| (...) There are pictures of Shays at: (URL) #6 is the one I'm building a model of, as its wheels are bigger than on most others (4ft rather than 3ft), so the BBB wheels (3'9" in 8mm:1ft scale) fit better. So far I cut up 6 5L axles into 3.5L and (...) (20 years ago, 8-May-04, to lugnet.technic, FTX)

| (...) For what I can read, it seems to be a good use for the broken u-joints (yes, they are toooooooo long)... but, can we see the piece modified? It may help looking for an alternative solution. An also, where can I see a Shay engine? I've never (...) (20 years ago, 7-May-04, to lugnet.technic, FTX)

I imagine the body truss made of long side rails, that the hips connected to. When I started (...) (20 years ago, 8-May-04, to lugnet.technic)

(...) leg_cost = 2 pistons, 4 switches n_legs = 8 legs_cost = 8(2 pistons, 4 switches) = 16 pistons, 32 switches timing_cost = 2 pistons, 2 switches reverse_cost = 8 switches turn_cost = 8 switches total_cost = legs_cost + (...)

If we measure the total distance front to back that the foot travels, this tells us the (...) (20 years ago, 8-May-04, to lugnet.technic)

| (...) All along, I'd thought that it would zig/zag as it walks sideways, as you've noted. But I was wrong. A, D, E and H are in one leg group. This means that A, and E are walking forward/left, and D and H are walking backard/left. This means that (...) (20 years ago, 8-May-04, to lugnet.technic)

| (...) Michael, From your brief description, it sounds like a dacta activity pack. You could narrow down the search for us by answering a few questions: 1) Is the box cardboard or plastic? Which logo is on the box (if any)? 2) Is the set 4.5V, 12V or (...) (20 years ago, 8-May-04, to lugnet.technic)
