hayfield Posted July 11, 2016 Share Posted July 11, 2016 (edited) A lot has been written and said about building turnouts and crossings and despite many saying to the contrary, the myth that building turnouts is both difficult and expensive still exists. Whilst I will be building a P4 turnout most of the methods used can be applied to either EM or 00 gauges Buying kits can be expensive, however by buying the components separately reduces the cost dramatically. Other than a few gauges ( these need not be expensive) most will have the basic tools required Yon can just start off with a simple plan, some timbers and 2 basic chair types, I will also be using a few additional chair types just to add extra detail In addition to a soldering iron, these are the basic tools surrounding various gauges The gauges from left to right 1) a set of inexpensive Exactoscale standard gauges, they also do a set for gauge widening 2) two standard roller gauges 3) two check rail gauges 4) 3 point gauge Not in the photo should be a wing rail gauge which is a simple flat bar. Most of these are reasonable in price, but with a digital calliper and a piece of scrap metal you could make your own Edited July 18, 2016 by hayfield 7 Link to post Share on other sites More sharing options...
hayfield Posted July 11, 2016 Author Share Posted July 11, 2016 The first thing to do is make the Vee, those with deep pockets and buy them skip this part, though they are very simple to file up and cost pence in materials I make a simple jig with 2 pieces of ali on a board at the correct angle(see at the bottom) and file both pieces of rail to the correct angle, then using the jig solder together Those with even deeper pockets and buy the common crossings skip this page altogether I have soldered 2 pieces of 0.5 mm copperclad (shim will do) to the Vee and made up roughs of the wing/closer rail Using a wing rail jig (a flat bar) solder the first wing/closer rail to the vee and add another piece of copperclad/shim where the knuckle sleeper is Solder the second wing/closer rail in place Cut off the surplus copperclad/shim flush to the rail sides Reverse of the common crossing showing the finished unit This is my simple jig, ali strip from B&Q, one piece screwed at both ends, the other at the fulcrum. Just cut a wedge of card to the correct angle, slide in place and tighten the screw. Acts as both a filing and soldering jig, simple to make and costs pennies 1 Link to post Share on other sites More sharing options...
hayfield Posted July 11, 2016 Author Share Posted July 11, 2016 (edited) A slight digression from the build, but this may be a simpler way to build a common crossing for the inexperienced builder. I soldered the Vee in place, then each stock rail before fitting the wing/closer rails Simply replace 3 plastic sleepers with copperclad ones Solder the Vee then each wing/closer rail to the sleepers using either thin copperclad strip or shim to lift the rail off the sleeper (so chairs can be fitted and the timbers stay level with the plastic ones Then grind the surplus copperclad strip/shim level with the rail sides so chairs can be stuck to the sides Edited July 11, 2016 by hayfield 1 Link to post Share on other sites More sharing options...
hayfield Posted July 11, 2016 Author Share Posted July 11, 2016 Part 4 Timbers (sleepers) To my mind ply timbers and sleepers do look best (and much cheaper) but plastic timbers offer the most strength. My preferred timbers are the Exactoscale timbers, they are 1.6 mm thick like the C&L thick ones and do not curl up as the thin C&L timbers tend to when the solvent dries. In addition the longer timbers are much longer than C&L ones and you get more, so you can make about 2.5 turnouts per pack For some reason the shortest timbers are 36 mm so even in EM and P4 you have to cut 34 mm ones from longer length I stick a plan to a small building board, then stick a piece of tracing paper over the plan ] I have some double sided tape, I cut 3" strips then cut them into 3 mm strips length ways and put them both sides of the turnouts to hold the timbers in place, I don't use the whole strip each side as this would be too strong when removing the tracing paper from the turnout, you can see I am half way through putting them in place It is so much easier to build the turnouts on a small building board as you can easily rotate it and build in comfort on your work bench 2 Link to post Share on other sites More sharing options...
