I can't see how you can have automatic gauge widening on flexi-track as what ever radius it's curved to the dimension between the chairs will all ways be the same as when its straight, the chairs wont spread apart

The "automatic" gauge widening comes from the inclined rail which becomes more vertical as it is curved i.e. the foot of the rail stays where it is but the heads get further apart. At least that's how bullhead works, not sure if flatbottom does the same thing. A bit of schoolboy trig indicates approximately 0.32mm (about ½" full size) of gauge widening if the 7mm scale rail becomes fully vertical; probably depends on how distorted the chairs can get.
If you get a different answer then you obviously asked a different schoolboy...

Gauge widening on the prototype was used on curves of radius
between 10 and 7 chains ...+1/4"
7 " 5.5 chains..+1/2"
under 5.5 chains.........+3/4"
All these must be fitted with a check rail.

Check rail required under 10 chains only if carrying passengers or vehicles "climb" over the outer rail.

I would stick to 7mm F/S if you are contemplating a garden railway

No good if all your stock is S7

So ... how much does it cost to have wheels reprofiled?

Jon

ZiderHead,
Re- profiling Slaters or similar £4.00 per wheel + p&p that includes thinning down to scale tyre and boss width if possible.
Turning cast wheels from a blank casting £25/pair.

ATB, Col.

From what Jon has posted so far, I was under the impression that he is just about to start building/ collecting stock. If this is so & he is also about to build a garden railway, then I would not use S7 as a starting point.............just my opinion as a garden railway modeler

 

[ZiderHead]

Phill is correct, my current 7mm stock is 2x half built wagons! And the extent of my committment to gauge thus far is 2 sets of FS wheels still in their bags ... I think its safe to say that my modelling is more of a marathon than a sprint

Dear Bill,

(often thought about trying to start a conversation with that phrase... infamity due to P.Eye etc.)

What Colin has written is reasonable for driving and carrying wheels where there is no suitable S7 Group product. If dealing with wheels for carriages and wagons then Slater produces appropriate wheels with S7 tyre profiles albeit those wheels have a boss to the rear face and it is that boss which sets the wheels at the B-2-B for S7 - Ah!, so the axles of S7 wheel sets are the same as the axles for FS then? Seems so...

All of which means that you can buy S7 carriage / wagon wheels from Slater and reduce the boss thickness to achieve the B-2-B for FS.

regards, Graham

Apart from the issue of building miles of track, any other reason you'd not recommend s7 in the garden?

Apart from building all that track & that is a massive issue for a garden line, if you did build it, would it survive the harsh outdoor environment ?.........Peco can & does take all the abuse year after year & still works.

TBH I just don't see much point, as a good garden railway paints a picture of a railway without going in to too much detail, I don't really think the finer standards of S7 will make any visual difference in a garden but would create lots more work........probably the difference between yet another unfinished garden line & a working railway.

Another problem I would see is that for a garden railway you need to leave off impractical details on stock, which I would have thought rather goes against the improved standards of S7

Another problem could be the social element of garden railways........most 7mm modelers are still fine scale.

I could go on but I won't.......each to their own & all that. If Jon wishes to pioneer S7 outdoors good luck to him, I will be genuinely interested in his progress.
