Alf,

Thanks for the answer. I am considering a Taig CNC mill but I was also looking at a small cnc router from ImService. Here's a link to the router:

I thought the router might be a better choice for carbon than the Taig, but I have no experience with machining carbon so I don't want to buy the wrong machine...

When you say Doug, are you referring to Doug Powell?

Thanks again,
David
