96RAF Posted October 23, 2016 Share Posted October 23, 2016 Job well done Ken, that really looks the business and the shape should hold its form against the pressure OK without distortion and as a bonus more volume than the datum boiler as well. I well remember a test job in my apprenticeship, we had to build the Eiffel tower out of wire. The object of the exercise being to learn about melting points of various solders. If you got it wrong then it all fell to bits.Rob Link to comment Share on other sites More sharing options...
Go_West Posted October 24, 2016 Author Share Posted October 24, 2016 Fishmanoz you must keep the kitchen sink as it's the only place to dump red hot bit of metal when soldering so if WTD needs a lathe what better place than bathroom as most of my work is rubbish the first time round!apart from that once you have a lathe theres no end of things you can make even wooden things like bowls still as Rob said I'm very pleased and a bit relieved that such a small tender can in the end carry enough water to make this model viabl. These engines that Hornby produced are with out doubt made using parts that can be built into just about any type of engine and it would be great to see them build a new engine as all the hard work they did and testing was done, with over 14000 hits on this engine build if only half were live steam operators I still thing a small production fun might be a good idea.

96RAF Posted October 24, 2016 Share Posted October 24, 2016 I drool over the model engineering lathes everytime I go into Machine Mart, but I can't justify around just under 500 quid (and then upwards) for a very nice, but what will be very seldom used, bit of kit. re - new run of live steam - Hornby's cry off would be on grounds that a short production run wouldn't cover their setup and marketing costs, having probably not made much if any money the first time around with what was a high risk product. Its the sort of job I feel that they could sub-contract out to cottage industry as a specialist order product, along with the associated product support for spares and advice.Rob Link to comment Share on other sites More sharing options...
Go_West Posted October 24, 2016 Author Share Posted October 24, 2016 Robi think that a close look at all the parts and working out if they are all needed to be so complicated and if in fact some could be left out making assembly easier and with less parts a bit cheaper I'm sure that CNC work today must be cheap as chips for run of a thousand say my son in law works for a coumpany that makes tooth paste it cost them 2p a tube but in the supper mark £3.50 and like with these engine I'm sure if the price of parts is worked out they would be under £100 so could they be sold as built or part built as they did with TITANIC on a magazine run and the like this would keep down the assembly cost which might be the biggest part of the overal price.I buy a lot of stuff from china as you just pay to much here for parts take a transistor BC548 in the U.K. It's about .50p each plus PP in China you can buy 10 for that price and they still have to send then half way round the world.

Go_West Posted October 24, 2016 Author Share Posted October 24, 2016 Rob it makes me think of Henry Ford he worked out by not using washers on his cars saved him money in time and materials some one once told me he asked a wheel manufacturer that was contracted to make wheels for his car that they had to arrive at his assembly plant in woode boxes 10 wheels to a box and the boxes were 4 ft square the idea being that once the boxes were taken apart the 6 wooden panels were the right size for the floor sections of a model T Ford car?

96RAF Posted October 24, 2016 Share Posted October 24, 2016 The car industry is a worthy model for this type of thing KenI remember reading a book about them where they had a fault (vibration causing it to loosen and become a danger) on the steeering on a particular car but to put it right the modified bracket would cost 1 cent more on a 500 dollar car so they didn't do it, opting to fix any that did work loose as they happened. Multiply that 1 cent saved across hundreds of thousands of cars sold and you can see a little means a lot at day's end. Some of these old boys were very canny when it came to such things. My old boss was one such gent, which is obviously why he got rich and I just worked for a living. Link to comment Share on other sites More sharing options...
Go_West Posted October 24, 2016 Author Share Posted October 24, 2016 Rob we are one of the same worked and not rich but happy. Starting with the rear lamp I bought some LNER lamps and started to built the system which was just a simple power unit with a red surface mount LED The drawings here show the basic construction the heater for the tender was going to be just small sockets the size of the sockets were bang on the for the solid wires coming from the heater and in this way the assembly servicing would be a little easier.so the rear lamp/media/tinymce_upload/e998cccc75b97ca82de77580b83a6810.jpgI made up the printed board first just a small square of 1 mm thick board. To this two strips of brass about 3 mm wide and 10 mm long with a fixing hole to pick up with the brass chassis.Once this part was done it was screwed in place on the back end of the chassis and the body fitted in position./media/tinymce_upload/7cfb5b7ba1c21b35bf5eb49739e4273e.jpgNow a hole was needed to pass a small fibre optic cable through. Choosing the right size drill the back left hand corner of the body had a small hole drilled through.This action was continued so that the drill would leave a mark on the printed board so giving the correct position for the small LED./media/tinymce_upload/2c7aed36708ac3180d378113f3483c7f.jpgNow by removing the body then the printed board the rest of the board could be marked out and the components soldered in place./media/tinymce_upload/a7d66bd7c565074acdc160279d21ac2c.jpgWith the board complete a quick test is all that is required and by connecting the two brass fix tags to a 9 volt battery the little LED came on it would be a bit brighter on 16 volts but we see then how it looks on the track when we get to test the steaming side of the tender./media/tinymce_upload/499ac6cb57e7c167d4ababd07e01e5da.JPGWhat we need now is a lamp so removing the small glass lens from the front of the lamp then drill the same size hole as we did for the tender body drilling right through and out the back of the lamp./media/tinymce_upload/3a4ecd615beff589923acf44dc470e2b.jpgThe fibre cable will be the main support for the lamp so taking a short length of cable by holding it close to a hot 60 watt soldering iron but not touching the iron tip with in a few seconds the end start to melt and mushroom./media/tinymce_upload/207eb8a618d3d9dc7fd44034204d65f6.jpgIn the picture here we have the lamp and the fibre cable in place this now is fitted in the body and the fibre cut to length and the end once more heated up and mushroomed over so it is now captive in the body some glue just to stop it turning and hold it in place is required./media/tinymce_upload/214cf9df093f8c77d2871f07b9e6df0c.jpgThat’s that part completed on the track and it lights ok was a bit of a squeeze but it in and working looks a bit cockeyed Link to comment Share on other sites More sharing options...
Go_West Posted October 25, 2016 Author Share Posted October 25, 2016 Steam Testing The Tneder The tender was connected to one of my best A3 Flying Scotsman which as it was in tip top condition would use the steam generated by the tender most efficiently./media/tinymce_upload/ebd43bdfd89de5bad82ebf8ff237a093.jpgWhen the steam pressure was enough for the engine to move off the time of its departure was recorded. The engine was to be left running at a set speed until it stopped due to lack of water and the time taken.By the time the engine had stopped running the time recorded was 34 minutes later so just in the 30 minute target but it was hoped it might make 40 minute but no.

