 | | Universal Joint Modifications for Train Applications —Mark Bellis
|
| | | Has anyone modified a universal joint? Was your modified part successful? I find that the uni joints are too long for certain train applications. I propose to take a broken uni joint (the axle holding parts break at the ends), and do the following (...) (21 years ago, 4-May-04, to lugnet.technic, lugnet.trains)

I even tried a sliding joint with square tubing, with some success. But I never got around the length of the (...) (21 years ago, 6-May-04, to lugnet.technic)

| | | | (...) 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 (...) (21 years ago, 7-May-04, to lugnet.technic, FTX)

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.

The bogie centres are still 1ft too far apart at 26ft (26L), but I have 1.5L of axle in the middle, giving 2 lots of 0.5L support from liftarms and 0.5L in the middle for (...)