hayfield Posted July 11, 2016 Author Share Posted July 11, 2016 (edited) Next up is fitting the common crossing, until Exactoscale came on to the market it was the norm to use standard chairs cut in half where appropriate, and some still use this method These are the Exactoscale common crossing chairs, the sprue's contain one set of each of the following 1-5,6,7,8 & 10 The main difference is the A chair which is quite distinctive in shape, also there are the central parts of the block chairs. Look at the top sprue and you can see the central parts of the block chairs, The A chairs (slab and bracket) are also noticable These chairs (and the other special chairs) were designed for the Exactoscale P4 turnout kits, but can be used also for EM and 00 gauges as is or with minimal alteration, with the exception of slide chairs and check rail chairs Exactoscale instructions showing which chairs go where The common crossing in place, the Vee rails are longer than normal as the Vee has a slight curve, and the additional length alow me to put in the gentle curve, the excess rail will be cut to length later A closer view and from left to right Standard chairs Bridge chairs Block (X) chair Crossing nose chair (A) Crossing chair (B) Block Chair © Bridge chairs Standard chairs Now some may think this is quite obsessive, and my seem unnecessary especially if only building a few turnouts. At £4.50 for 5 turnouts I think they are worth the money and save chopping up normal chairs Edited July 11, 2016 by hayfield 6 Link to post Share on other sites More sharing options...
RMweb Premium Ian Smeeton Posted July 11, 2016 RMweb Premium Share Posted July 11, 2016 Cracking step by step there Hayfield. I suppose that the same principles apply to most scales/gauges? Would you do anything different for 2mm Finescale, for example? Regards Ian PS this, and a few other 'step by step' demonstrations should really be pinned somewhere (minus the interjections from knumpties like me). Perhaps a forum 'Masterclass' area is needed. 1 Link to post Share on other sites More sharing options...
hayfield Posted July 11, 2016 Author Share Posted July 11, 2016 Ian 2 mm finescale for me is a whole new ball game, it's so small !! Hats off to those who use it. It is very similar in build from what I have seen, though I do not remember seeing any special chairs and I guess the detail of things like the central parts of block chairs would be too small to be seen by most. I guess the principal is much the same though Link to post Share on other sites More sharing options...
hayfield Posted July 11, 2016 Author Share Posted July 11, 2016 I think that before I go any further I should explain the lettering on the Exactoscale chair plans, If you look closer you will see S1, P, PL & L1 Here are the instructions for a B switch with the letters and numbers by their respective chair positions. The numbers above and below is the chair / chair part on the sprue. Single number being a whole chair, two numbers 2 parts, three numbers 3 parts S1 is the standard 3 bolt chair, if you are using either GWR 2 bolt, MR 4 bolt or LSWR 3 bolt these will be in the same position P is the standard slide chair PL are the switch special chairs, though each one is slightly different L1 is the bridge chair which is used when 2 standard chairs will not sit next to each other M1 are the small chairs (but are only used in the Exactoscale slip kits) The other thing to remember is these parts are designed for use with the Exactoscale P4 kits, owing to the way the kits are constructed some bits are missing where one rail joins another. For example the centre parts of the X chair (its a block chair) is missing as there is a bar connecting the two rails together. The same is for chair position PL2 in the additional switch chairs, I will show the work around. Having said this most of the chair parts become functional even in EM and 00 gauges 1 Link to post Share on other sites More sharing options...
hayfield Posted July 11, 2016 Author Share Posted July 11, 2016 (edited) Before I show the fitting of the stock rails it may be less confusing if I show the following chairs On the left are the smaller bridge chairs, on the right the check rail chairs, which in P4 are fully functional These are the instructions for the 3 sizes of switch, The A switch has 5 slide chairs and 4 additional switch chairs The B switch has 6 slide chairs and 4 additional switch chairs The C switch has 7 slide chairs and 5 additional switch chairs In brackets are the number sequence for each of the right hand switches The pack below contains enough parts for a left and a right hand switch, can either be the same or different sizes The additional switch sprues. The left hand sprue at the top has the PL1 chairs , the rest being outer chairs. The right hand sprue has the middle parts of the block chairs from 3rd from the top to 8th from the top, below them are the inside parts of the chairs Edited July 11, 2016 by hayfield 1 Link to post Share on other sites More sharing options...
