Hi all!
In the past we have collected some demands we train heads have on driver
wheels. These have been requested several times at TLC so far.
Here comes the wishlist to make up a draft for a new driver wheel:

One question, I can’t really tell from the images:
Is the distance between the axle hole and the peg hole a standard stud
distance?
|
Good question! It “arguably” doesn’t matter as much as some distances though,
unless you plan to mount something between them. In many applications you
just have the main rod and or connecting rod to deal with and the
eccentricity they have is only a factor in considering how much connecting
rod and piston rod throw you’re going to have to deal with.
Still it would be nice to know. Personally I hope it’s rather short.

Well, I know how pointless it would be to “argue” with Lar (grin), but it
would seem silly to not have this be a standard distance. I could easily
imagine using a Technic cam or 1x3 liftarm on a wheel. (John frantically
searching for FTX reference for displaying LDraw images and not finding it...)
