There is one easy option , that i've used ,if you have access to a laser printer and a drawing program..
You are talking about making PCB , before etching ? right?
ok , i've done that also..
but what i was talking about was using a program like visio or similar , and a laser printer to draw the circuit on the blank board..
all you have to do is :
draw your circuit in the program.
print it onto glossy magazine paper..
iron it onto the circuit board
soak the board in water (till the paoer dissolves)
what you are left with is a board ready to be etched..
Are you talking about a milling machine which mechanically removes unwanted copper? If so, here is a homemade one. Google on "homemade pc board milling" and "homemade pc board router".
