurate cuts.  I am pretty happy with the results.

May 4, 2006 - My 10 z560M sockets and tubes arrived today from Hungary.  Thanks Istvan!.  The sockets and tubes fit perfectly with the machined bezels.
