I've received some very good responses here. Jacob Andersen's worm gear idea is what I would do if I were to use a motor, but since gravity already provides energy for the system, a good engineering solution would not use an additional motor. Plus, (...) (26 years ago, 30-Nov-99, to lugnet.technic, lugnet.adventurers)

Paul Davidson: [ Structure sinking into the ground at constant speed ] I would see if I could do something with some worm screws (LDraw part 4716), a micro motor (LDraw part 2986), and maybe some gear racks (LDraw part 3743). The worm screws will (...) (26 years ago, 30-Nov-99, to lugnet.technic, lugnet.adventurers)

(...) You can use an pendulum clock to time the mechanism so that it sinks at a constant speed. No, I'm not kidding! Take a look at Leo Dorst's LEGO clock: (URL) only need the pendulum, escapement and cogwheel part. The idea would be to use the (...) (26 years ago, 30-Nov-99, to lugnet.technic, lugnet.adventurers)

(...) Hmm. Use a pair of pulleys, one attached to the same axle as the gear being turned against the rack. The other pulley should be attached to the same frame as the first, so they move together as the building sinks. This second pulley should (...)

(...) Well, I know you don't want to use motors....but.... :) I just picked up a 3038 "Spider Slayer" set, and the motor therein is actually quite weak - put a wheel on the axle and it spins real easy. If you built your gear mechanism then hooked (...) (26 years ago, 30-Nov-99, to lugnet.technic, lugnet.adventurers)

Hi, I'm considering an Adventurers-themed Lego project that involves a structure that, when triggered, can sink into the "ground" (as on The Mummy). My general idea is that at four locations (two on each of opposite sides), the part of the structure (...) (26 years ago, 30-Nov-99, to lugnet.technic, lugnet.adventurers)
