Can you please tell me whether any of the steam O gauge locos use continuous (or contiguous) springy beam to spring and equalise the axles? as popular in Scalefour? I am reading Eddie Cooke's articles and he is using individual springs below axleboxes as per LBSC practice, but... it would be nice to avoid it for protoypes which use laminated leaf springs. With CSB one could have dummy leaf springs for scale fidelity and hidden/concealed beam providing both equalisation and springing?
Many of these locos use the Eddie Cooke approach of a coil spring below the axle box - it works well but is unsightly. Yes a dummy leaf spring can be used to hide the coil. Springs / beams acting on top of the axle box is also possible. From a practical point of view, the coil spring below the axle box is easier to adjust. For maximum adhesion you want to get even weight on all the drivers.
I'm afraid there is very little newly produced O gauge live steam available. You can find Bowman and Bassett Lowke (including reproduction Corgi) on well known online auction sites.
There are two things from memory with I know Rafe included in his experimental homage to Clarry Edwards - use of ball bearings even for the connecting rods and also two pressure gauges - one for the steam chest pressure. As you see it is very powerful engine.
Checking with Rafe last night, here are some more interesting features of C R Edwards. A co-axial superheater and feed water heater, double check valves and an air vessel to smooth out the pump output. The pump is 3/16'' bore x 5/32''stroke. The double chimney has extra long petticoat pipes to try and get better gas mixture and ejection and there are working cylinder drains. Additionally, the blower and lubricator steam valves are 14BA!!
i once went to Guildex years ago and this was running on the test track, i had a chat with him and it was inspired by the work of Portas and Wardale as well as the 5AT project
istg, Live Steam models are always gonna be the coolest form of model railroading
I agree - there is tremendous pleasure raising steam and see / hear them run.

Thank you,
for my first loco I guess I beeter keep it simple :-)
and follow established (proven) practice...
@@bambukouk I like the KISS principle - Keep It SImple. At least until you've got a working engine. Then work on refining it.
Nice. Are there any kits/parts available for o scale live steam? I live in the us and i cant find anything. Most of it is g scale or narrow gauge o.

I don't suppose you could tell us a bit more about "C R Edwards", as someone with a soft spot for freelance modelling I'm absolutely smitten with it!

Beautiful
Great! 👏😊
Cool! Stéph.
