midland compound me article??

[Michael RogoczParticipant @michaelrogocz56649]

does anybody knows if there was an article about a 5 inch gauge Midland compound by neville evans?

best regards

The only Midland compound model published in ME that comes to mind Michael – was an article by CM Keiller who wrote about his 2.5" gauge (1/2" scale) compound model (1937 – Nos. 1906 & 1907 – A Small Scale compound Engine)

He writes about them in 4240 and 4250, bit lost withing Penrhros Grange series

[IanTParticipant @iant]

He does Jason – but I'm not sure anyone actually wanting to build one would find too much there of practical use.

In fact he used the Keiller drawings as a partial basis for the line drawing in 4250. He also stated in an earlier article (4248) that he would make comparisons between the Keiller drawings and the ones he had from Mike Smart – but if he did so, I cannot find them.

Michael – there is a side view drawing of the Midland (Deeley) compound in 4250 – together with a frame 'outline' – the whole drawing is about A5 in size and not dimensioned. It's a good outline but not a GA by any means.

The 1937 Keiller article is a more detailed description of his engine (albeit in 1/2" scale) and has some useful info & drawings. I have it as a PDF somewhere if you would like to have it (please PM me your email).

I'd be interested in any other sources of Deeley compound info available in the public domain – as I acquired a part built Deeley compound a year or so ago and have just finished dissembling, cleaning and drawing the various discrete components into my CAD system as part of the (re) design process.

As far as I know, this engine has not been built to a published plan (I thought at first that it might be to Keiller – but it's in 17/32" for a start) and I have a lot of gaps to fill in (there was no valve gear made for instance). However, the work that has been completed is to a very good standard, so I think it's worth the effort.

The engine as received – it's not quite so rusty now… IanT

PS If anyone recognises this model – I'd be delighted to hear from them.

Did not know the OP wanted to make one just wanted the article (not a build series) by Neville Evans is the way I read it.

[IanTParticipant @iant]

Yes – you may well be right Jason but when I was looking for a 'published' Midland compound design, I spent some time trying to find one and only found the Keiller in 1/2".

If Michael is looking for something more detailed in the way of a 5" design – I thought I could perhaps help him.

Thank you all for your help.

I have a Maid of Kent in Midland compound outline and want to collect as many information about the midland compound as possible.

I like this engine and I'm thinking about to make it more to the origin.

Cheers

Polly Engineering sell the Mike Smart plans,

Now I have the set from PM. The set is mainly a collection of GA's.

I miss many details.

@Ian, do you know if there are any drawings from the 2,5" gauge loco where you sent me the PDF?

Cheers

Hi Michael,

I'm not sure I fully understand your question but CM Keiller was very much an experimental model engineer who also (unusually for his time) tried to keep his locomotive models to scale – albeit in 1/2".

As far as his model Compound is concerned – the drawings published in ME are the only ones that I know to exist – there were no other published plans or details of the engine that I'm aware of.

In terms of the full sized engine, it's possible you can also obtain GAs from the National Railway Museum (NRM) at York but I didn't manage to get too far when I was looking "online" but it may be better/easier now.

Regards,

 

IanT

O.S. Nock did a book some years ago on just Midland compounds. May have been in the “Locomotive Monograph” series.
Borrow from local library + scan/copy what you want. Might be lot quicker than trying to buy 2nd hand.HTH anyone.

Michael R.,

If you want Deeley valve gear drawing, try NRM.

If no go, try Inst. Mech. Engrs. (I believe that Inst. Loco. Engrs. merged with IME sometime ago.)

Rgds, John.
