yeah, very close indeed...mine called for 6 x 8 holes where as yours is 5 x 9. My original design had them all interconnected to establish pins, where as the second revision (which I shot a pic of) calls for them to be connected horizontally thus forming the "lumpy channels" which you mentioned. Right now I am working on a design using the "papermate" pen tips and offset channels. I will try to post a pic so you can tell me what you think. BTW you have a PM
