Linear track

Look at these toy rack and pinion gears. They supply two small gears that could be glued side to side for the actuator pinion, and one track, for two British pounds ($2.25) off ebay: Combining the gears like I show in the illustration below right, can increase the vertical to horizontal throw ratio: This can help turn the 530 grams of force into a greater throw with only , .43" of travel! It would take 3 sets. 10, 20, 30 and 40 teeth. The gears can double, triple or quadruple the throw.
