Mind you, I think there should only be 5 across the top John I've just had it on good authority (JJ's) that it is a case of five on one side and half a dozen on the other! However, it's only a model.... Offset perhaps to avoid wetting the people on the other side of the boiler! JB |

Hi JB,
On the LNER B1 - Bongo- I found that the boiler washout plugs were not spaced the same on both sides of the boiler. Just a cunning thing to catch you out!!
Chris.

Thanks Chris. Isn't model engineering wunderful?
BTW will you be with Bongo at any time this weekend?

JB The top plugs are off set as you correctly surmised so that the water jet when removing scale doesn't go straight through and out the other side and the scale then goes down the side of the firebox to the foundation ring where it is fished out through the mudholes. There is an excellent BTF unit film called Wash and Brush up which shows how to wash a boiler out. www.youtube.com/watch?v=WG1uRu9sPiw&feature=player_embedded#! should get you there. |

Absolutely fascinating George, I learnt a lot! Mind you, a modern(?) eye can see how it might have seemed much easier to management to rather change an oil filter on a diesel engine than to employ all those people with the quite obvious attendant demarcation opportunities! Imagine clambering into a still warm firebox!! JB PS: I'm not going to make a new firebox wrapper ..... |

Nothing quite like a warm firebox on a cold morning...... Thanks for sharing the film link hadn't seen that one for some time.

There are washout plugs all over the place. A total of 9 on the drivers and 7 on the fireman's side. But then some artistic licence is always possible and I may have missed one or two. There is a fantastic web site which I'm sure you all already have bookmarked www.fraserker.com/winson/britannia_pix/page_01.htm (Its also available from JJ's Britannia builder site.) It's just missing a couple of pictures from above, but that's me being picky  |

There are washout plugs all over the place. Yes, after seeing that film I have realised this! I'll put the two in at the bottom edge each side of the firebox, and six on the backhead, and that will be enough for me. I'll leave out the cleverly placed ones on the curved corners....! JB |

Hi Shawki, yes I have admired your work there when DJ posted a link. Your work is fabulous and the speed in which you build is truly amazing. A sign of great confidence in what you do, high skill and a vast amount of experience too. I'll be asking your advice for years to come I'm sure. I have so much to learn, Doncaster's tender I have found relatively easy although when I first read Don's notes I was like "Christ what have I taken on here?" but once I got into it and slowly understood what Don was saying I began to feel at home. Having now advanced a fair way with the tender I'm starting to plan for the loco itself and have to say I'm getting very excited about it, but beware I'll be asking lots of very newb questions in the future... Merry Xmas Pete |

Pete , you are spot on , once you break the complicated unit into small parts it is not that hard , I normally spend good time on reading the plans , finding out what is straight forward and what needs more thinking before cutting metal and may be some modification ( that are practical and does not affect the engine general look ) . Knowing the engine well is halve the job done , the rest is just work . Thanks for the kind words . This is a great forum , I learn a lot from it . Merry Christmas .

Hello My Friends
I just found this thread or I would have chimed in with this bit of info earlier. When fitting up a boiler jacket it is a good policy to put a few wraps of masking tape around all the bits it is to fit over. Then when all is fitted and before final painting the masking tape is removed. This will allow for the thickness of the paint and after painting things will still fit together nicely. As we all know, a small change in diameter will affect the circumference quite a lot. I learned this one the hard way...
Happy Model Building
Jack

I made a manifold quite unlike the LBSC one and hopefully more like the real thing. The Manifold is in the mini hearth anointed with Cupalloy silver solder paste. I wouldn't use anything else for this sort of job, as little cleaning up is needed afterward. I know I spend a lot of time in France but these are the only frogs allowed in my workshop!  Finished manifold mounted with nipples attached.  Add a few 1/8" pipes (not the 5/32" ones in the words and music) and it doesn't seem to be much out of scale at all! What do you think? JB  |

I've also been busy with the firebox doors: I can't resist stainless steel; it's so sensuous when polished! The firebox doors have been waiting for the operating arms for a while now. I had problems sizing them, because the firing hole is bigger than the LBSC spec, so I had to abandon his dimensions. It was just a matter of trial and error: a real trial and my error! Three goes with dummy strips and I had this result in 18g stainless plate held on with 2mm SS socket head screws sitting in little brass stand-offs just bigger than the thickness of the arms.  Yes! The doors do open! (though not quite enough right now....)  Nothing much to pass on really, except I find hacking out stainless sheet that won't go in my bench shear is more easily done like this, with two bits of tool steel holding the work in the vice.  |
