Actually, one of the first options I looked at was what you suggested: mounting the motor on the back side (under the chip tray) and run a timing belt setup. This was looking like a pretty good option, but I opted for my method due to it being more simplistic (albeit at the cost of limited travel).
Like I was telling Keith, I would be glad to share my drawings, but they are incomplete, lacking any dimensions or callouts. The are, of course, drawn accurately though, so dimensions could easily be pulled off the drawing. Given the opportunity and time, I will dimension them.
Funny, I used to be a tool designer for a living, and was very demanding of my own work. I'm really getting lazy (or maybe just too busy).
