I'm still thinking moving the table would be easier than moving the router. This is how the geometric chuck works. Believe it or not, I just broke out an old spirograph toy to play. It would be awesome to be able to make the patterns in wood. Since I can make gears, I do think it's possible. Just need to look into how it has been done before. I don't think we need to reinvent the wheel too much.

Now mount a work piece between the rails on a work table it doesn't have to be the rotary table. Now in the standard spirograph set up the stator of the mechanism would be pinned to a piece of paper. Then one of the gears would be placed inside the stator with its teeth engaged with the stator teeth. Then a pen or pencil would be placed in one of the holes in the gear or rotor. As the rotor moves the pen traces out the desired curve on the paper mounted below it. Now lets set up an arm that is attached to the router housing. One end of the arm has a stylus mounted in it and performs the task of the pen. Now if one were to move the stylus like the pen the router will move and trace out the curve. Now one could mount a pencil in the router and see if the tracing on the work piece is the same as one where the set up is perform in the traditional manner. The tracing is perform the same except it is translated by the length of the arm. It is like a pantograph with a one to one ratio. One concern I have the spirograph mechanisms normally have plastic gears. I don't know if that will stand up against the amount of force needed to move the router. The placement of the spirograph mechanism has to be registered to where the tracing is to start on the work piece. I think this will work given the restrictions I mention above. I see where Legacy was using a intricate cut template ,which had a lot of curves and holes in it, to create a copy using the router. Well that's what I had in mind. I don't know if I am pushing the approach too far. Ron -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.
