Alexis, On the table of my pantograph there are 2 basic areas, the area the router can pass over, or the area the stylist can pass over. I fastened 2 short fences (about 1/2" tall), one along the front edge of the table, and one parallel with it about 10" between the two. Between these fences I lay a piece of clear plexiglass for the stylist to rub on. Under the plexiglass is where I place the printed copy (number or coloring book character). I print the number at twice the size of the number I want to route for the stylist to follow and place it under the plexiglass. I drew a pencil line on the table to indicate the center of the pivot from the rear of the table to the front of the table, so I know where to center paper with the number, and the wood I want to route. Fasten the wood that you want to route to the table using double sided tape, screws or what ever method suits you (I used wedges between two strips of wood screwed to the table). Once the wood is ready to route, the router bit is installed into the router, and the router height has to be set. If you remember the pantograph pivots up and down, as well as side to side. The height of the router bit has to cut a depth parallel with the surface, and is accomplished by adjusting the height of both the router and the stylist. I used a 1/8" straight router bit to carve my numbers for my roulette wheel at a depth of about 1/32" deep (34 numbers). To save time with set up I used long pieces of 1/4" plywood and routed the numbers to be sawn out after. With each number I moved the piece of plywood to center the number where I drew the center line on the table.
As a side note: I used a drill press when drilling all the pivot holes by stacking all the arms and drilling one end, then pinning them to make sure they stayed in alignment when drilling the next holes. I also used the pins when gluing the arms together. I made shims from a plastic milk bottle with a paper punch and scissors to insert at the pivot points.
I also have a sketchup file that I will zip and give to you (for some reason it's a read only file and it may help you make one). I usually start a project with sketchup to work out all the bugs before making something.
