A couple of additional thoughts You might get away with photographing the taped together pages with the outlines and then doing a bit of perspective correction in the Photoshop-like software of your choice. Keep the camera as parallel to the pages as possible when taking the photograph. Note that for either solution, if you size the bitmap to match the real world size of the pages, you can print out the result directly from the image software and compare the printed pages to the wrenches to make sure everything works.
