I want the instructions for the big RoboRiders, but they can apparently no longer be found at lego.com. I tried to load the smaller riders, but they are all one big error. Are these on brickshelf or anything? (25 years ago, 5-Dec-00, to lugnet.general, lugnet.technic, lugnet.build)

I have build 2 of these machines, this is a nice set, but I have a two complaints about this set. 1. the flex stearing system does not respond good. 2. the mechanisme to transfer the motor to the wheels is a sloppy, there are 5 chains with each 16 (...) (25 years ago, 4-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)

One of the tough problems in building a clock is to design a very low friction, very tall gear ratio drive. I want the spool to turn around somewhat less than once every half hour, and the escapement to turn once every six seconds, so I need around (...) (25 years ago, 4-Dec-00, to lugnet.technic)

Links are a Pitsco-Dacta item, but I don't know if they ship to Australia. They are really useful for solving tricky problems, and having two different types is handy. They are expensive, however. Sometimes I use them where I need a little more (...) (25 years ago, 4-Dec-00, to lugnet.technic)

I came up with a Lego implementation of a clock striking device that strikes a bell to indicate the hour. At 1:00, it rings the bell once, at 2:00 it rings the bell twice, etc. It is powered by a weight, and it will play the sequence of hours over (...) (25 years ago, 4-Dec-00, to lugnet.technic)
