Hi John,
Well that’s a bugger!
Sounds like a job for the 3D printer to me. Take the existing plate make the hole taller, print a new shute with a bit sticking down to cover the not required bit of hole..... but I’m sure you’ll come up with a far more elegant fix. Keep up the good work!
Cheers Kerrin

Thank you Mike, Jim and Kerrin. I have removed the backdraught plate and I can now see exactly what's what! The cab is exactly 0.25 high, so I will raise the chute by that amount and cut the plate in the middle to leave it about one eighth inch high. Nobody is going to notice except me and the rivet counters...  John  20190629_120220[1] by inkaboat, on Flickr  20190629_120238[1] by inkaboat, on Flickr |

Better Bunkers!I must be bonkers, but I felt guilty about the rather utilitarian coal bunker, so I'd better make a better one. I have CAD, but like Jim, thin cardboard is more fun!  20190630_165734 by inkaboat, on Flickr I had some nice thin but strong sheet metal lying around, so I thought I'd use that!  It cuts and bends beautifully, but only once...   20190630_183128 by inkaboat, on Flickr Just a tryout: I forgot to put some 'ears' on it, but next time it will be fine... Anyone want a stealth fighter while I'm at it? John PS. Seriously. though, I'll probably make it out of galvo: I just wanted to see it was possible!  20190630_183521 by inkaboat, on Flickr

Blimey, titanium coal bunker! I wonder if any steam loco out there, anywhere, has a titanium anything! EDIT I looked it up, I can't find any reference to it being used in locomotives despite being used a lot commercially from the 1950s for weight critical situations. Apparently the russians have even used it for statues... On the flip side of the scale, my lip piercing is titanium and magnetite due to its hypoallergenic qualities.  Monument to Yuri Gagarin, made from Titanium. |

I too like CAD ( Cardboard Aided Design) , It's cheap , easy to repeat and easily 'adjusted to fit'. Only trouble is it doesnt convert to CNC directly!

Yes it converts to CNC (Cardboard Natural Construction) but its not compatible with water ....

I'll be using CAD soon when I do my ashpan, I have a few cereal boxes already put aside just for the job...  |

Hi Nobby,
The material guys at work reckon that titanium would be the best material for boilers! Just pop down to your local exhaust pipe maker & get him to make you one.....umm yeah ........
Cheers Kerrin

Back to the 19th Century!I gave up on the second Titanium bunker as it needs to be bent on formers to get it right first time. There are no second chances! So, this afternoon I made one out of galvo: here is the result before soldering and fitting. All done on the Axminster 3-in-1 Formit.  20190701_161934 by inkaboat, on Flickr Solder pasted side plate. I'll probably put a couple of flush rivets at the top, to be sure, to be sure...  20190701_162718 by inkaboat, on Flickr  20190701_164746 by inkaboat, on Flickr Snug as a bug and nearly done! A touch of filler and some black paint and it will be quite nice. Oops, nearly forgot: pump and plumbing, brakes, painting and lining etc. to do  John  20190701_173444 by inkaboat, on Flickr

More Airfix Bits!I couldn't resist it. I could not make this roof myself so accurately and quickly the traditional way... The body is now screwed together with the bulkheads. It is quite square, much to my surprise!  20190702_194039 by inkaboat, on Flickr The front is not attached yet. The roof just needs a slightly deeper lip at the front to retain it. Once painted it will be perfect!  20190702_194902 by inkaboat, on Flickr

I've not used solder paste yet, I need to have a crack with it. It's looking great John

Yes that's looking good. When I re built my tender I could not wok out why the left hand window was missing. So I replaced it on the re build.
When I finally ran the engine my back worked it out. A handle must have been used to pull and push the regulator which poked through it 🤓 Rather than trying to reach into the cab

I have done the same thing, made up a push pull rod for the regulator, a pull rod for the whistle and a twiddle stick for the injector steam valves.
I don't have to remove any side windows as the tender front lifts off to give me good access to the cab. My back doesn't bend like it used to back when flares, side burns and long hair were all the rage.

The water gauge looks quite effective, once toned down with paint it will look the real deal. More 3D printing, or a couple of volume control knobs? Nice job, anyway. Regards, Steve |

I have resisted the 3D printers but lately I have seem plenty of things being made by them. I might get the bug yet.

A little more progress on the detail this afternoon. The dummy handles seem OK, and I dumped the galvo apron in favour of a titanium one as I thought it was too thick and ugly! Much nicer now... BTW the buffers are not representative: I'll make solid ones! I just have to do the upper RH door and the aprons for the handles. Unfortunately, the tender body has developed a 'hump' midway. I have yet to work out how to deal with that! Progress! John  20190706_172308 by inkaboat, on Flickr I don't know if I've mentioned it before, but the stuff cuts and drills like butter! Mind you, it's sharp stuff: that's my blood on the front of the tender!  20190706_154924 by inkaboat, on Flickr |
