  1. The URL is: http://www.rmweb.co.uk/forum/ but it hasn't been working properly since the last forum software upgrade: Martin.
  2. Hi Gordon, Call 'em what you like, but... https://en.wikipedia.org/wiki/Busbar Martin.
  3. Hi Gordon, Buss was wrong. It should always have been bus bars, or correctly 'bus bars, or strictly omnibus bars. omnibus is Latin, meaning "for all". It is the same meaning for common electrical connections, and for public transport to town, and for other things. It is also sometimes used to mean several items combined into one, such as the omnibus edition of The Archers at weekends. (Does that still exist?) cheers, Martin.
  4. Hi William, That's not directly supported, but it is not difficult to do if needed: 1. set the required flare length and/or end-gap, and a machined end. 2. wait until the track design is finalised, as with shoving timbers, etc., otherwise you may need to do it all over again. 3. split out the machined end of the wing or check rail as a separate partial template. 4. set peg free, and then move the peg manually to the start of the flare (CTRL+F8 or 8 mouse action). 5. rotate the end of the rail around the peg as required (F8 mouse action) and/or adjust the end-gap at the same time, like this: 6. store it, and ideally add a prefix tag so that you can easily group the two templates later if needed. When you get into Templot at this level, it is better to swap to the Templot Club forum, rather than RMweb. For example my previous comments about adjusting the wing and check rails were covered in greater detail in this topic: http://85a.co.uk/forum/view_topic.php?id=2555&forum_id=1&jump_to=17633#p17590 cheers, Martin.
  5. Hi William, A few adjustments are still needed. Your wing rail at A is too long and does not leave a clearance for wheel flanges on the adjacent running rail. You need to shorten it to a minimum, like this: (To shorten a rail to a minimum, you must first shorten the flare length to a minimum.) It will continue to work fine as a wing rail provided the unflared portion (in yellow) reaches at least beyond the nose of the vee. A practical minimum is to have it reach at least the centre-line of the timber supporting the nose of the vee. Also, your check rail at B is too short. Wheels arriving at B from the right must be under the control of the unflared portion of the check rail (in yellow) before the opposite wheel reaches the knuckle bend in the wing rail. You need to lengthen it as above. Here's a prototype pic from the Scalefour Soc showing a wing rail machined to clear the adjacent running rail: © linked from: https://www.scalefour.org/resources/trackdetail/chairs04.jpg cheers, Martin.
  6. Hi Mike, Just a reminder that an XtrackCAD track plan can be exported as a DXF file and then imported into Templot's background shapes. This gives you a guide to work over in Templot which will be the correct size automatically, unlike a screenshot or printout from XTrackCAD which would need adjusting to size, and go fuzzy when zoomed. More info about importing DXFs from XTrackCAD here: http://85a.co.uk/forum/view_topic.php?id=3049&forum_id=1 cheers, Martin.
  7. It's noticeable that we are all seeing the same bugs in the brain code. You would think the brain programmers would have fixed them, after all these millions of years.
  8. Who, what, where is this line in the landscape? (tree bottom right) linked from: http://img.radioparadise.com/slideshow/720/54283.jpg Martin.
  9. If you use one of the custom activity streams (or create a new one of your own), clicking the topic title is then the same as clicking the star or bullet, it goes to the first unread post in the topic: I don't know why custom streams should work differently from the default streams, but Invision software is never very logical. Martin.
  10. Hi Keith, From your photos it seems the map is wrong, showing the tram track central between the roads under Five Ways. Your photos appear to show 2 tram tracks on the north side, with road traffic on the south side, unless I'm missing something? On the other hand the tram track is shown on the south side along Hagley Road? Is that both tracks, or one each side of Hagley Road? There is a lot more space for a tram stop on the south side of Hagley Road, so why use the north side in the underpass? p.s. it's OpenStreetMap. If it's wrong we can fix it.

  11. Here's a slippy map showing the route under construction from Centenary Square to Five Ways (orange line): https://www.openstreetmap.org/way/477691478#map=17/52.47650/-1.91023 p.s. It's OpenStreetMap. That means if you see something wrong on the map, you can fix it yourself. To sign up and get started, go to: https://www.openstreetmap.org/user/new
  12. If the spelling is correct, right-click on the word, and then Add to dictionary. Martin.
  13. Hi Andy, See: https://www.rmweb.co.uk/community/index.php?/topic/150352-expandedcondensed-not-working-anymore-for-me/ Martin.
  14. Hi Ron, When that happens, there is a clickable option below it, to convert it back to a link only: cheers, Martin.
  15. I never refer back to anything whatsoever unless the poster has the sense to post a LINK. Clicking I can do. Hold down the Ctrl key, and one click. The referenced item opens (eventually -- this is RMweb after all) in a new browser tab. You can go on reading in the existing tab until it appears. After looking at it, you can close that tab. No scrolling, no hunting up and down, no jumping back to previous pages, no losing your place. It seems a no-brainer to me -- always post a LINK if you want someone to refer to somewhere else. cheers, Martin.
