Go_West Posted July 14, 2011 Share Posted July 14, 2011 Have quickly put together some video and pictures of my schools class loco on test was hoping to do a better video of the finished engine covering the points in more detail but here it is What type of engine would you like? PS I did all this with out a business plan!!!http://www.youtube.com/watch?v=t8-LU2bHsyI Link to comment Share on other sites More sharing options...
Brightstar Posted July 14, 2011 Share Posted July 14, 2011 Hi gowest,Well done, it shows what can be achieved.Brilliant! Cannot wait to see the final product. Link to comment Share on other sites More sharing options...
The son of Triangman Posted July 14, 2011 Share Posted July 14, 2011 No one said you need a business plan to build one off locos gowest, you were discussing batch production, that's a different kettle of fish totally. Well done on making a nice one off loco anyway. Link to comment Share on other sites More sharing options...
Eric001 Posted July 14, 2011 Share Posted July 14, 2011 Superb Gowest, well done indeed you have excellent all round skills. Please keep an update on progress going. What you have is pretty unique. Link to comment Share on other sites More sharing options...
Go_West Posted July 14, 2011 Author Share Posted July 14, 2011 Eric001 What type of engine would you like to see Eric001?Will keep you up to date on the Schools progress what i wanted to do was see just how small an engine could be built? The tender is going to be more of a problem. I bought a King Arthur class the other day (EXCALIBUR) and was VERY impressed when running it on my track and this has a larger tender so might be another rebuild.

FinnerZ Posted July 14, 2011 Share Posted July 14, 2011 I'm know very little of the nitty gritty of how live steam works, but my running and general understanding is enough for me to understand how complex it must be. Well done. Link to comment Share on other sites More sharing options...

Eric001 Posted July 15, 2011 Share Posted July 15, 2011 Hello Gowest,As a little boy it was joy to see the A4s slow steaming across the viaduct at Durham station with that amazing backdrop when viewed from the park above. So Hornby chose the right ones for me. However I would really like to have a Coronation class.Getting back to your Schools, what are you changing in terms of the electronic controls? Did the Hornby design not suit your requirement?It looks like you are using brass on the body of the tender, are you doing the same for the loco body? I would imagine that Hornby would have used a thermoset plastic for theirs but I wonder if the bodies of their electric locos could withstand the much higher temperaturs. If so, that might be a short cut to making the LS loco of our desires with the associated quality of the present range.Has anyone tried that I wonder?Eric Link to comment Share on other sites More sharing options...

Go_West Posted July 18, 2011 Author Share Posted July 18, 2011 Eric001 Hi Eric001 you sound as old as me the answer to your questions are as follow'sThe Hornby controls for the servo motor are great and suite me fine all I have done is make it smaller and leave out the RED/GREEN lights I wish to try a yellow flashing LED in the fire box door this would be just ON when the engine is stopped and will start to flash just at the point that the steam enters the cylinders,A heat poof body would be great but the brass kit is a thinner section and for me better to make as all the design work has been done the tender is part of a 3 wheel SR West country class which I built and was my first convert from A3. I bought a Hornby WC set the engine and 3 coaches one being the observation coach very nice, for £200 from a shop and took the engine to bits using the wheels only and rods the front wheels were too big so bought off that web site E some thing a very early hornby old WC which has much smaller wheels and even adding heat resisting panels to the inside of the body, after about 20 runs it all melted even the engine name plate curled up at the ends and fell off so no good I will make a brass body when the schools is finished and that should be OK hope that clears up some parts for you.

Eric001 Posted July 18, 2011 Share Posted July 18, 2011 Hello Gowest,Yes answers my questions, but pity you hadn't replied earlier.You've just done what I was about to do. Bought a cheap Dutchess body on Esomething last night with the intention of fitting it to one of my locos to see if it melted. Hmm..from your experiment it sounds like it will.Being a plant engineer this is not my normal methods, to try things I mean. Normally I would investigate what the materials are and find out melting points etc but I can't find out what the chemical make up of the material is so I'm down to trying things which is alien to me.I've thought about heat insulating materials as you have already. I believe there is a heat sink material out there somewhere that has excellent properties but I have to find out about that. And no doubt it will cost a kings ransome.In the old forum someone told me the working pressure in the boiler was 2 bar (guage) so, from steam tables, the steam temperature is over 130 degrees C. What I would like to do is borrow a laser temperature sensor from work and see what the actual temperature of various parts of the loaco are. But, as you already know, we need a thermoset body or brass.I'm several steps behind you and I'll keep an eye out for your postings to see how you progress.All the best,Eric Link to comment Share on other sites More sharing options... Go_West Posted July 18, 2011 Author Share Posted July 18, 2011 Eric001 Hello Gowest,Eric its great to here that you are having a go and its with all comers putting forward help and ideas that this rebuilding will move forward I worked for Marconi for 26 years and in our factory there were loads of people with the skill to do anything and the processes to match I did find that a chopped strand type fibre glass that comes in round small tin's for car's "frighten to say too much" is ok and takes the heat from these small engines the hottest part is the supper heater back from that things were ok if insulated well.

I used it to repair a glass fibre battery box for a disability scooter, which had sheered where the screws holding the connectors for the wiring harness to the motor. Finished colour was pink, so it would needs painting.You could make the mould, by using epoxy filler or silicone rubber, from an existing model.I might try making a wooden pattern from obeche. The mould would need to be sectional and each piece of the loco glued together with epoxy glue to make the final model. I will have to buy a wood lathe and refresh my skills. I have not done any wood turning for over 50 years. An alternative for the boiler pattern would be to use a suitable size of dowelling, although this would only work for a paralell boiler, not tapered.I sahh have to do a bit of detailed research..

Eric001 Posted July 19, 2011 Share Posted July 19, 2011 Hello all,There's some good investigations going on here and I hope there is success by whatever means.Personally I was trying to make a new LS model to match the quality that Hornby have produced.I mentioned above about using an existing body from an electric train that might be a thermoset, and a good solution, but Gowest has already been there.However, I've been trying to find a heat sink material that could prevent an electric loco body, which I now assume is a thermoplast, from melting. I found a heat sink paste that might do the trick but it's experimenting again. Can't mention the company here but it begins with RS. It has a thermal conductivity of 0.65W/m2. So will that work, well..I have no idea but it might be worth a try.It will all take time gentlemen but lets keep trying. Link to comment Share on other sites More sharing options...