Rog RJ Posted October 25, 2016 Share Posted October 25, 2016 Still a good result. Has the boiler swelled at all? Link to comment Share on other sites More sharing options...
96RAF Posted October 26, 2016 Share Posted October 26, 2016 It may run longer with the S69 loco Ken as I believe the cylinders ended up a different size to fit the frames and fuel consumption is all down to combined efficiency of the total rig.

Go_West Posted October 26, 2016 Author Share Posted October 26, 2016 Rogas for the shape of the boiler if it has changed shape by just a millimetre then the body will be jammed in place and will be hard to remove as it was a tight fit in the first place as for the 2 different engines the cylinders did end up the same size so no change there but the way the engine works is different and might make the running of the S69 better or worse we will find out when the complete engine and tender is tested it would be great if it was better on steam than the A3 as when this engine was first built it turned out to be very good on coal and water.

Go_West Posted October 26, 2016 Author Share Posted October 26, 2016 yes even i have to read through pages to find out whats going onWell today had a day off and took the grand children to the Lynton and Barnstaple railway for a ride on the train seeing a steam engine working is always a treat and they enjoyed it /media/tinymce_upload/26298a79a6ff5f665efbce1ce3be7746.jpgThe L&B is not far from me and every time I go some thing new has changed The railway was opened in 1898 and the picture above is Woody Bay station in the 1930's the station is now the starting point of the line. The line was closed in Sept 1935.This gave me an idea with a track 1ft 11ins could the Hornby parts build an engine like this?/media/tinymce_upload/e01b89f69b9083f18e045258781f922a.jpg/media/tinymce_upload/8773dc777fd9781d4b40b581f271a8ce.jpgbut before i consoder the next engine to rebuild our tender needs some coal i have discribed this before i think but will go over it once more here.

96RAF Posted October 27, 2016 Share Posted October 27, 2016 Pretty little engine Ken.I love the way these new age steam railways look after their fleets. Questions - is there a critical size for cylinders below which they cannot work efficiently enough to run reliably, and could they be made from tube as opposed to the brass block method to save space.

Go_West Posted October 27, 2016 Author Share Posted October 27, 2016 Hi Robif it was thick wall tube that could be machined to the right size should work I thought of the narrow gauge as they could have the 00 track but the model would be larger so getting the bits in would be a easier job.

