New O scale Kadee trucks

[Stephen]

Oh hang on - U.S. modelling novice trap averted (just).
Proto48 is 29.9mm gauge so axles unlikely to be suitable for 32 or 33, and I guess the truck frames might be closer together too?
So maybe using the San Juan wheel discs only is the way to go.

They do produce them in O Scale as well:

#752 O Scale 2 Rail Arch Bar Metal Trucks with 33" Ribbed Back Metal Wheels

#752 O Scale 2 Rail Arch Bar Metal Trucks with 33" Ribbed Back Metal Wheels O-Scale 1 Pair Mounts with a #4-56 x 3/8 screw. or optional #770 Bolstor Adapter Sold Seperatly Introduced in the 1940’s - Used in interchange service through 1994.

Yes thanks - I'd found those (post 36) but thought the P48 wheel profile would save trimming the 0 scale ones down.
Perhaps better to consider the 752 and turn a finer profile than have another set of problems like axle width etc.
On the other hand just realised that San Juan are based in Denver, so kits could be delivered locally for onward shipping.

Seems like these cast ribbed wheels were discontinued post WW2 in favour of wrought or rolled steel wheels, and banned sometime in 70s.

Interesting description by Kadee there. Most accepted wisdom is that Arch Bar trucks were banned from Interchange service in 1939 - but Kadee talk here about these trucks being introduced in the 1940s and in use until 1994!!?? So are they really 'Arch Bar' or should they be described as something else?

Osgood, the Kadee profiles for 'normal'/'OW5' wheels are pretty fine as they are - much finer than Atlas or Intermountain.

I wouldn’t try turning the Kadee wheels, it could end in tears. Their online direct ordering is efficient so worth considering. Jordan has noticed some of the truck descriptions have been copied and pasted without being edited so a bit confused.

If the plastic San Juan wheels are good enough for you I have some spare P48 ones and I think some O scale ones you are welcome to as I will never use them. They are concentric and cast in delrin so roll ok.

The 'fluted' wheels were cast iron, & could not be fitted to new or rebuilt cars after 1958, & were banned altogether in 1970, according to this source:-

Archbar trucks - when where they outlawed?
