28 forum posts	JasonB, Thank you, having re - read all the forgoing, and re - studied the diagram regarding the back to back/wheel profiles in the article re track and wheel standards in the ME handbook, and your comment above, I now understand the dimensions. I had a fixation over the back to back dimension and was not taking into account the flange dimension! My apologies to all for being so 'thick'! Dave

3357 forum posts 112 photos 10 articles	Hi There I only edit the articles, I don't rewrite them. Also, some methods used by authors I would not use if building it myself. That does not mean they are the incorrect method. If Ray decides to change recognised standards, that is his decision. If I start changing anything then I would probably introduce major errors. All I can do with any article is edit it for grammar if needed and ensure all is in the correct order. regards David

498 forum posts 9 photos	Having just read the latest instalment of this series I have noticed that the drawing for the main spring shows the thickness as 0.78. Ray says that it is masive and would be rigid in the model, that is an understatement. By my calculation the thickness of this spring should be 0.054. How did I arrive at that, The spring on the original is 3/8" or .375, if you use a divisor of 6.85 this will give you 0.054. Why 6.85, this is arrived at by dividing 24" (the gauge of the original loco) by 3 1/2" (the gauge of the model). By the way the remaining springs in the stack are 5/16" thick or 0.045 in model terms.

498 forum posts 9 photos	Jason I do not agree, my sizes have come from the works drawing which shows 3/8" thick by 3" wide for this spring. This makes the model spring 0.054 thick by 7/16 wide. The drawing in M.E. is 7/16 wide but .78 thick. This would then make the full size spring 17/32" thick if the dimension should be 0.078 on the model. I doubt that they would have made the spring such a bastard size, especially with a stack of leaves underneath it. If you look at album 5 of David Clarkes photo's a very good view of the springs is available the top leaf is not massivly thicker than the lower leaves, this I think supports my argument.

25215 forum posts 3105 photos 1 articles	As the spring on the model is infact a "beam" that supports a coil spring (thats how I read it) then I assume the maker has made this one stronger as all the other leaves are just dummies. If it were scale size without the other 15 leaves to add support it would likely flex and risk going curve up If you are going to make working springs then yes the thinner size would be better. But as they are dummies there is likely to be a reason teh top load bearing one is thicker Jason

498 forum posts 9 photos	Hi Jason Yes that would be sensible. I must admit that I had not thought along those lines. Bit of tunnel vision on my part I fear.

100 forum posts 3 photos	hello has anybody fitted the cylinder mounting plates yet as i am having problems i have marked everything out ok and have checked it all but the plates seem to foul the tank mounting brackets any idea's tia regards peter
Dusty	13/01/2011 09:26:31
498 forum posts 9 photos	Peter As I see it, the tank mounting brackets are on the inside of the frames and the cylinder mounting plates on the outside. How do they foul? I have not started my build yet but have a full set of drawings plus the works drawings available.
Donald Mitchell	13/01/2011 10:11:48
90 forum posts 3 photos	Peter & Dusty, I have checked with Raymond on the phone this morning and he confirms that both the tank brackets, and obviously the cylinder mounting plates are on the outside of the frames. He acknowledges that they are very close, but if accurately made to the published dimensions it will all fit. Good luck, keep at it. Donald Mitchell Castle Douglas Bonnie Scotland

100 forum posts 3 photos	many thanks donald i'll have another go tomorrow and i'll let you know how i get on hi dusty i'm building it with the model engineer issues to see if there are any mistakes had a couple of problems but nothing to drastic regards peter
Dusty	13/01/2011 17:41:18
498 forum posts 9 photos	Peter I have started writing my lines 'I must read drawings properly before pontificating' I think 50 should be enough. In fact I should have looked at the drawings, having done so I can see that the brackets are indeed on the outside. I opted to purchase a set of drawings. Having built a loco from drawings published in a magazine I know that errors can occur in the magazine that are not in the drawings. It is almost impossible to check your own work when transposing from one drawing to another. I will start building later this year when all of you who have started, should have ironed out any problems.

Donald Mitchell	11/02/2011 17:45:33
90 forum posts 3 photos	Hi Engineers, I have just checked with Raymond and the radius of the expansion link slot is 5 11/16 Raymond has checked his master drawings (as supplied to ME) and the dimension is correctly shown on them. Donald Mitchell Castle Douglas Bonnie Scotland
peter ravenscroft	11/02/2011 18:05:14
100 forum posts 3 photos	thanks donald id worked it out to be 4-3/8 by blowing the drawing up to the correct size so it's nice to know the right dimension thge issue is 4397 by the way typing error regards peter

1 forum posts	Am I the only person building the Darjeeling loco. So far I have made the boiler & had it tested, got the chassis running on air & am well on with the cab platework. At the moment I am waiting for some 1/4" 'D' section to arrive also material to clad the boiler. I have not had too much trouble building building the loco but a few assembly drawings would have helped, at times its like a jigsaw puzzle wondering what goes where. Keith Rogers. Warrington
