"The  only real tried and tested designs for G3 stopped in about the 1960's"

News to me Ralph - I have a half-built Collins-Wiese 'Flying Scotsman' that was published in Model Engineer in 1981 and Dick Allan's Gauge 3 'Dee' was published in 2011/12 and that didn't have an 'enlarged' G1 Dee boiler, it was re-designed, as was much of the rest of the engine. Dick also published a G3 'Crampton' design in ME two-three years after that. But there have been many 'new' boilers built by both G3 (& Association) members that haven't been published - a 'Battle of Britain' class engine comes immediately to mind, designed specifically to be a gas fired <3bl boiler by a G3 Member. It's also easy to forget the various new commercial locos (and their boilers) that have appeared in recent years - both from Kingscale & most recently (the end of last year) from Barrett (the J65).

There's no particular reason why methods used in G1, 16mm and the larger gauges can't be applied to G3, as there's nothing that different in the basic requirement apart from the track gauge. So whilst there may not be specific 'Gauge 3 building' books, it's not really a problem. I'm a great fan of Kozo Hiraoka, whose books on building American N/G logging engines (Climax, Shays & Heisler) could be considered as just being for 3.5" gauge builders but much of the design approach & build processes described in them would be equally useful to any Gauge 3 builder.

Robert, I am sorry that you feel this way... There is no affordable way in which we can interface a PDF scanner to the flat file data set that is our WIKI. It is not an indexed system or a relational database.

If anything it is more a Roladex machine than a filing system!

No it is not perfect. But of the options we tried, and I think there were a few, this simplistic program that would take anything that we threw at it and not complain. It uses a page description language that is identical to WordStar, it doesn't have any form of WYSIWYG word processor formatting.

The information IS generic since the  only real tried and tested designs for G3 stopped in about the 1960's. There have been no books on G3 construction since the mid 1920's. The most modern design for a G3 boiler is design no. 14 from Kieth Noble Harris's book. When I showed it to an "esteemed" boiler tester at Borrowash Model Engineering Society he then threw a temper tantrum that would have disgraced a teenage schoolgirl!!!

If you don't like what is there, then tell is what is wrong and how we may correct it.

Regards

Ralph

yes i have the inners done today (i used superglue for starters with wood glue after - to save a long hold!) it's a very quick build and i'm sure will be an ideal starter kit,for those who have not built any g3 wagon kits before. i will be ordering more once i have the current one finished.

I haven't looked at it for size/suitability but there is a De Winton design on the 16mm site which will have a vertical boiler - and I've seen a design for a G1 LNER Sentinel Railcar that would probably scale up but I can't think offhand where it was.

(Short pause) - Yes, Iris - here:   https://www.16mm.org.uk/resources/drawings/locomotives/

You have mail... I think the problem is that you tried to find specific words rather than subjects. Try the search again with "boiler".
No. I think the problem is that you and John know your way around and expect the rest of us to follow suit. G3 WIKI will remain unusable to others in its current state when the search engine cannot search embedded words in .pdf files.

And when you do get to the .pdfs they are generic boiler design approaches rather than specific tried and tested designs.

I have examined the G3 WIKI site and searched for all the terms used in your last email. Without weblinks, I will not access the site again as all search terms returned 0 results.

Depending on your ability at silver soldering... There is the "Porcupine" boiler and the "Smithies" types that can be found in the G3 WIKI or the on line  (out of copyright) version of KN Harris "Model Boilers"...

My pump is made from a Polly Models Eng Gauge 1 axle pump driven by a MFA Como motor and gearbox.
Had a devil of a time trying to find them on Polly Models Website - eventually found them in the catalogue.



Thanks Ralph!
Robert
