We don't even need that. Two of John's Internal gear bricks, two carriers,
some pinions and some axels are enough for a two stage planetary set. Drive
the first stage "sun" with a pinion on a technic gear motor, connect the
output of the 1st carrier to the sun gear in the second stage, tie the
corners of the two gear bricks together with 4 axels so that thay can't
rotate, and the output of the second carrier will be torquey enough to break
things : ) I haven't run the numbers, but just eyeballing it the final gear
ratio of a two stage set with John's parts would probably be in the
neighborhood of 100:1.

PS. I'm working on the DAT files to animate this. Hopefully, It'll be up
in a day or two.

| I was thinking along the lines of the old planetary gearboxes where different gear ratios could be selected by applying a brake to the appropriate anulus.