Go_West Posted October 28, 2016 Author Share Posted October 28, 2016 The Tender Coal CoverTo make a cover to hide the safety valve and water filler access points what you need is some coal some fibre glass dent repair filler and a small bit of aluminium foil and the tender./media/tinymce_upload/9741aaf082c63e533371e5bdd75c28f4.jpg/media/tinymce_upload/62ba935e9491ebd22bd47f1b6158753a.jpgFirst paint all the edges of the tender top part tool boxes and the like with oil to stop the fibre glass sticking to these parts of the body and making it easier to remove once the fibre glass has set./media/tinymce_upload/634cb4f4c67d998dfd2dc0f107fd52e8.jpgThen press the foil in over and around the different parts of the tender top area tucking it around the filler ands valve and both sides of the protruding top section of the boiler./media/tinymce_upload/c923b8d289c1e0425176052b50878cb7.jpgCrunch up the coal into very small bit that will look the right scale.Mix up the fibre glass and spread it on top of the foil do this bit as quick as possible so you get time to add the coal./media/tinymce_upload/c95bb1bcb27c7db1c8e91fb2ccd51d43.jpgPush the small bits of coal into the wet fibre glass pressing home nice and tight to the contours of the tender body and the fittings./media/tinymce_upload/e1edc4249a0aa5914956296c4783bf18.jpgOnce you are happy that the coal is even and covers the fibre glass drip some super glue all over the coal to fix it in place permanently so that handling the coal cover does not loosen any of it./media/tinymce_upload/6872dd9efed4efe18d0384adced6028a.jpgClean up all the edges of the cover filing off unwanted parts and making it an easy fit in the top of the tender body./media/tinymce_upload/55136feea4296129c05f5620ab1a359a.jpgIf you have any parts that show the fibre glass then a little black paint on a brush will cover them up fine, the notch in the coal is where the tool box sits./media/tinymce_upload/75d019160149d2bd23d2954778b415b2.jpgAnd with the coal in place it’s a real load that they picked up from the coaling station must be a long run. My mate lived next door to the railway line of the GER/LNER just outside Chelmsford and he and his friends used to walk along the railway line picking up cups and saucer thrown from the trains and if a train went by the fireman would throw bits of coal at him or turn on the hose and drench him with water.I can remember going round is house years later and getting a cup of tea with LNER printed on the china.Now we have a complete tender finished and working with the coal so next it will be finishing off the engine and a complete system test.

96RAF Posted October 29, 2016 Share Posted October 29, 2016 Is there a blow hole or when the safety lets off will it eject the coal load as an indicator Ken. Looking really good and looking forward to the full trials. Link to comment Share on other sites More sharing options...
Go_West Posted October 29, 2016 Author Share Posted October 29, 2016 Hi Robnot sure what would happen if this valve lifts Hornby fitted this valve as a backup to the engines safety valve should something go wrong I have only seen this valve lift a couple of times in all the years of running these engines but just shows it's been called on to do what it was designed to do and that's to release over pressure in the system. Good old Hornby thought of everything. Link to comment Share on other sites More sharing options...
Go_West Posted November 1, 2016 Author Share Posted November 1, 2016 Must get on with the engine now but have been busy on coaching stock as it alright having a GER engine but it needs some GER coaches so under the general page of the forum I have with the help of other forum people built 4 suitable coaches which might just pass once i start running the engine.

Go_West Posted November 6, 2016 Author Share Posted November 6, 2016 /media/tinymce_upload/699673ef0cc61ece541a8533d4cb0b6c.jpgNow the flickering fire and the control board needed to be housed inside the body and there was the smallest of space left just behind and above the electric motor.At this point was the largest part of the fire box so did give the best location. Then there was the LED for the indication system of the regulator position to consider. This LED had to shine through the fire hole door in the back head of the boiler. To a achieve all this an “L” shape bracket was made and would be screwed to the top of the servo gear assembly. The Control board being double sided printed board had a square of brass soldered to the under side and was also held in place by the same fixing screw for the “L” shape bracket all as the drawing here./media/tinymce_upload/f57f0a2cc66c7eab01dd2a550aeb6c97.JPGIn the picture is the flickering LED with its end filed down flat. /media/tinymce_upload/a772a97b0d0511cf092acbf6d08c39c1.jpgThe LED was glued to a piece of printed board and fixed in place with a small screw the other side of the LED had a small DIL socket plugged into the 2 LED wires which you can see in this picture.The other socket in the top left of the picture is for the super heater wires to plug into making the complete assembly much easer to service at a later date./media/tinymce_upload/695cf5a993035434c04f00f85666ad07.jpgThis is the unit with all its wire in place ready to fix to the servo motor gear assembly./media/tinymce_upload/0e4aa19da01033ee6cead77d3d0b9cac.jpgIn these 3 pictures you can get a better idea of the units location with the 2 power cablesgoing to the tender. Also note the copper pipe which will take the steam from the tender to the engines supper heater./media/tinymce_upload/e1992ca94dc8bf11950b06451febbaee.jpgThis still leaves just enough room for the crew to work away in the cab./media/tinymce_upload/eaef91b01e9ca17800739b654f2411d9.jpg Link to comment Share on other sites More sharing options...
96RAF Posted November 6, 2016 Share Posted November 6, 2016 Ken that last picture shows how much thought has had to go into modifying the original FS arrangement so as to end up with what is a very nice tidy engine. And we mustn't forget all this is in 00 gauge size. I hope it rewards you for all the effort by being a very good runner and it is certainly a worthy tribute to your grandad's memory as a loco builder himself.