hayfield Posted July 12, 2016 Author Share Posted July 12, 2016 (edited) The real difficult part has now been done, the rest is more like building an Airfix kit. If you bought a common crossing its all been very easy Normally I fit the Vee fully in place before I do anything else, the reason behind this is that when I built one of my first turnouts many years ago I followed the SMP instructions and fitted the straight stock rail first, I was slightly out (or the plan was slightly under gauge) so when it came to fit the Vee it was off centre. With few exceptions now I fit the Vee first. With this turnout as its slightly curved I have not stuck the last 2 sets of chairs as these will be stuck to the timbers after gauging from the stock rails (this is the reason for keeping the Vee rails extra long) All the full chairs have been slid on the rail after cutting a slot in the rail between the 12th & 13th sleeper then soldering etched fishplates under it. This is to represent the rail join on the prototype. In the Exactoscale kits they have 2 separate rails and use functional fishplates Those with keen eyes will notice the check rail is in place using the check rail chairs, at the other end only 1 slide chair which is the 1PL from the additional slide chair pack, The 2PL chair is not supplied in the pack, I make one up by using a standard chair and trim off the inside bolt detail and fit a slide plate from a slide chair. Also there is a timber missing, this will be fitted last and will act as the tiebar There are 4 gauges holding the stock rail in place whilst it sets, the first is an Exactoscale roller gauge. The next 2 are the important ones the check rail gauges, in P4, EM and 00SF it is vitally important to get this correct for the crossing to work correctly. The last gauge is a standard roller gauge. As this has a curved stock rail the rest of the chairs are fitted by eye. If straight I stick the 1st chair next, when set I use a steel straight edge between the 1st chair and the crossing to line everything up I fit the chairs on the curved stock rail, gauge the crossing as before, then glue the standard chairs up to the black arrow by eye (the rest will be stuck down later after fitting the switch rails. On the first stock rail I have now fitted 5 slide chairs and two of the three parts of the block chairs 5 slide chairs first, then the 1PL chair, the next chair (position 2PL) is a standard chair with the bolt detail removed, then on the right the outer (not visible ) and middle part of the block chairs.

hayfield Posted July 12, 2016 Author Share Posted July 12, 2016 Fitting the straight(ish) stock rail Simply slide on the chairs and using a plastic fishplate attach the switch rail to the common crossing and start sticking the chairs to the timbers using gauges. You can see the block chair detail much clearer in this photo making sure the chairs on the stock rail are out of the way stick the rest of the chairs again using gauges. And fit the inside part of the block chairs on the switch rail Now fit the block chair centre parts (this is why we have not stuck the rest of the curved stock rail). A good view of the additional switch chairs Link to post Share on other sites More sharing options...
hayfield Posted July 12, 2016 Author Share Posted July 12, 2016 FISHPLATES I skipped over the fishplates, so here is a quick description for those who are unaware of these These are quite flimsy as they are but strong enough to hold the parts together whilst the solvent/glue drys Far better looking than rail joiners, they are also available in cast metal The second function they have is to electrically isolate the rails A view of the etched brass fishplates in place, there should be some on the switch rails but I want to keep them flexible Link to post Share on other sites More sharing options...
