Is there a way to this?

I am trying to design a rotisserie for an oven and like a Ferris wheel I will have trays revolve about center axis on a wheel and the trays like the seats on a Ferris wheel will remain parallel to the ground. I havnt a clue how to use mates to set it up Thanks Dan

1. Insert the rotisserie part that is rotating. Start a revolute mate.
2. Select the center of the rotisserie (I use the shift key to be able to get the middle mate connector). Then select the mate connector that goes with the right plane at the origin. This allows the rotisserie to rotate about the center of the origin.
3. Insert the carriage and make a revolute mate. Select the outer portion of the rotisserie center that you want the carriage to be attached to. Then select the connection point of the carriage. This should allow the carriage to rotate about the rotisserie
4. Create a gear mate relation between the two revolute mates. Make the relation 1 so that as the center rotates the carriage counter-rotates.
5. Select the rotisserie and start rotating it. If the gear relation is correct, the carriage will stay in a relative position. If not, re-open the gear mate relation and select "Reverse Direction".

I'll try to mock something up in a bit to 1) validate my thinking and 2) explain what it is.