  16. Hi Andy, Have you given up on Proto87? Also there are several narrow-gauge options using 16.5mm gauge -- in 7mm/ft, 10mm/ft, 1:45, 1:64, 1:32 scales. The better versions of those use a wheel profile matching the scale, which often means handbuilt pointwork. p.s. millimetre is spelled like that. cheers, Martin.
  17. Hi David, Only Terry Flynn at AMRA can answer that. He always refers to it as H0-SF at 16.25mm gauge/1.05mm flangeway (as shown in Templot for H0-SF). The difference between the 2 pages is a mystery to me, since "check gauge" is mostly relevant to crossings. Either way it is 15.2mm MIN, which is the critical dimension. When I asked him about the gauge difference, his reply was that it related to the manufacture of the track gauges, in that there is no 3-point gauge available. cheers, Martin.
  18. To answer that you need to know 2 things: 1. whether you claimed to be complying with a standard, and in which case, 2. which standard you are referring to. The OP is in Australia, so if we are going to break a standard, this one seems to be the one to have a go at: https://amra.asn.au/wp-content/uploads/sites/7/2016/03/finewheeltrack.pdf From which for H0 (correctly shown as such, not HO): page 2: Flange thickness 0.7mm MAX -- same as Romford/Markits wheels Back-to-back 14.5mm MAX -- same as 00-SF for Romford/Markits wheels page 5: check gauge: 15.2mm MIN -- same as 00-SF track gauge: 16.2mm MIN -- same as 00-SF Martin.
  19. Many thanks for reminding me of my web page at: http://4-sf.uk/history.htm I have repeated myself so often over the years that I have forgotten what I wrote where. I prepared a long reply overnight basically repeating all that, but it got lost when RMweb crashed. I think in future I shall just keep posting that link in reply to these topics. Over and over again. I doubt many will actually read it. cheers, Martin.
  20. Hi Andy, You don't find those words applying when 00-SF is used with its original intended kit wheels set to EM minus 2.0mm. For those wheels it is just as much a "Real" standard as EM. But those words do apply -- IF, IF, IF (how many times do I have to explain this?) you ALSO want to use RTR wheels on 00-SF. Unlike NMRA modellers in your part of the world, many 00 modellers in the UK do want to mix kit wheels with RTR models on the same track. 00-SF has been "found" to allow that with "most" "modern" RTR models, without causing wheel drop for the kit wheels. I don't think it is unreasonable to make that fact known - for modellers who are prepared to take a bit of trouble checking the back-to-backs of their RTR models. Many modellers who have tried it have been well-pleased with the results. The narrower flangeways also look much better than regular 00. • Currently Peco pointwork has exactly the same check gauge as 00-SF at 15.2mm. (1.3mm flangeways on 16.5mm gauge). Ideally therefore RTR back-to-backs should be set to 14.4mm MAX, to run smoothly on Peco pointwork. That just happens to be exactly the same as 00-SF for RTR wheels. Martin.
  21. The actual claim (if you want to call it that, I would call it simply a report) is: "Most modern RTR models will be found to run fine on 00-SF straight from the box. But there is always the possibility that you will get a rogue wheel set which needs adjusting." Note the words most (not all) and modern (not stuff you have had for years). I tell folks that they should not use Templot if they are not prepared to read the words. I think I shall start doing the same for 00-SF. Martin.
  22. Hi CK, You didn't mention the type of wheels. The back-to-back limits for 00-SF are: RTR wheels: 14.3mm MIN, 14.4mm MAX. Romford/Markits wheels: 14.3mm MIN, 14.5mm MAX. Kit wheels such as Ultrascale: 14.3mm MIN, 14.6mm MAX. If you use wheels with back-to-backs outside this range, they won't work reliably on 00-SF, as you found. 00-SF was not designed for such an odd assortment of RTR wheels. In fact it wasn't originally designed for RTR wheels at all. It was designed back in the 1970s for kit wheels such as Romford and Ultrascale. It has been found that most modern RTR does run on it quite well. But unless you have a need to run kit wheels at the same time it would probably be better to stick to ordinary 00 if you have a wide assortment of RTR models. cheers, Martin.
  23. But he was asking for advice from 4mm scale modellers using 16.2mm gauge: "I know that are some 4mm scale users doing similar, any issues when using NMRA (110 mainly) wheels properly gauged?" I answered that specific question -- 00 RTR in the UK mostly uses RP25/110 profile wheels, and "properly gauged" means 14.4mm max back-to-back for use in the UK on 00-SF. Martin.
