(...) Well done Larry. The big boy I built accually is shorter than Dan's big boy, but it is because I scaled the real train schematics to lego grid paper and worked from there, scaling using the diameter of the driver to match the technic medium (...) (25 years ago, 23-Mar-00, to lugnet.trains)

(...) It's funny to speak of a loco that had a lifetime of what, 4 years from acceptance trials to being scrapped, as having eras (!), but I get what you mean. I'd go with whatever is easiest to model, or if it's a tossup, as built. I think there (...) (25 years ago, 23-Mar-00, to lugnet.trains)

(...) Here is a question for someone to give some thought to. Is there a way to get a third wheel between to two wheels on the 9v train motor. (of course I am talking about one side of the motor, but I would do it to both sides...) There is a hole (...) (25 years ago, 23-Mar-00, to lugnet.trains)

(...) I have seen people put the 12V center wheel from a 12V motor there. Not sure how they did it. If you do, you lose the outer cladding (which simulates the truck sideframe members, spring hangers and other stuff). (25 years ago, 24-Mar-00, to lugnet.trains)

The central wheel from the 12V train motors comes off by simply pushing it upward, yo then fit the wider hub into the top of the hole in the middle of the 9V motor, and push it down. It allows a 6 wheel setup. They don't exactly match, but if it is (...) (25 years ago, 24-Mar-00, to lugnet.trains)

Thanks for the advise Michel, After looking over the Jawn Henry schematics last night I noticed that each six driver wheelset, there being 4 sets of 6, has an offset between the first and second pair of drivers, then the second and third are close (...) (25 years ago, 26-Mar-00, to lugnet.trains)

Lar, When I read your comment I jumped up to check it out. The center slider[1] evolved from an unattached wheelset, which is why it had to be in the center. When you said end slider I thought, "Power for my SD40!" I did not try to make it, but (...) (25 years ago, 27-Mar-00, to lugnet.trains)

Wow! Thank for the construction tips! I guess I may be one step ahead then. My Big Boy's tender operates on an end slider of two attached wheelsets. I have noticed a slight uplift going in and coming out of curves, but nothing major. I guess the (...) (25 years ago, 27-Mar-00, to lugnet.trains)
