David the Toolman Posted September 20, 2014 Share Posted September 20, 2014 Hi All I'm intending to build a model of the West Somerset Mineral Railway at Watchet around 1920 (yes, I know it closed down over ten years earlier - artistic licence!). The rail used was flat-bottomed, scaling to code 100, and using a decidedly idiosyncratic design of chair. Two questions: anyone know a source of code 100 FB chairs? Got plenty of rail from those nice folk at Marcway, but as yet no luck with chairs. The S-scale society have been very helpful in letting me have a sample of their code 95 BH chairs, but they're too small and won't accept the track anyway. so it's either soldering to copperclad or spiking. All suggestions gratefully received. David Link to post Share on other sites More sharing options...
raymw Posted September 20, 2014 Share Posted September 20, 2014 If you solder to copperclad, you may be able to glue on cosmetic chairs at a later date. Have you a link to an image of the chair type? How many do you need? It maybe possible to get some to fabricate something that looks something like in etched brass. Link to post Share on other sites More sharing options...
Grovenor Posted September 20, 2014 Share Posted September 20, 2014 Flat bottom rail does not use "chairs", it may use "baseplates" you call them "idiosyncratic" what did these things look like? Code 100 rail in 0 gauge is a rather small size which would be mostly used by impecunious narrow gauge concerns who would often just spike the rail to sleepers, so I would think it highly unlikely anything will be available except those plastic clips used on rtr 00 track which you could perhaps slice off.

David the Toolman Posted September 20, 2014 Author Share Posted September 20, 2014 Thanks for contributions guys. I'm attaching a scan of the trackwork details from Mike Jones' epic book on the line - you'll see what I mean about the idiosyncratic rail chairs/baseplates.

Grovenor Posted September 20, 2014 Share Posted September 20, 2014 Keith, as an NG modeller who's prototype also uses Code 100 track I can tell you that 7mm Code 100 is different size-wise from 4 mm Code 100 rail Regrettably I have still to find* a suitable supply of Code 100 base plates in 7 mm scale. Have you found a supply of 7mm scal;e code 100 then? David, the OP stated he had rail from Marcway, which will be 00 code 100. (NB not 4 mm code 100 which implies it is scaled down from something!) So what would you expect the head width of a rail 4.35" high to be? The reference I have closest to hand would suggest it's close to a 60lb rail, the drawing I have shows 6 different profiles* in this range, the head width is either 2.25" or 2.375" which is between 1.3 mm and 1.4 mm in 7 mm scale. Foot width 4" in one case 4.3125 in the others, ie 2.3 - 2.5 mm. With the common code 100 being just over 1 mm head width and 2 mm foot width it is going to look skinny, especially when building crossings but it probably better than nothing. Regards Keith * 60LB ROUND TOP, 60LB FLAT TOP, 60LB BSS, 60LB RBSS, BS 60LB N, 61LB SAR Link to post Share on other sites More sharing options...
Grovenor Posted September 20, 2014 Share Posted September 20, 2014 The drawing does not enlarge well, being a very low res jpg but as best as I can tell the rail scales out roughly 4" foot width, 2" head width and 4.5" high, which fits in fairly well with the more modern steel rails above. They certainly seem to have gone to town with their chairs, but this was back in wrought iron days. Keith Link to post Share on other sites More sharing options...
RMweb Premium Mike Bellamy Posted September 20, 2014 RMweb Premium Share Posted September 20, 2014 Accurate rail is available from Karlgarin Models - several varieties are available and there is a very helpful download showing the prototype size and weight compared to their own rail and that available from Peco. All of his measurements are Imperial - height 0.099 foot 0.100 head 0.053 See here http://www.karlgarin.com/whatsnew.htm . Link to post Share on other sites More sharing options...
PatB Posted September 21, 2014 Share Posted September 21, 2014 What about the possibility of getting a batch of chairs 3D printed? Link to post Share on other sites More sharing options...
hayfield Posted September 21, 2014 Share Posted September 21, 2014 Thanks for contributions guys. I'm attaching a scan of the trackwork details from Mike Jones' epic book on the line - you'll see what I mean about the idiosyncratic rail chairs/baseplates. David Looking at your diagram, Mike and Pat's replies. It may be an answer to firstly get some rail. The 3D printed suggestion may be the best but someone needs to do the plans and what will the cost of production be? Another idea may be to adapt an existing product, could either a 4 mm or 7 mm 2 bolt chair be cut up to give a representation of the chair. Not ideal but better than none Link to post Share on other sites More sharing options...
flexible_coupling Posted September 21, 2014 Share Posted September 21, 2014 Regarding the chairs - there is a gent currently doing a lot of work on Shapeways that might possibly be in a position to assist; http://www.shapeways.com/shops/otr Never know if you never ask...

hartleymartin Posted September 21, 2014 Share Posted September 21, 2014 What you want is rather unique for flatbottom rail. You can get etched base plates, but many of us simply use thin plasticard strip if we have the plates at all! I've always spiked the rail directly to the sleepers using either "micro" sized spikes or ones made from steel office staples. Link to post Share on other sites More sharing options...
0_gauge_novice Posted September 21, 2014 Share Posted September 21, 2014 As mentioned above by Dutch_Master Wenz offers baseplates for code 100 rails. Actually he has two types for code 100 rails. His standard ones for flatbottom rail with a width at the bottom between 2-2.4mm . http://wenz-modellbau.eshop.t-online.de/epages/Store_Shop00671.sf/de_DE/?ObjectPath=/Shops/Shop00671/Products/wm0008 and the baseplattes in prussian form 6 for rail with a width at the bottom between 2.1-2.4 mm. http://wenz-modellbau.eshop.t-online.de/epages/Store_Shop00671.sf/de_DE/?ObjectPath=/Shops/Shop00671/Products/wm0148_1 You will have to spike the rails normaly with these. http://wenz-modellbau.eshop.t-online.de/epages/Store_Shop00671.sf/de_DE/?ObjectPath=/Shops/Shop00671/Products/wm0153 or these http://wenz-modellbau.eshop.t-online.de/epages/Store_Shop00671.sf/de_DE/?ObjectPath=/Shops/Shop00671/Products/WM0347 or these that are already blackened http://wenz-modellbau.eshop.t-online.de/epages/Store_Shop00671.sf/de_DE/?ObjectPath=/Shops/Shop00671/Products/WM0027 Wenz is using Code 100 from Peco so there should be now problem if you get the rails directly from the UK. I have 0m track from Wenz and it is superb although you must take your time to put it together. Cheers Andreas Link to post Share on other sites More sharing options...
Grovenor Posted September 21, 2014 Share Posted September 21, 2014 Unfortunately what David needs are not spiked baseplates, see the drawing in post #5 above. Best bet would seem to be shapeways or similar if someone can do a drawing. Keith Link to post Share on other sites More sharing options...
HSB Posted September 21, 2014 Share Posted September 21, 2014 3D printing would appear to be your best option, David. I suggest you have a chat with Chris Ward at the next EXGOG meeting. Link to post Share on other sites More sharing options...
HSB Posted September 22, 2014 Share Posted September 22, 2014 I have just looked at the KBscale site and I see they are now listing the Karlgarin Code 100/7 rail. Link to post Share on other sites More sharing options...
David the Toolman Posted September 22, 2014 Author Share Posted September 22, 2014 Thanks Howard and everyone else - we have a 3D printing expert just joined Exeter Gauge 0 group, so will sound him out as to viability. David Link to post Share on other sites More sharing options...
