[QUOTE="Nightjar, post: 301474, member: 1414"] Any older model windscreen motor is suffice. The one here is from and old Mazda has spades that can drive two speeds. Connected directly to battery with alligator clips. **If you introduce an add on speed controller you will have the overheating you have experienced.** I run the slower of the two speeds, the knocking action of the two rollers from a skate board aid the movement down the riffle box. Got my skate board rollers from an op shop for a couple of $$'s. Using a hack saw remove the aluminium housing and you be left with approx 25mm of the centre rod protruding through the roller. Length of flat bar required drill spaced holes and weld protruding rod to flat bar. The centre hole you need to drill smaller than the windscreen motor shaft then file it to fit leaving a flat to stop bar slipping on shaft. My bellows only open close approx 80 mm.
