Homebrew PCBs

Sticking the "tail" or joint between two half thickness spacers (strips)
forces the tail to be in the middle and the artwork aligns.

 

To use the alignment pins suggested a dedicated puncher with fixed spacing
should be used and a way to accurately align the artworks to be punched.  Of
course the fixture pins must also accurately match the punch setup.

I've always had a conceptual problem doing it exactly this way. I can
see that if the joint between the two pieces of paper is exactly in
the middle of the board thickness, every thing aligns. If it's not,
then one layer is offset with respect to the other.

Has anyone considered aligning the masks with a filler made from a
scrap piece of etched board, same thickness, and then perhaps a piece
of plastic to duplicate the board?
