Take a look at Leo Dorst's LEGO clock: http://carol.wins.uva.nl/~leo/lego/clock.html You only need the pendulum, escapement and cogwheel part. The idea would be to use the weight of the base to drive the escapement and a pendulum to make sure the escapement turns at a constant speed. As an added bonus, you would get the "tick-tock" sounds as the base sinks. This would be very cool! I'm almost tempted to make something like this myself. Fredrik

		Re: Any ideas on how to do this with Technic?
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, (...) (25 years ago, 30-Nov-99, to lugnet.technic, lugnet.adventurers)

		Any ideas on how to do this with Technic?
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 (...) (25 years ago, 30-Nov-99, to lugnet.technic, lugnet.adventurers)
