Can't imagine that plate is flat enough to be useful and could cause you more trouble than it's worth.?

Personaly I would just buy Machine tooling plate that is ground perfectly flat. Put your Profile etc directly on this and then shim out any error using the nice flat surface for reference. No need to skim flat. Then you can drill tap matrix of holes. Forget tapping with router type spindle no where near enough torque or control to do this unless thread milling. It's nothing of job to do with spiral flute tap in a Cordless drill.
