Someone posted a great crane/construction town&technic MOC about year ago (could me more)... but I can't find it it neither of the newgroups. Anyone remember it and know where I can find the pics?

(...) snip... (...) snip... Not to be a stickler, but gearing doesn't increase motor power. Unless the large motor has less internal power loss (reduced friction would be nice) it will have more torque, less speed, and the same power as the NXT (...) (18 years ago, 14-Mar-07, to lugnet.technic)

Timothy is right about the mechanical advantage, and explained it very well! One more thing to remember is that since the worm gear acts as a "lock" for the other gear, you don't want to put too much torque on the other gear. You can either rip the (...) (18 years ago, 14-Mar-07, to lugnet.technic)

(...) Basically, a worm gear has one tooth. So using that with a 40-tooth gear reduces the rotational speed by a factor of 40, and increases the strength by the same amount. Also, worm gears can drive a gear, but can't be driven by that gear, so (...) (18 years ago, 14-Mar-07, to lugnet.technic)

This may sound stupid, but after half a decade of not playing with my Legos, I have forgotten some basic stuff, which I was wondering maybe you could help me with. My biggest is with gears. Can someone explain to me why using a worm gear with two (...) (18 years ago, 13-Mar-07, to lugnet.technic)

Hallo Eric Thanks for your interesting in my crane. I did offset the weels from the hubs, because the pivoting-point come closer to the middle from the wheel, so it needs not to much space for the wheels, when they are steered. Beat (18 years ago, 13-Mar-07, to lugnet.technic, lugnet.modelteam)

Hey coolness, I like the way you built that. Also, having grown up in the Bay Area, I can't tell you how many times I have been across the Bay Bridge! So, it is all the more fun to see, thank you! -Eric (18 years ago, 12-Mar-07, to lugnet.trains, lugnet.technic)
