I found the URL for the drawing John Blacet had posted as an example of his mechanical
faceplate grid.
The URL is:
http://www.blacet.com/FPtyp.jpg
This was posted on the public Synth-DIY forum, and so far as I know passing the URL along
is permissible.
I certainly would never do anything to deliberately offend John Blacet, who is a good friend.