hayfield Posted July 12, 2016 Author Share Posted July 12, 2016 We are on the home straight so to speak, even if you are not using the special chairs its best to fit the straight switch rail before fitting the second half of the curved stockrail. Which I forgot to add another important point, just before the 3rd timber on the left there is a red line on Templot plans. This is called the set where you MUST put a slight bend in the rail Pre-curved switch rail roughly to shape, but to a slightly larger radius than needed, as you need a but of tension holding the switch rail to the stock rail. After putting the chairs on and using a plastic fishplate to join the curved switch rail to the common crossing, stick the chairs down using gauges from the curved stock rail up to the arrow (which is now highlighed in green) You will now see the switch rail should nicely fit against the block chair centres and hopefully against the stock rail. Now glue the remainder of the chairs on the switch rail and add the two inner chair halves for the block chairs Using gauges stick the remaining chairs on the stock rail using gauges. and fit the outer halves of the 2 block chairs (this should be automatically in gauge) As you can see the first two chairs are stuck in place and must be left to set completely before commencing the next stage The five slide chairs are superglued to the rail, then using a block gauge (or roller gauge with a flat filed into the outer ring) where (on Templot) there is a red line and called "stock gauge" glue the slide chairs in place so the stock rail touches the switch rail The two things left to do is to fit bonding wires between the adjoining stock and switch rails for electrical conductivity. Then fit the copperclad sleeper with cast slide chairs to make an invisible tiebar, trouble is I bought 2 packs of chairs and cannot find them. Replacements were ordered yesterday afternoon As you can see, other than the common crossing the rest of the build is so simple its not much more work than making a plastic wagon. If building in either EM or 00 gauges there is a small work around for the check rails and you use the 4 mm slide chairs not the P4 ones As for cost, its much cheaper making a few than one, but then if you are only making one don't buy all the special chairs, or recoup the funds by selling the surplus on eBay. If not buying either the Vee, or common crossing or even switch blades for that matter, the cost of parts will be between £15 & £18 no matter which gauge chosen. If you are not using the special chairs even cheaper OK you will need a set of gauges, though at a push you could use a digital caliper for some or all of the tasks A word of warning about the gauges, the chairs hold the rail at a 1-20 cant. The rail head needs to rotate in the gauge, if the gauge is either too tight and or too deep the rail will be held upright. This is fine for copperclad construction, but with the plastic chairs they will relax back into shape thus narrowing the gauge With ply timbers providing you use an appropriate solvent (C&L suggest Butanone) the bond is quite strong providing you do not go around smashing the rails. Use a stain to colour the timbers, if painting or dying them do it after building the turnout as the finish could affect the ability of the solvent to do its job Please feel free to ask any questions either via the post or send a PM 1 Link to post Share on other sites More sharing options...

hayfield Posted July 12, 2016 Author Share Posted July 12, 2016 (edited) Interesting to read before I start building again, particularly as in the past I always bought in the Vee / wing rails ready made and can't justify it on Brent given the large number of points to build. I do have one question, what should be used for check rail chairs in OO? Rich Vees and common crossings are time intensive to make, as I guess in low volumes they are hand made. But in components a few pence I now use the Scalefour Society Vee filing jig which speeds up production and is very accurate, prior to that I became very proficient in filling free hand and using a simple home made jig which doubles up for both filing the correct angle and holding the rails whilst soldering. Again you can make a simple jig from scrap to hold both the Vee and wing rail whilst soldering. The photo here shows how C&L do it with their 00 gauge turnouts, in EM and 00SF gauges I use a Check rail chair with one outside part cut off (see below for check rails) and the central block chair part not only holds the rail in place but blocks the gap However for both EM and 00 gauges there is no need to solder up the wing/closer rails to the vee as you can use a combination of both the common crossing chairs/cut up standard chairs and 1 (half) set of 0.8mm check rail chairs. I have made both an 00SF & an EM turnout this way and C&L use a similar method for the 00 gauge ones they sell. So a simple bit of filing up the Vee and 45p worth of check chairs As for check rail chairs in EM and 00SF I use the 0.8 mm chairs as described earlier in the thread 3 chairs on the check rail, 2 on the stock rail, cut off the unused part of the chair Slide check rail to the stock rail, glue the chairs and the cut off half chairs. Still works with 00 universal but a bit of a gap if you look hard enough Go to my work bench http://www.rmweb.co.uk/community/index.php?/topic/57911-hayfields-turnout-workbench/page-24 page 24 (too much waffle to read it all) post 578 & 583 has fuller descriptions Edited July 12, 2016 by hayfield Link to post Share on other sites More sharing options...

