Just to introduce myself Modelworks 9F restauration project.

[wiltsrob]

i agree..

in the personal sales area there is also someone selling a brittania kit if its still available...

iirc ... a modelworks brit ( albeit a slightly reworked one ) won imlec a few years ago ... just goes to show that they actually did a good job with this ...

Hello Chaps---------- and PONDOK. Yes, I've said much the same thing to our friend via the PM....I've never met the owner of STEAMDAYS but have spoken with him on a few occasions and have also spoken to people who have dealt with him----- verdict is he seems to be a reasonable sort of chap with a GOOD TRADING record... I would agree with you about buying this kit and hope our friend will make full use of all the available help, both on this forum and out there in "Clubland"...

[peterdebeus]

Big thumbs up to all of you for the help.

I have contacted steamdays that i will take it.
When it arived i will make a build topic with pitures etc so iff i need any more help
i will ask it there.

Thank again,

Peter

I've driven a Winsons Brit, modified so that it could actually run, and it was a wonderful thing, you'll enjoy it.

[peterdebeus]

Its a modelworks, dont know if thats much different?

[wiltsrob]

iirc... there is no difference.. modelworks was the re-encarnation of winson ...

[peterdebeus]

Ok thanks, that makes thing clearer to me!

What i would like to know, if there a place where i can find the vollume of the boiler, and maby a boiler building sheet, with the construction shown on it from the modelworks brittania boiler,

the local club inspector asked me if i can suply him so he can check them.
Boilers cant have over 8.5 liters to stay in catogory 1 and cant run over 6 bar when made from copper.
and they need a construction sheet where they can see the thickness of all the parts en so they can check the maximum vollume.

[ejparrott]

Strewth!

6 bar is only 88.2 PSI! The Brit should run at 100! assuming 6 bar limit, that means you can have a maximum water capacity of 51bar/lt....thats not much! My 3.5" Hunslet has a capacity of 4.54litres, and a WP of 100 so 31.34bar/ltrs. I do not remember and I do not know if a Brit boiler will hold more or less than 8.5 ltrs, thats a completly full boiler too remember, not the working level!

Hi Peter

I've just received your email, but I thought I'd reply here so everyone can see.

From the photos that you show above, it looks as though all the kits are included (eg the safety valves were among the very last items delivered before Modelworks went bust) so you should have everything apart from the injectors, which can easily be sourced elsewhere, the dome cover casting, which Blackgates sell, and the regulator valve linkage which is easy to fabricate with hand tools. My website gives more details about the kit contents and the few missing items.

The tender appears to have been very nicely finished - the only slight problem you might have is matching the green paint finish on the tender when you come to paint the locomotive.

The only boiler documentation that I received was a test certificate similar to the one shown in your photo. The boiler has a CE stamp (mine is serial number 511) but there is no other CE documentation. I don't have any boiler drawings and I don't know how thick the copper is. The boiler capacity is about 10 litres (measured by emptying the boiler into a pint beer mug on the day of the hydraulic test at my club, so don't rely on this being too accurate!) so it would be above the category 1 limit that you mention. The working pressure is 90psi, just over 6 bars. I suppose that Modelworks must have submitted boiler design documentation to get the CE approval, but I doubt that it would be possible to get hold of it now. So I guess the key question for you is whether you can get approval for this boiler to run in the Netherlands without additional design documentation. You really need to resolve this before buying.

If you can get the boiler approved, I would say go for it - if you follow the notes on my website, you should be able to build a model that runs very nicely. The only modification that I made that required machine tools was to replace the valve piston rings with PTFE rings, which a friend did for me in a couple of hours.

I'll be happy to give any advice I can if you do decide to go ahead.

Kind regards

John

my sugestion would be ... if the boiler is CE marked then a copy of the design would have to have been filed with Royal Sun Alliance..

Try sending them an email to ask is if it is possable to obtain a copy.

I thought CE marking just related to the manufacturer and not the individual designs, it's just to show that the manufacturer is working to the appropriate European standards.

[peterdebeus]

The company should be registrated to be able to give the CE stamp on the boiler.

Have sent them an e mail see what they think.
The boiler is over 9 litres so it has to be oround 5.5 bar to stay within the scale...
Think its time to make a stainless boiler.....

[angleseyrailway]

Peter,

Hello and welcome.

Do you have many 7.25" gauge railways where you are and are you a member of a local club?

[wiltsrob]

Dave.

Yes you are correct but to enable the company to get the CE mark the drawing has to be ratified..

There is no garantee the boiler will steam only that it will not blow up on first hydro testing.

robert

[peterdebeus]

What im tring to find is the declaration of conformity from modelworks that should
be suplied with each boiler they made.

So if someone could send me a copy i should be saved.

[Deleted]

I've emailed Peter a copy of my CE certificate. Interestingly it says that the boiler falls within category 1 of the PER 1999, and this document www.bis.gov.uk/files/file11284.pdf shows on page 25 that the limit for category 1 is indeed 50 bar-litres. So for a working pressure of 6 bar (87psi) the volume would have to be no more than 8.3 litres. Perhaps my beer-mug measurement of 10 litres was wrong. Modelworks did also make boilers for 7.25" A3s and for 4" traction engines, so they would have used the category 2 procedure involving inspection by their 'notified body' (No 0086, BSI Product Services Ltd) for these.

Regards, John

[peterdebeus]

Thanks again John,

My inspector told me the same.
So i need the origional certificate like you send me.
I need to be sure that its not over 8.5 litres
And i need a construction sheet of the boiler....

Its all quite difficult...

[GeorgeRay]

There is a Winson Brittania in our club the boiler capacity was measured at 10.5 litres and it works at 90 lb/in2 making it 65.2 bar litres.

[Deleted]

Yes, I've just filled my boiler to check again, and it took just over 10 litres.

Regards, John

[peterdebeus]

Ok, that will do it for me.

It will not be possible to get this boiler certificated.
problem, 8.5+ liters fitting in a copper boiler will automaticly be Cat2.
catogory 2 needs a CE certificate, if i can find that it can be checked, but because the originonal
boiler certificate was tested for Cat1 rules, it cant be tested to go in Cat2...

so this is not going to work, or ill have to see what the costs are to make a Cat2 boiler, in steel or stainless.....
