On the Kocke Klub, jan295 posted his Lego Technic "Krog" machine, and wrote in this English translation: "It works on [two Lego Power Functions Medium Motors, each driven by a "circle", and one upside down caterpillar. Drive is transmitted through the larger of the wheels (ie wheels from the set position 8292 [Cherry Picker] ); Hailfire Droid-like wheels are there to support that the caterpillar does not "sit".

"Before I put smaller wheels, the vehicle [ran] only a short time, but then eventually started a caterpillar to sit and rest it [upside-down]. Now the [Hailfire Droid-like] rings are strong enough to hold it upright....Spins [are] very fast due to the small distance between the wheels.

"The thing that I noticed in [creating loops] is that there are two types of "knuckles" on [the Lego Technic Treads]. It is therefore necessary to ensure that all loops are identical. At Bricklink, the piece marked with the same [part] number....The difference is as such [pictured below]." There are 22 BIG pictures of the "Krog" on jan295's Brickshelf gallery.

Am I blind?

I can't seem to see the actual hailfire droid wheels on this *anywhere*!

I have a set myself - scored cheap off ebay.. been meaning to build something with them, one day...

Actually, he wrote, that wheel's from Cherry Picker are there for propulsion, and smaller one's are there, to support the chain links, so the links don't ''sit down''.

Oops! :blush: I changed the original post to say "Hailfire Droid-TYPE" wheels. In the original Kocke Klub post, does anybody know what "majnša" means? The English translation software could not handle that Slovenian word....

The differences in knuckles can be used to advantage:

Oval

Square

Double loop

Running on any of these would be easiest with a sprocket and a pinch roller opposite each other.

The first two, and single loop derivatives, would make some quite interesting tracked vehicles.

"majnša" would actually had to be ''manjša'', so that means ''smaller'', .... smaller wheels .....
