Very nice, but unless you’re doing some tricks I can’t see in your image, your example locomotive won’t be able to handle corners.

Forget abou running behaviour for the moment: I just wanted to have an impression about the “feeling” of these wheels. How do they look like in a LEGO® engine.

For a real model it would need blind drivers or a steering mechanism like here: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=12161

As one can easiely see: this CAD-draft is quite similar to the LGB/Playmobil wheels. Since those have been tested be me and others this decreases the risk of failure.


   You won’t be able to put three of these wheels next to each other and have them go around Lego curves. If you move the middle wheels in a half stud, I think it will work - but that adds another layer of complexity with attaching the pushrods. Also, if you want to run three wheels together, it makes a very tight threshold for the shape of the flange. You need the flange big enough and angled enough that it won’t try to climb up the outside of a curve, but it still needs to be small enough to fit through the switches.

   My suggestion would be to just mold the counterweight into it, and make just one mold. Off the top of my head, I can’t think of a time I wouldn’t want to use the counterweight...

I think I have to agree here.
  
So, when can I get a couple dozen in black? *grin*

Brad said “no”. But there are other parties than TLC. Would you (and what about the other train heads?) ignore this design, when it would be done by a third party supplier?

Leg Godt!

(...) Ben - I may have missed something. What did Brad say 'no' to? Moulding this specific part, or big drivers in general? I really like the look of this part, and everyone knows we all want drivers, but I think the spokes seem a bit thin and may (...) (21 years ago, 29-Oct-03, to lugnet.trains, FTX)
