Your's is a neat and simple design, and a new way of gripping the slider. But, it's not a very (...) (22 years ago, 6-Jun-02, to lugnet.trains)

If you can supply an accurately timed "pulse", that would reduce the risk, but with the geared motors, it (...) (22 years ago, 7-Jun-02, to lugnet.trains, lugnet.technic)

Since it sounds like I'm not risking the motor, and I have lots of 8 tooth gears, I'm going to experiment by leaving the motor on for a while, and seeing what happens. thanks very much for the information, guys!

The bad is that it did overheat the motor, which wouldn't run again until it cooled (...) (22 years ago, 7-Jun-02, to lugnet.trains, lugnet.technic)
