... to be displayed and the hidden half of the of the same quarter diamond that has been cropped using F4 to do this. Below, is a much more detailed explanation: You see, each of the quarter diamonds is made up of a rear half (the vee and wing rail end), which has been cropped by using CNTRL+ F3 blanking length, and a front half (the K crossing end), which has been cropped by using F4 overall length. Now angle adjustments have to be made between the two halves using F5 size, so that the rear end gives the correct flange gap between the wing rail and the vee, this has the effect of not allowing the front end to meet at the centre of the crossing curves, so I had to crop off the front end as far back up to the check rail front tips. Now to make the second half front (K end) align to the centre crossing lines of the two curves, I used F5 size again to make the alignment, and then used F4 overall ...
... . That the problem recurs after variable time span suggests that the card may be overheating. The fact that you have the Camtasia video player running at the same time may be contributing to this. Does the problem occur when using Templot without the video? What happens if you change your system to a lower colour quality/depth? In Templot there is no advantage in using true 32-bit colour, results are just as good in 16-bit (medium quality) colour, and the load on your graphics card is halved. When this problem occurs, what happens if you launch some other application, say Windows Notepad, and drag its window around over the Templot workpad? What happens if you minimize Templot and then maximize it again? What happens if you simply press F12? Sorry this is all questions and no answers. regards, Martin. posted: 23 Jul 2007 17:23 from: Phil O Hi Martin "Does the problem occur when using Templot without the video?"

Regarding the four way, I may consider trying to split it, and build as normal from the front in each case, but time and mistakes will tell. Best regards. Brian. posted: 2 Sep 2010 17:33 from: Brian Nicholls Hi All, I have today started to do the timbering on the previously posted formation, however, I cannot seem to get the timbers back on the two halves of the diamond crossing, does anyone have any idea why this is? Also I would like to clear up one erroneous point I mentioned on the formation, I did make a slight TYPO when I stated that "I used a straight 1:4 diamond crossing, and I did not intend, at this stage, to get involved with trying to make a curved diamond out of partial templates". This implied that the whole diamond was straight, where in fact I did actually use partial curved templates to complete the ...

... to the control.- and lost the live template...? but it otherwise seem to work fine. I then went on to follow the next 4 lines which all worked fine as far as I could tell, namely- Move the peg along it to the intersection (CTRL+ F8).- Store and background.- Change to constant radius.- Click other template and make diamond-crossing at intersection. At this point it seemed to work too well because as far as I could see the two halves of the diamond were there just as happens with a constant radius(which of course it now is or was???). But after that I couldn't see that I needed to do any further alignment so I didn't do any of the following. Is this where I went wrong. If it was then for some reason I couldn't see that any further alignment was necessary?- Click transition template and align one half-diamond over it and snake onto peg.- Use F9 mouse action to align the V ...
... 21:48 from: Andrew Barrowman Looks like we can forget about the HP nylon material. It is quite robust but the definition is not good. The bolts/screws on the chairs are barely visible. The jaws are also quite inconsistent. I can do a lot better with my own FDM printer.

... not talking about cutting the whole base off Just cutting the chair in half down the centre will leave the part of the moulding which sits directly under the rail. Cut the chair flush against the side in the gap(where the rail sits) on both sides, it takes a second if that. Its much the same as cutting the pip off which attaches the chair to the sprue I use the round Swann Morton number 3 blade for this job, and an uneaten thumb nail and fore finger are needed to stop the halves from flying apart, or hold it down on a strip of double sided tape on the board Last edited on 2 Jun 2015 07:25 by Hayfield posted: 2 Jun 2015 15:30 from: Martin Wynne Martin Wynne wrote: I have some new Vero pins on order from RS which should be here tomorrow.

