Silver Lady (question)

I know someone out the there has one of these, can you tell me, with the sprung chassis is the centre axle still blind (flangeless)?
 
That was exactly where I was going Tony, thanks. A simple change of axle set. That will of course slightly restrict it's turning radius but not enough to bother me with 4ft min.

Hmmm! Now where can I acquire some pecuniary assets? :devil::giggle::giggle:

Just out of curiosity - why would you want flanges on the center drivers?

The wheels on the blind axle are actually smaller diameter so don't touch the railhead, meaning that effectively it is only a four wheel loco.

Tony, do you have experience with a six wheel convert? as long as there is a bit of axle end-float I'd have thought it would manage reasonable radius'.

I fact another option could be to turn the flange off a standard wheel so still get the drive from it while blind. it was done on full size.

Still a relatively cheap experiment once you have the loco.

Yes, I have a Lady Anne with 6 flanged wheels. End float is the answer and I achieved this by filing a small amount of the centre axle's bearing thrust faces, so allowing the centre axle to float by a small amount from side-to-side. I have 4ft 6in radius points on my line and they do not present a problem, but I have nothing of smaller radius to try it on.

That's not true - As you said - the Silver Lady has suspension and - just like my Roundhouse Atlantic - the flangeless center drivers have the same tread diameter and therefore the same axle loading and traction capability as the flanged drivers.

That's the whole point of having suspension on models of this size - so all the wheels stay in contact with the rail, with the consequent smoother running and better cornering capability.

I assumed, not always a good idea, as both my Countess (Accu I know) and my L&M have smaller wheels. It seems to be common practice.

Thanks for that info, as that probably means hat the extra flanges may not be needed. after all.

Well, I just measured the wheels on my L&M - and both flanged and flangeless ones are all the same at 41.89 mm over the tread diameter.

I never realised how important suspension was in locos of this size untill I compared my Atlantic and L&M together on the same track. In spite of being shorter and lighter - and not having the benefit of a leading truck - the Atlantic is a far superior runner and I would imagine the Silver Lady is too.

I used to think that flanged wheels looked better than blind ones - but when you see them on such iconic full sized locos as the 9F's and the P2's - they don't look so bad .... :)
 
Hmmm! Interesting! My L&M is 42.24 on the flanged (tapered treads) and 42.09 on the (parallel treaded) blind. I can't match your 41.89 at all????? (Digi. vernier) My L&M is one of the last batch.

I think you will find that the P2 being a 2-8-2 had all wheels flanged it was only the 9F that didn't, I am not sure but I think the WD Austerity 2-10-0 also had all flanged wheels as it was restricted to where it was allowed to run.
