Hey Technic Fans, How would you connect two beams together, end to end, with one rotated 90 degrees? (URL) only solutions I can think of at the moment are big, bulky, and not feasible. I'm looking for a simple connection that will fix the two beams (...) (23 years ago, 29-Nov-01, to lugnet.technic)

Set 8082 - motorized buildign set included both a micromotor and a car with mircromotorized wheel and rack steering. The motor is simply too slow and powerless to steer in any reasonable time. The mechanism also used rubber bands (URL) (23 years ago, 28-Nov-01, to lugnet.technic)
