My books have to be 8-1/2 x 11 because of the content (cemetery censuses using Publisher & Excel). Does the jig work just as well with this size? Also, I noticed terms like 4a or a4 .... what does that mean? What is the maxium number of pages this binding method can accomodate? My books have a total of 2,400 pages (I began it in 2002!!) One local printing shop wanted $70,000 for 500 copies (3-4 volumes). I fainted and then laughed my head off. So you're a God-send, Andrew. Throughout these nine years, I've worried about the finished product. Now, with your great invention, I can finally see a successful end to this long journey -- my passion is cemeteries, counting headstones, photographing them, and digging into past histories. I'll upload my jig when it's finished. You're a brilliant and talented guy. Thanks, again.
