Has anyone got a line drawing (GA) of the Aspinal L&Y 'Pug' they could scan or copy for me. I've looked in vain through my "library" and online.
I'm particularly interested in the motion bracket dimensions (so need a front view in particular) and the valve gear detail would be good (Stephenson?) if that level of detail is available. I know there will GA drawings at the NRM at York, but I am re-building an existing model rather than starting from scratch - so I'm not sure I want to go to that degree of effort. I have however made a quick CAD drawing that shows where the slide rails fit so I can make something that works but it would be good to get the cosmetic dimensions correct too.
Strangely, although the model is generally very well built, as purchased it was in a non-running state and set-up for 2-rail operation. I'm converting her to battery electric but in the process want to improve a few parts that were clearly not made to the same standard as the rest of the engine (almost suggesting two builders - or perhaps modification after the initial build).
The motion brackets (for instance) are made as a single plate that fits inside the chassis, but the brackets on each side are lop-sided as made (e.g. non-symetrical) and crudely filed in parts but well machined in others. A number of "fudges" were also made to the chassis and motion to insulate them for 2-rail, which has resulted in some weak mechanical parts but hopefully these can be re-engineered fairly simply.

Ian,
Sorry, haven't got a drawing.
Do you have 'Locomotives Illustrated No.122' in your library?
It contains 9 pictures of the Aspinall pugs, 2 of which have quite good back-lit shots of the motion bracket and slide bar covers.
Might be possible to use GIMP or similar to manipulate scans of the pictures to give an end-on profile?
Let me know if you'd like scans of the relevant pages.

Thanks for the tip Andy and thank you also to others who have suggested other web/information sources.
Hopefully however - I will have a drawing to aid my 'Pug' efforts within a week or so. Thank you Mike.

I have just recieved a set of drawings for the Pug valve motion and motion plate that are exactly the information I needed to make the improvements. As the Member has contacted me directly, I'm not sure he wants to be named on this Forum - but I'm very grateful to him anyway.
Of course, all I need now if the ability to transfer some of this new information into modeling reality!
I've also been sent some very nice colour photos of the 'red goods' lining used by the L&Y. I may be tempted to try for the heavier (main) red line - but that secondary (1/16th full sized) line may have to be missed I'm afraid.
So thank you very much everyone who has helped out here - again it is much appreciated.

Ian,
Happy to be of help. The only reason I contacted you direct on this issue, rather than use this open Forum, was that the source material mostly came from a fellow member (not on the forum) who unfortunately has had his material plagiarised over recent years after supplying it in good faith. Also the drawings/photos on livery came from a recent L&Y Rly Society Journal, which will still be under copyright.
But I will pass on the word of warning re. the saddle tank plates to a wider audience in case anyone out there is planning to build one of these engines as running in pre-grouping period. As built there was only one line of longitudinal seam rivets, which was along the top of the tank. The staggered side longitudinal seams which are represented on models in all scales (including the latest Tower Models 7mm & G1 RTR engines), from photographic evidence, only seem to appear during to LMS period as and when the tanks were repaired.
Derek.
Thanks Derek, delighted to acknowledge your generous help - it was most appreciated.
With regards the loco - as we discussed via email - there are some obvious inaccuracies in my model - some of which can be corrected (e.g. there are no springs fitted above the running board) and some of which may not be (I think one or two dimensions may be adrift). It also has the vertical boiler seams you describe but as I am quite taken with the L&Y red goods lining - some 'artistic' license may be required.
What I think anyone (restoring a loco) will find is that there will always be things that have to be accepted as "that's the way they are" - or you may find yourself effectively re-building the whole lot from scratch. You have to draw a line somewhere.
But whilst there may be some compromises involved in any repair/restoration, hopefully there will be nothing that will detract too much from the pleasure of the finished engine.

Ian T
If anyone wishes to make a 3D printed version of the 'Pug', they can download the .stl files in 10mm:foot scale (for gauge 1) from https://www.g1-3d.uk/ . Once downloaded they can be fed into your slicer and rescaled appropriately for any scale you wish.
