    3.5" gauge live steam locomotive (first build!)

    Been a while since I've posted here so to make up for it here is a quick photo diary of me solving a simple problem: Here is the dome bush on the boiler: (note that there are no holes drilled, I have no idea how this boiler was hydraulically tested but I do have the certificate from Cheddar...

    Copper boilers and cast bronze domes

    Ok, I return with pictures as they are worth a thousand words ;D Firstly, the dome in question is not the decorative cover but is the inner dome and will house the regulator and safety valve. The boiler was manufactured by Cheddar Steam (UK) in 2002 and is just the boiler. The bush was...

    Copper boilers and cast bronze domes

    Yeah, on second reading my question may be a little hard to understand... The boiler is commercial built but it is just that, a boiler. It has all the bushes but not fittings: (ignore the toy steam engine in front of it, that was just for a size comparison) The large bush on the firebox...

    Copper boilers and cast bronze domes

    Just a simple question that I can't seem to find the answer too: With cast bronze domes for copper boilers, what is the thinnest the material can be? To give a bit of background, this is for a 3.5" (3/4 scale) steam loco with a commercial built coal fired copper boiler. I am building the rest of...

    Boiler feed pump (cylinder bore v pump bore) question

    Cheers for the help! I'll get round to making this soon and seeing if it works...

    3.5" gauge live steam locomotive (first build!)

    A minor update I haven't been able to do much recently as the loss of the Unimat has handicapped my progress as I am now lacking even a basic milling machine. Funds are also not present to buy the milling attachment for my new Clarke lathe. Anyway, I have managed to make the number plate! It is...

    Boiler feed pump (cylinder bore v pump bore) question

    Hello all! I am currently sketching out plans for a weir style boiler feed pump for my WIP 3.5" gauge LBSC Virginia. This will obviously be rather small (ideally less than 3" or 76mm in height) and so far I think I can do it. The problem is that I am unsure to what the ratio should be between...

    3.5" gauge live steam locomotive (first build!)

    The name plates are just simple castings. I got them with the boiler, no idea what supplier they are from. I only machined one to see what it would look like and isn't of the best quality. The Virginia name won't be used anyway since I'm going to name it one of the following: 'Jack 'O' Lantern'...

    3.5" gauge live steam locomotive (first build!)

    Many thanks! I will try to post plenty of pics! I haven't taken many so far and have a habit of not stopping when I'm going so I normally forget the camera until after I finished the part I was making ::) I chose to make my own fittings as practice due to my lack of experience with a lathe. It...

    3.5" gauge live steam locomotive (first build!)

    Ok, first post here for me. Been a long time browser and lurker but thought I'd finally take the plunge and post something! This is my first proper model engineering build and is being a steep learning curve. I have never had any training in engineering (other than a 'A' in design technology at...
