Hello,
I have uploaded pictures of the oldest moc in my collection. It
is another attempt at continuous marble motion. http://www.brickshelf.com/cgi-bin/gallery.cgi?f=34275
It employs a pneumatic scissor jack that lifts a marble up to the top of a
track, then the marble falls back down to the beginning. You can also find
3 more pictures of the air compressor here: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=34286
Enjoy
Chris
