Is this a Gauge 1 boiler

[brozier]

Hiya,

Can anyone identify these boiler parts? I got the plates with a part built Doris which hadn't been touched since 1972.



The larger former measures 4 3/8" High by 2 3/4" at widest point and 1 1/2" at narrowest.

The smaller is 3 1/2" High by 2" wide and 1 1/8" wide at base.

So this boiler would fit between frames that are just over 1 1/2" apart, is this too big for a Gauge 1 boiler?

Any ideas as to what engine? The tube plate is marked for 8 tubes one is central with the others arranged in a rough circle around it.

I've been practicing flanging on these before I start on some larger plates but it would be a shame for them to go to waste...

Cheers
Bryan

I would say no they look too big for gauge1 maybe gauge 2 1/2

Hi Bryan,

Having seen them 'in the flesh' they are almost certainly for a 2½" loco. I did suggest 'Dyak' as a first guess, but I think they are probably for 'Annie Boddie' which is a 4-4-0 tender loco from 1933. The dimensions of the former plates are not exact but close enough.

PS I just happen to have a chassis for an Annie which requires a boiler ;D

Wotcha John,

You are welcome to have the plates once I've finished practicing on them!

Bryan,
Hello again. Per Baggo's guess, these do indeed look very much like DYAK plates however the Dyak outside firebox has a somewhat shorter lower firebox than your plates appear to have. No matter, the builder could have made these long with the intention of trimming off later. A couple of other proportions seem to vary a bit from Dyak, the shape of the inner firebox crown for instance, but this could still be for a Dyak boiler. This is a Cad profile of the original Dyak firebox. The scale bar divisions are 1"

Hiya Harry,

Thanks for the drawing. This boiler is related to Dyak as the pattern of the tubes and proportions of the plates are exactly the same but the boiler barrel is bigger on Dyak (I make it 3 1/4"). On my mystery plates the boiler barrel diameter looks more like 2 3/4".

Baggo thought it was for Ana Bodie (any Body?) which he has castings for so I was going to donate the plates and formers to him for finishing.

Cheers

Bryan,
I built a boiler for the Dyak a few years ago and its proportions made it a puggish looking little thing, short and fat. A 2.75" barrel would have improved it's proportions however one certainly couldn't complain about a lack of water & steam space. I never got any steaming feedback on that one though, IIRC the fellow I made it for sold it off to someone else and it's disappeared into the mists.
