Archer, I was having the same problem. Taking stock of my tools at hand, this I what I did.
First, I printed Kenny's PDF. Then scanned it to a jpg at the highest RES my antique technology would allow (600 dpi). Next, into a photo editor and cropped each of the four main elements into separate jpg's. Then into my old school publishing software in the "banner" mode where size was adjusted by the scale in the software. Print and tape. Viola! Full size drawings.
