About a year and a half ago I became obsessed with the desire to build a
functional mechanical clock out of legos. Somehow I was able to get my
friend Scott cought up in the madness. After 2 previous versions and many
frustrations and a few months off inbetween we finally have something to
show for the countless hours of play:Approximitly 28 hours of runtime with a
2 second period pendulem.Unfortunatly lego does not sell individual parts so
large projects get expensive,Because of this I've been forced for the time
being to settle on a wall clock opposed to a Grandfather Clock.For ease of
monting and future access my clock is built ito two main parts.
The clock itself is the first part and it is regulated by a pallet and a
84 toothed escapement(2 42 tooth lego gears from the 1970's gear set 001,the
pallets are built with 2 1x2 tripple slopes)which is synchronized threw a
quickrelease to a second hand.The second hand then drives the rest of the
clock.The quick release enables the clock to be set.The clock also has a
cogwheel that allows the wench to be wound.
The second part mounts to the wall via drywall skrews into a stud.This
part contains a 5 pully block and tackle and winch conected to the drive
weight(non lego string and weight)the winder for the clock(I seperated the 2
parts of a 56 toothed technic turntable for this purpose)and a contraption
that lays the string back and forth on the winch during winding, the
pendulem also stays on the wall.
As soon as I figure out how to build a lugnet page I'll go into greator
detail and post quality pictures and a movie.For now you can go to

If anyone is interested I plan on makeing a .dat file

| Always interesting to see a new clock. Cool. I just purchased some of those big old gears with the thought that the larger teeth might make them useful as an escapement wheel (they're in the mail from the ebay seller right now, hopefully!). I'd love (...) (23 years ago, 8-Dec-01, to lugnet.technic)
