(...) I'm eager for mine to arrive, too! I think the axle fitting is important. If you want to add coupling rods between wheels, you MUST have opposite wheels turning together on an axle, you MUST have at least two pairs of wheels like this, and you (...) (21 years ago, 16-Dec-03, to lugnet.trains)

(...) Has anyone worked out how to get the push rods to work perfectly ?? On these combo's ,4 4 0 , 4 6 2 , etc ?? I've had a look ,at a real steam train, at a local park. And I found that the push rods are in the same position, on both sides. But (...) (21 years ago, 20-Dec-03, to lugnet.trains)

(...) I suggest that you look again as that's counter to my experience, every steamer I have ever seen has the rods quartered. Is this a static model that maybe was disassembled and incorrectly reassembled? Or are you being fooled by something else? (...) (21 years ago, 20-Dec-03, to lugnet.trains)

(...) Think of it as a physics problem, since that is what it is. If the two connecting rods (one each side) are at 180 or 0 to each other, then when one is at a end, the other is at end as well. When you push on one or the other of them, nothing (...) (21 years ago, 22-Dec-03, to lugnet.trains)

(...) My 'Challenger' model is a 4-6-6-4, using Ben's wheels in two sets of "6". You have to de-flange the middle wheels in each set in order to allow them to slide inside and outside the rails around the corners. If you try to keep the flanges on (...) (21 years ago, 22-Dec-03, to lugnet.trains)