hayfield Posted July 15, 2016 Author Share Posted July 15, 2016 The turnout nearly finished, the sleeper tiebar system is in place just need to clean up the filler hiding the isolation gap and I need to fit the electrical bonding wires from the stock rail to the switch rail In the left is the brass sprue with 10 slide chairs, carefully remove the chairs and clean ip the pip which joins the chair to the sprue. Next is to clean up the chair to make the soldering easier, then cut the chair parts in two and clean up the cut with a file The chair base plates are soldered to a copperclad sleeper, make sure you cut an electrical isolation gap in the sleeper Solder the switch blades to the slide chair base plates Solder the outside chair parts to the RAIL SIDES Not done yet, get some 1 mm plastic rod and cut two cosmetic tiebars 2 Link to post Share on other sites More sharing options...

hayfield Posted July 18, 2016 Author Share Posted July 18, 2016 Two things I do to aid building turnouts The first thing is a simple method of keeping the sleepers in line, just tape a ruler in place and the ends will be perfectly in line The second is a simple sleeper/timber cutting jig. A small piece of board off cut and a strip of wood which is glued in place. Using a square cut a slit with a razer saw. I use a piece of thick plasticard as a stop. A clamp is used to hold both the stop in place and the jig to the bench, so both hands are free to cut the timbers in the required numbers all to the same length Just as an aside, I have built 2 x 31 timbered turnouts (B 7's) from the Exactoscale turnout timbering pack and have enough timbers left for another 15 timbers. The Exactoscale pack is far more economical than its C&L equivalent. The exact number of timbers used per turnout and crossing will vary according to both size of turnout and crossings use more longer timbers. In addition the longest Exactoscale timbers are much longer than the C&L ones 2 1 Link to post Share on other sites More sharing options...

After that, with a view to economising on timber usage, the length was generally reduced to 8'6". Questions are asked on this from time to time on the Scalefour Society Forum. You'll find a much more comprehensive discussion of what I've just said here: http://www.scalefour.org/forum/viewtopic.php?f=5&t=4795&p=44934&hilit=sleeper+length#p44931 HTH Paul Willis Scalefour Society Deputy Chairman PS - an excellent tutorial topic, and I hope that it encourages many more people into building finescale, customised, track whether that is in P4, EM, OOFS or whatever. Thank you for putting it out there. [edited to add PS] Edited July 20, 2016 by Flymo748 Link to post Share on other sites More sharing options...

After that, with a view to economising on timber usage, the length was generally reduced to 8'6". Hi Paul, Although the saving in timber (and ballast) costs no doubt played its part, the primary reason for the reduction to 8ft-6in sleepers was the arrival of prefabricated track panels. With 8ft-6in sleepers these could be transported within the loading gauge. Panels with 9ft sleepers needed to be moved as an out-of-gauge load, with all the extra inconvenience that caused. regards, Martin. Link to post Share on other sites More sharing options...
hayfield Posted July 20, 2016 Author Share Posted July 20, 2016 Paul Thank you very much for the information and especially the link to the Forum. My comment abut sleeper length was aimed more at the fact that these timbers were produced for all gauges and I was surprised that there were no 32 mm timbers for those who model in 00 (8'6" length) and 34 mm for both EM (8'6" length) and 00 (9' length). Still it is not too hard for most to cut a few timbers to length As I am migrating to EM gauge I must join one of the society's, and find a new local club. However my work commitments (working evenings) for the next 18 months may reduce my options. 1 Link to post Share on other sites More sharing options...