... way, the long timbers at the centre are 20ft long. The longest timbers in a single turnout were typically 15ft long, with interlaced plain sleepers beyond that. 4. timbers should not be too close together side-by-side, so that the gang can get a shovel under them to pack them with ballast to level the rails when needed. 5. likewise timbers should not be too close end-to-end. In that case either a single long timber is used instead, or two shorter timbers are halved and splice together to create a long timber. Such spliced joints have old fishplates bolted across them -- a nice modelling touch. 6. sometimes timbers must be moved from the ideal position to allow for point-rodding runs, signal wires, etc., and must sometimes be shortened at one end to clear catch pits, drains, etc. Here are a few links covering this subject on here: topic 2628 topic 2460 topic 1610 There are many more timbering topics if you do a search. regards, Martin ...
... fit the uncut part of the check chair alternatively to the stock rail then the check rail Some people will advise using standard (S1) chairs for the check rail on the basis of alternating between the stock rail and the check rail, with cosmetic 'half' chairs to fill in the gaps. However, this will have the wrong chair detail as check rail chairs are always 4 bolts. Whilst at both ends you use a selection of whole standard and bridge chairs which will hold the common crossing in place the common crossing chair halves do actually hold the crossing in place as well EDIT: See Martin's comment below. My advice is to try composite, ply and even plastic if you like and see which you get on best with. I know composite build is popular, but I think if you're going to use ply- stick with ply. Good luck. As Martin has said the best method is the one you can use, unless your plain track is ply there is no problem using the composite method and it is certainly easier to make. ...

Regards Tony. posted: 12 Oct 2016 17:11 from: FraserSmith A summer of inactivity on my planning is now past and I'm back to the computer for some more Templot trial and error.

The plan now looks like throat.png 3137_121136_060000000.png Click here for BOX file Questions 1) The diamonds are obviously quite different in angle and length and also different in their two halves. I assume it would be more prototypical to use the same angle for all of them? Would making the crossing roads away from the central crossing as curves rather than straights help? 2) I want to make the six outer ones into double slips. I have done this as shown in my efforts in my previous postings but I have been thinking about the blade sizes to use. The defined blades only go to 1:6 whereas some of the angles are coarser than that. Does it make any difference if ...
... few months I'll be able to do the 2-bolt GWR slide chairs in 4mm scale, once I am re-united with my casting machines. In the meantime the 7mm castings seem to have gone reasonably well and I have a small stock of the Heyback chairs for Flatbottom, I haven't decided on a price for these as yet and there is no photo as yet since I haven't got around to acquiring any Code 143FB. However, the crossing nose chairs are now available for purchase. Price is 50p for the 2 halves, though anybody wishing to purchase should probably think about buying a few, to save on postage. See attachment for picture. For anybody who has seen them on my website, please note new pricing and also could I just mention before anybody asks, the boltheads with square plates are from Grandt Line. I think they have also have a suitable size in 4mm (OK 3.5mm) scale. They are not something normally modelled in the UK, or at least I haven't noticed them on model trackwork here.

... . posted: 13 Feb 2017 17:00 from: Martin Wynne Hi Fraser, Crossing timbers were (are still?) generally stocked in 6in. increments up to 15ft length (for turnouts) and in 19ft-6in or 20ft length for crossovers in ordinary double-track. Longer lengths could be specially ordered by the designer up to 30ft, but they are expensive and difficult to handle, so avoided if possible. Where it is necessary to place 2 timbers end to end you have a choice. Sometimes timbers were halved and spliced together to create a very long timber, using old fishplates bolted through the joint as stiffeners. This makes an interesting seldom-modelled feature. The disadvantage is that it is a lot of on-site work to do, and the creosote protection is largely destroyed in the process, leading to early rotting. Alternatively you can simply leave a gap between them, provided there are adjacent timbers holding the rails to gauge. This means the gaps would be typically alternated in adjacent roads, and ideally placed in the ...

