Help me identify this 3 1/2 Guage Part Built 4-6-0 Tender Model

Hi

I got this model(s) when I purchased a lathe. I have tried for months without success to identify it.

If anyone has any ideas that may help, please please let me know. I have no drawings plenty of parts!!

Is it a Black 5, I think LBSC made one called Doris.

It's a Bonds Royal Scot designed for Bonds by Henry Greenly in the late 20's or early 30's, Drawings are available from Kennions , I know as I had a set delivered yesterday! ( I just bought a collection of 70 year old unmachined castings, the quality of which puts some of our suppliers to shame). It was designed as a 2 cylinder as opposed to the 3 of the full size, have driven an example many times and it steamed and ran well. One of the design options was greenly's double ported piston valves, these are on the drawings as well as the conventional piston valve cylinders. The design features a large roscoe displacement lubricator between the cylinders, where the third cylinder would be on full size, yours appears to have this.A dated design but there are a few finished ones I've seen running over the years. Googling Bonds Royal scot should provide some interesting answers, good luck with it. One of these has been top of my list for many years so I was delighted to chance over the castings.

A look at Station Road Steam's archive shows a couple of examples, including a part finished one

I've just noticed you have duplicates of some of the castings I don't have, if you decide to sell them in the future please let me know........

Many Thanks Buffer & Dave for your help and information..

Dave I'm sure there are the parts off 2 models, not sure of the history so don't know why. Will be in touch with Kennions, should make my puzzled head ease a little. I'll do some research now I have a lead. Are you anywhere near North Yorkshire, may be able to help ?

Hi Martin, you may like to look at these two scans.

Regards Nick.

Hi Nick

That's amazing, many thanks.

What a great place for helpful people.

Nicholas, thank you for posting the scans, very interesting, unusual to see the valve events specified in the advertisement, most designs you have to work it all out for yourself!

Martin, I'm miles away in Folkestone right on the Kent coast, we can see France from our kitchen window! but my daughter lives near Lincoln so we do venture north. If I can help in any way please get in touch via PM not an expert on these by any means but long admired them, one of the first loco's I ever drove and always wanted to build one. I've got most of the important castings except cylinders so failing building a time machine and getting them for 7 shillings (35pence) each, it's either machine from solid or fabricate them, the castings and the drawings arrived only yesterday so not had time for a really good look at them.

As I said you are welcome to PM me if I can help in any way.

Dave

Hi Martin , this model was not serialised in the building of it in The model Engineer unfortunately, which is a shame, which would help you alot in it's construction.There might be something similar I could find, but the measurements would need to be ignored, but at least you could see how the job is tackled! All depends if you build it or not, or restore your lathe! Dave is right good castings from Bonds!

Kind regards vic

Hi Vic

I am TOTALLY new to this and have been busy looking at old Model Engineer mags for help and inspiration. If you can point me out a similar build, I'd be very appreciative.

The lathe I bought was for restoration, which is now complete. It is a Granville CSL2 Metal Lathe, was non working and solid, now up and working. Just purchased a Sieg sc4, am hoping it will be just the job for the Model. It may be a step to far and the last thing I want to do is ruin a 70 year old project. So I'm not going to rush in.

Kind Regards Martin

It will be great to see this loco complete and running! Do let us know progress.

A welded steel boiler? Unusual in 3-1/2" gauge, but no real reason why not although a club boiler inspector might have waffle moments about it unless its provenance is known. Actually it looks quite new - its colour suggest black mill-scale rather than brown rust. While the rust on the other parts looks light enough to clean off without leaving pits.

A worthwhile project - plenty of advice on here, and for general machining and other metalworking advice there is available a goodly range of handbooks such as those sold by TEE Publishing. Not to mention two by one of this site's moderators!

Hi Martin, as Vic has pointed out, it wasn't in ME, but Martin Evens did a 5" gauge Royal Engineer in Volumes 140 & 141, which is a Royal Scot class. There are drawings for this, but as Vic has said, the measurements would have to be modified to suite your model, and a few details maybe slightly different.

Regards Nick.

Martin, Have a look at this Model Engineering forum post regarding the Bonds Royal Scot, you may find some help.

Cheers Nick, on the look out right now

Cheers Micheal

In the context of the boiler and the era (1939) of the design, if of steel construction then it may well have been gas welded or brazed. The fire tubes look neatly fitted, be it braze or weld. Now would be the time to decide when or if you would run it, and then in public or private. If in public then join a club and speak to the boiler inspector, for private use then you could conduct your own tests if you have the knowledge and equipment, though a club test is best ! Good Luck. Noel.

Thank Noel

The Boiler is steel, my lack of knowledge means I don't know if it is good or bad tbh. I believe there is a club up the road near Darlington which I shall be joining in the coming months.
