I am planning to make some moving targets for my rifle range. I need to create a smooth 6 - 8 inch stroke to move the targets inbetween shields. I was thinking of a windscreen wiper motor but the stroke is not enough. I don't mind using electricity or air. Does anyone have any suggestions. I have tried google with little success.

Cheers, Rich.

I did think of going down that route but I have already started building the chassis. Thanks for the suggestion though.

RS componants or similar long stroke cylinder fitted with throttle(to adjust stroke speed or rodless cylinder-not cheap mind but will last years

or maybe lego technic rack and pinion if they still make them-cheaper but not as durable-also electric window winder rack mech-cant think of the right car model at mo tho

Get an old rack and pinion steering rack, and use that, couple it to a simple

cyclic pulley/ rotor and bobs your

what about a simple motor attached with 3 blade things (think windmill) then just attach the targets to the blades and you have a rotating target? You can set it up so it rotates in stages behind other objects

Didn't think about the rotating target, perhaps I'll use that on the next one! I'm liking the idea of a rack and pinion, simple to assemble and could be very robust.
