Well, no, in fact.......................................The real thing has the axlebox moving with the axle. Your version is prototypical as is and congratulations for making it work.
Oohh, I thought the axlebox was fixed to the W-Iron and something moved inside like we do with Bill's units. Ok cool. Thankyou.

Hitchhikers Guide to the Galaxy I recognise, but sadly I don't get the message.
No you are not the first -- there are even etchings available at least in 7mm, and the guy who designed them has some idea of the physics involved.
Horsetan also pointed me on RMweb to possible the first one to try it also. I've quoted it below for everyones benefit. I don't think he'll mind as he is on here too.
He mentioned it in MRJ no.6, I think, when discussing his methods of sprung suspension. That was back in 1986, and he had many of his engines running on rubber pad blocks. Subsequently he adopted individual single-wire leaf springs for his Peppercorn A1 (MRJ 28 and 29)
EDIT: I don't think Chris Pendlenton carried on with his celluloid experiments on wagons, though. If you read his later articles in MRJ, e.g. the one on mineral leading (MRJ 173, I think) you'll see that he uses the single-wire leaf method.
Weight's important, though, and your individual phos. bronze leaves would probably work better under a whitemetal or etched brass vehicle.
What's the best way to obtain old issues? I'd like to read those ones.
Where can we see the video of them 'working'?
I have thought of making a video and might do. I'd feel better making a video of a second more refined version on another wagon. As is evident by the pictures the prototype attempt is a bit rough and ready to say the least. I'll be doing a second wagon though at some point as I'm determined to get a polished consistant example. Once I'm fully happy I think it's safe to say I'll do a video. My somewhat n00by track will prove a good example.
Our hobby needs people willing to think outside the box if it is to continue to develop.
Indeed, most boxes are self made retarders for the mind. I guess that's why they call it a box. A trap of sorts. (Umbrella: I'm not saying people are retarded for not looking out of a box, don't get the wrong impression!)
To get effective working springs you may need to have some of them dummy with just the top one actually doing the suspension (the scale effect thingy).
Based on nothing more than the experience of this one wagon, I disagree (currently). I did fix some springs together meaning they hardly flexed and so just the top one worked, but this limited the operation considerably. The best springs out of the 4 ends are the ones where they are mostly loose and all free. The top biggest spring does a lot of the work being the first to recieve weight and being the longest thus weakest, but when flex testing it clearely isn't the only one doing the work. Free movement seems to prove a softer flex.
If people can make working inside valve gear in 4mm scale, there was a beautiful example to be seen at Aylesbury for example ) then I don't see why working wagon springs can't be created for those that want even more realism.
I've never tried working inside valve gear and unsure if I'd bother, neither have I had the pleasure of seeing a model in motion that does, but like working wagon brake gear (that Ted Scannel has done and I want to some day), these springs and modelling the inside of a building your never going to see, I guess it's the personal satisfaction you get from things. For me, all this type stuff is also added play value. I sometimes like to pick one of my wagons up and play with the springs and sprung buffers. Why? erm, maybe I'm mad, I dunno.
Knuckles, I have just spent a thoroughly interesting morning reading your posts. What an inspiration. I have just returned to modelling after a 20 something year break and find that it is as if I had never done anything before. I am impatient to get on but, when you have to start from scratch, building track and wagons etc., it is difficult to know where to start. Your posts have given me the enthusiasm to plough on and learn again as I go. Many thanks. I suppose that I may even have another go at the brass wagon that was going so well until I held the soldering iron on it for a second too long. Now where are all those component parts?
Thanks Tony, that's really great to hear, glad I could help. Thanks for the kind words. This is partly why I continue to do these bloggy posts, I've had loads of messages similar throughout doing these documentation things since about 2006-ish.
Oky doky. Thanks for the replies everyone. I'll continue with this experimentation in due time.
I've replied to a few comments that were not aimed at me but just wanted to discuss things. Out of all the railway modelling forums or areas in a non modelling forum I'm a member of (4) , our S4 one easily tops them all. I'm not on about just this thread but everywhere.
