(...) The length of one axle is normally slightly shorter than a corresponding beam, ie. an axle #4 is slightly shorter than a 4 stud beam. So this is probably why you achieve some slack when putting bricks on either side of the axle to support it. (...) (25 years ago, 5-Dec-00, to lugnet.technic)

Amnon, I've also found a not in-significant source of friction is the bushes against the beams (or whatever your axle goes through). I've reduced this a bit on occasion by not using bushes to hold axles in position, but having a brick at each end, (...) (25 years ago, 4-Dec-00, to lugnet.technic)
