OO v P4 Fittings for Diagram 22 and Diagram 46 Wagons

Post by theparley »

The Diagram 22 and Diagram 46 Wagons can be supplied with OO or P4 fittings. What is the difference and are both suitable for modelling in OO ?

The P4 fittings require etched W-irons and pinpoint bearings, as the spring/axlebox casting is separate. This allows rocking or sprung suspension, which is built into the w-iron assembly. The etched w-irons look better than the full casting. The etchings accommodate any 4mm scale wheel standard, provided the wheels are mounted on 26mm pin-point axles.

Just one further point, Douglas. There is really no need to go the etched w-iron route in OO or EM when you're building short wheelbase wagons. You can even get away without compensating them in P4 if you leave a little end play in the axle journals and your track is well laid. Etched components do have one advantage that I haven't mentioned. It's far easier to get the vehicle level and square on the track - castings tend to have inconsistent locations for the axles.

Mike,

I have a glass plate ready and waiting. Despite the strong recommendation by Iain Rice, compensation can wait until another day.

Thanks to Douglas for his original question. My answers have raised a point about our advertising for TL models. I think that we should scrap the 00/P4 distinction and say rigid or sprung/compensated instead.

Mike,

An alternative distinction might be:

When ordering, please specify whether you intend to construct the wagon,
(1) with etched W-Irons (rigid or compensated) or,
(2) without etched W-Irons.
We will then supply metal fittings to suit

Sounds good to me Douglas. What do Jim P and Tony think?

I sent an email to Tony, Jim Mac and Mike re sales at SECC earlier today, including almost identical thoughts on designation of castings, in light of my experiences at Glasgow