... how this compares with your D-9. 2_011355_290000000.png Comparing this with the standard REA bullhead turnouts in Templot, you will notice that Templot is a bit more generous with timber in places than this chart requires. This reflects the general practice in bullhead days. The design rule seems to be that timbers were available up to 15ft long for use in turnouts, and at 19ft-6in or 20ft for spanning double track in crossovers. Longer timber lengths up to 30ft could be specially ordered, or created on site by means of halving and splicing. Of course it is up to the designer to decide what lengths to use in a given case. In Templot the crossing timbers run up to the vee rail joints, with plain sleepering beyond (unless the real> timbering> exit track setting is changed). In some shorter crossings this causes the 15ft limit to be exceeded in Templot, for example a 1:5 crossing in Templot has the longest timber at 15ft-6in. To confuse the issue, this drawing of a 1:8 BH ...
... magic number derived from the circumference of the Earth at the Equator. latitude is at the centre of the map area, e.g. 52.1234 degrees pixels is the width of the image in pixels, e.g. 1280 scale is your model scale in mm/ft, e.g. 4 zoom is the zoom level of the map, e.g. typically in the range 17-21 for our purposes, where zoom=0 means a map of the entire world. Fortunately if you get zoom wrong it causes the width to double or halve for each step, so it is fairly obvious to correct. Here is how to find the information in a typical URL: maps.nls.uk/geo/explore/#zoom=18&lat=51.9959&lon=-2.1498&layers=6 &b =3 p.s. 2^zoom means 2zoom i.e. 2 raised to the power zoom regards, Martin. posted: 7 Aug 2017 03:45 from: Martin Wynne Another update.

Slimming the goods yard down a bit (prob just adjusting the fan a bit, the goods shed should have the covered track on the top side as well, so that may help) Shuffling the track at the 4' mark so the layout can be split into two halves (again, it took me hours and hours to get this from a verbatim copy to the compressed version you see here!)

... handle. No railway company is going to go to the expense of long timbers without good reason. For example there is no reason to strengthen a siding by running long timbers across under it. But running lines are different. A complex junction with heavy traffic needs to be as strong as possible to minimise maintenance. Generally long timbers can be specified from stock up to 30ft long. Beyond that in one piece gets very expensive as a special order from the timber yard. Sometimes long timbers can be created on-site by halving and splicing shorter ones end to end. The rule which can't be broken is that the special switch and crossing chairs fit the rails in fixed positions, so there must be some timber under the rails in those positions. And for robust track the timbers need to be as square-on to the running rails as possible. Where there are rail joints they need to be as close together as possible within the limits of fitting a fishplate between the chairs. That usually means 24" or 25" centres under rail joints ...
... topic: 3391 Shift and Join a Diamond Crossing posted: 5 Mar 2019 17:49 from: Murray Boaz How do I shift and join a Diamond Crossing? So far the only solution I have found is to group the two halves and move them around using the commands on the Group menu which is rather cumbersome. I have attempted a forum search without success. Help would be very much appreciated. Murray posted: 6 Mar 2019 01:58 from: Martin Wynne Hi Murray, If you have a finished diamond-crossing, then yes you need to use the group functions to move it about, and the notch-linking functions to join it to other templates. It is easy to re-create the group of two templates at any time if you use the prefix tags on the template names. However, there is seldom any need to move a finished diamond-crossing. All you need to do is move one of the half-diamonds, and then make a full diamond-crossing from it once it is in position ...
... very short (small) K angle, it is necessary to use both the above keys alternatively to get the best (if not quite correct) alignment of both the Main and Diagonal roads of the diamond crossing. I have developed my own method if I ever need a very accurate crossing match, which gets much more complicated, and you have to use multiple templates to do. It is, in general terms, done by using copied diamond templates, and using them on each of the curves for only the main road halves in each case, then removing the unwanted diagonal road parts, you then have to use additional partial templates to tidy up the K crossing area. However, I will not go any more into this method, as I do not wish to confuse you further, I think you should be able to get what you want from the usual Templot2 methods, and it's best to start with, and understand, those first. All the best, Brian. posted: 18 Feb 2014 14:10 from: Steve Bedding Following ...
... inside of curves. The contract would allow for a certain percentage of "shorts" from offcuts and where defects have been cut out. These would most likely go to the switch and crossing shop. I think it is unlikely that you would find any rail in pointwork longer than the current standard panel length. On the other side of the pond the standard rail length was 33ft, and the common American switch sizes are 11ft, 16ft-6in, 22ft -- i.e. switch rails obtained by cutting a standard rail into halves and thirds. regards, Martin. posted: 30 Mar 2012 17:02 from: ESJAYTEE Hi Howard, hopefully this will prove straight forward and its just a case of me being thick.
