RMweb Premium Physicsman Posted January 14, 2013 RMweb Premium Share Posted January 14, 2013 Are those shed doors on the wrong way round ? I thought the diagonals always pointed up and away from the hinges. That's about the third new thing I've learned on the Forum today. I'd never had known that fact Stubby. Irrespective, another brilliant structure, George. You are making a lot of "converts" here.

RMweb Gold Alister_G Posted January 14, 2013 RMweb Gold Share Posted January 14, 2013 Are those shed doors on the wrong way round ? I thought the diagonals always pointed up and away from the hinges. I would have thought it should be the opposite - as shown - as the diagonal forms a triangle with the hinge edge and the horizontal to support the weight of the gate. Edit: Thinking about it, I'm wrong. as shown, the diagonal is in tension - which wouldn't work so well as the weak point is the join. If aligned as stubby says, the diagonal would be in compression, which works much better. Link to post Share on other sites More sharing options...
RMweb Gold Stubby47 Posted January 14, 2013 RMweb Gold Share Posted January 14, 2013 I'm not claiming this is 100% the case, but I believe it's based on simple physics... If the diagonal bar is let into the upright, the effort is transferred down the diagonal. If the diagonal is also let into the horizontal bar, the effort on the horizontal bar is away from the vertical. Thus, with two tailored joints at each end of the diagonal, and one pinned joint betwen the horizontal and the vertical, the triangle is self supporting ( and will also hold the addition of vertical planks). However, if the triangle is made as illustrated, the natural effort is down & away from the vertical, so is not self supporting. If that makes sense... Edit : Compression & Tension - that's what I meant ! Link to post Share on other sites More sharing options...
RMweb Gold Alister_G Posted January 14, 2013 RMweb Gold Share Posted January 14, 2013 Beat you to it, Stubby. (see edit above). Just to add that if it was a metal gate, it would probably be the opposite way, as metal is stronger in tension than compression. Think supporting stays on railway crossing gates...

georgeT Posted January 14, 2013 Author Share Posted January 14, 2013 Thanks for the help lads, l have modified the doors, and had a bottle of lager, feel better now and the shed looks better too, "l think its the inpending visit of Sir Lune that has got me in a tizzy" HaHa thanks again. georgeT Link to post Share on other sites More sharing options...
georgeT Posted January 15, 2013 Author Share Posted January 15, 2013 A friend had given me half a dozen or so long flexable track that were taken off a layout that was broken up, they were a bit worse for wear, and covered in paint, so l thought l'd start by removing all the webbing between the sleepers, bit of a pig but l think it looks more realistic and is so much easier to ballast, once you put all the sleepers in order. georgeT Link to post Share on other sites More sharing options...

Hi Stubby, you are right, it is to stop the outer timbers dropping, well spotted. Andy. Link to post Share on other sites More sharing options...

RMweb Gold mudmagnet Posted January 15, 2013 RMweb Gold Share Posted January 15, 2013 Great work as normal George. I did the same thing with the diagonal braces on a door that I made, until happily showing at railway club when someone 'helpfully' pointed out my error! Since has been corrected!

georgeT Posted January 16, 2013 Author Share Posted January 16, 2013 Hello Richard, Yes it was a pain to hear that l had put the doors on wrong, but thanks to Stubby47 and others for putting me right, that they are now hanging correct, we learn something everyday. With 'Abbot's Mead' l have decided to model it in 1963, the main reason l dont fancy trying to paint some of my locos in lined out green (eg the terrier for one), lifes too short to be fiddling around with all that masking ?? l know BR mixed traffic is hard but not as fiddly as southern. georgeT Link to post Share on other sites More sharing options...
RMweb Gold Donw Posted January 16, 2013 RMweb Gold Share Posted January 16, 2013 If you ever make a planked door (T&G for a cupboard) you will know it has to be that way round for the brace. The problem sometimes comes because some plastic kits use the same moulding for both doors so one is always wrong. A lot of heavy duty planked doors are ledged and braced which means there is a frame round the outside. Much less likely to warp. Don Link to post Share on other sites More sharing options...

Andrew P Posted January 19, 2013 Share Posted January 19, 2013 Hi George, Thanks for a wonderful few days, and all the work you have done on Trebudoc buildings, as expected they fitted in a treat. I am looking forward to seeing Abbotts Mead develope, some great work so far on the buildings mate. Cheers again, and all the best Andy. Link to post Share on other sites More sharing options...

Great video again and very instuctive. All the best Andy. Link to post Share on other sites More sharing options...
alant Posted January 20, 2013 Share Posted January 20, 2013 Enjoyng the videos George, keep em coming! Never tried DAS before, made plenty of buildings over the years with embossed card, plasticard and brick papers etc. You get some great looking results, will have to give it a go.

georgeT Posted January 20, 2013 Author Share Posted January 20, 2013 Hello Alan / Andy, Really made a right cock-up with my little plate layer's shed, and l was going to scrap it, but as l started to cut the bricks off which were wrong l discovered you can scrape away the plaster until all the bricks are gone and you can start again. The front of the shed you can see the plywood where l scrapped too much off, but l think it will be ok when l paint it, ? unless l get Andrew P to paint it for me ?so l got on with the build, and added a chimney, just have to put some more DAS on it.

georgeT Posted January 20, 2013 Author Share Posted January 20, 2013 Hi, When Andrew P came up to the grim north and stayed for a few days, he worked a track plan out for 'Abbot's Mead' which inclued a 'Y' point 2 'RH' point's and a 'LH' point, in which l will have a single through line and a short bay platform,and a good's shed and a single track into the shed, away from the station in front of the fiddle yard, also l want a cartridge style fiddle yard, There will be two tracks, going into the fiddle yard, and today l have managed to make a start on one off them. l like to use strong double-sided tape to stick the track down, l find the sleeper's are far to thick for pin's, plus you don't have hole's everywhere, George Link to post Share on other sites More sharing options...
