Homebrew PCBs

Hello all,

I see there has be some talk about PCB Milling machines, and I was 
wondering are there any plans so far?  I would like to 'mill' my PCB 
now as the old way is getting to dangerous and costly as for EPA 
standards.  I live in an apartment complex and the codes about 
chemicals are very harsh.  So I want to see if there are any plans in 
the works to build a PCB mill.  

I did check out the one from RoboShack, but no plans as of yet.  

So, is there any one with plans to biuld a PCB Mill?  If so can any 
one get a copy of them?  

Let me know,

Jon Bevar
