PCB Milling reccomendations

[magicniner]

This is the attitude that I like to hear! I have discussed a hand mill with colleagues and due to the parameters that we would have to work with wouldn't be an option, nobody here would trust themselves eyeballing the depth going through the PCB.

You don't eyeball, you fit a DRO to the Z axis (digital caliper bodged on is popular) and measure the PCB thickness, set zero for the lower surface and you're good to go for precision depth milling ;-)

You mentioned about being able to CNC it within budget, would this be with the chinese cnc machines found on ebay?

Crikey No! They're Shite! If the Proxxon does the job manually just add steppers, drivers etc.
To cut down on leg work you could look for something like -

Not saying that one is any good but read reviews and Google around a bit and preferably find a supplier you can visit if things are going particularly Pete Tong ;-)
