Dean, it's probably dumb luck that the two drives on the piece I'm working on have little slack. Yet, with LEGO beams and blocks you can't use every gear combination; there are published beam/block/plate combinations that let this or that pair of (...)

There is one real simple way to eliminate backlash: Use LEGO's 'small-link chain' with their normal gears as sprockets. I paid CAN$7.00 for 135 links from Pitsco-Dacta's Canadian vendor. There is absolutely NO backlash. Mind you, the gearing problem (...) (24 years ago, 5-Apr-01, to lugnet.robotics, lugnet.technic)
