As I mentioned earlier I don't own rollers plus since the sides are already cut to size I wouldn't be able to use them anyway with the radius being do close to the edge. So I had to make a plug to shape the sides too. Pic58 This picture shows the former that I used, the original plan was to clamp the top edge of the tender side between two right angle pieces of steel with one if these having a piece if alloy of the correct diameter which had been cut lengthwise bolted to it. The two right angles where clamped together with the one without the alloy bar bring positioned higher than the other. The reason for this was to reduce the possibility of the brass sheet slipping out when forced around the former. Now this worked perfectly for lengths of brass 1mm thick and 300mm long which I used for testing how much material was needed to be held between the right angle to give me the correct shape, remembering that these tenders have a radius close to the top edge which then flattens out for about 5mm IIRC. Unfortunately when it came to forming the sides themselves it wouldn't work, well not so much it wouldn't work more that I didn't have enough strength to form the brass which is double the test piece length and thicker too. So plan 2, leaving the former in the vice I laid the tender side on it, if you look at the picture and imagine the brass lying on top with the section to be curved over the alloy bar. I then calculated exactly where the brass needed to be and screwed a length of timber along the bottom edge into the top if the bench. Next was to clamp another piece if right angle along the top of the brass trapping it at the correct position over the alloy former , this allowed me to then beat the brass around the former using panel besting hammers. Hope I explained that well enough, once I had decided to do it this way each panel only took a few minutes. Attachments:

Pic59 Once the tops had been done it was an easy task to do the front curves using the former as originally intended Attachments:

Pic60 With the sides rolled I could now assemble the panels, rear was done first, followed by the front after I had first turned up a short length of brass which was drilled, tapped, stepped and brazed into a matching hole for the step in the front panel bottom right. This is for the water gauge once it's built, the drawings weren't very clear here as they only show the hole for the gauge on the locker panel, which yes has to be done too( I did both at the same time while clamped together) but since it's a locker and not part of the water tank I can only assume that there is some sort of connection pipe running through the locker from tank to gauge, anyway I've tackled it with my brass tube which the gauge will screw into later. Finally the side panels were brazed on and I finally had something that looked like a streamlined non corridor tender...  Attachments:

Ok that's all for today , will do more tomorrow, I reckon he's got a DJ style team doing all this for him! JB |

I wish.. Err actually no I don't, after all what's the point in that? Dont worry JB this thread is nearly up to date so things will slow down and once I'm back at work they'll really get bogged down...  Mind you with a good team you can do things very fast, my last film job involved building a 5th scale loco of one of the Mumbai trains , with a team of 4 we built it in five weeks. Ok it didn't need to work as it was fired through a model of the Mumbai railway station( yes we had to build a model of that too, over 20' high) with an air mortar but the really impressive thing about all this is we didn't have a single drawing for either the train or the station. We had to draw up our own by sending someone to Mumbai with a camera and a yardstick to take literally hundreds of photos to scale from. There was little room for era either as these models once shot have to be overlaid with footage of the real train/building. This is perhaps one of the reasons why production companies from all over the world will use an UK crew for miniatures... |

Sounds like you have an interesting job! I once met a model maker in the 70's who was working on the Gerry Anderson set (FAB!). He was making spaceships out of Fairy Liquid bottles!

Haha,,, yes before my time I'm afraid and Jerry Anderson stuff although very clever in it's day is pretty basic. I know some of the original modellers of those days have worked with them and I think they would be the first to agree with me . I've worked on a few puppet productions, last was the recent Diet Coke advert, before that a feature length spoof of James Bond. No washing up bottles there, the third scale car body was made in carbonfibre laid up by a company that produces panels for F1, in fact the same company that I used for the Batman Begins film, they laid up the 1/3rd scale body parts for the Batmobil, I was the buyer on that film, in materials only just for the car I spent close to £250k, my point is this type of work is in a different league completely to the Thunderbird shows from the 60's

I have a very good friend who would agree with you completely Mike, he has a large collection of stuff from the shows plus some new stuff made for adverts etc. There are plans I believe for some new thunderbird stuff although whether that will happen or not is anyones guess. He also is in the process of building new puppets which we often see him working on during lunch times, hes asked me to do the eyes for him as they require a little engineering work in brass. So Mike your not alone in liking Gerry Anderson stuff, my fab was always stingray. Oh btw there's plans afoot to do a new TV series of captain scarlet, I was hoping to be involved around now but production hasn't started yet, rumors are it's some 3/4 years of work so things could be looking up for GA fans.

Ok I have a few more pics and then we are up to date with where I am with the Doncaster build, I'll only show the main stages so I don't bore you too much.... Pic63 Here the counter bracket and flap have been built and attached to the body , there is also 1/4 brass angle added around the top of the lockers Attachments:

Coal scuttle support brackets fitted, they are held temporary in place with hex heads, these need to be changed to round heads when I get some. Attachments:

Pic67 And this picture brings us up to date with the build so far, some will recognise this as the lower coal door that I asked for help with in my other thread. A big thank you to everyone for the help that I received with a special mention for Trevor. Thanks guys Pete Attachments:

You're building one fantastic model there Pete with or without the help of the leprechauns. Your experience and skills acquired in you work really come to the fore. Great stuff! Jim, ps, I have some gnomes in my workshop who would love to come and visit |

Gnomes are welcome, more so if they build my boiler for me overnight, they can give the leprechauns a kick to get the little buggers moving. Mind you it's a hell of a swim for the poor things.... Pete |

Pic68 Just one picture for today, this is the top coal door, started it last night and just finished it, still needs a clean up but otherwise it's ready to be fitted to the body. Next I need to do the hinge blocks for both top and lower doors. I have to say there's a lot of work involved in making these doors, must have been very costly to make the originals which is interesting and perhaps confirms an observation that I made when using the Tornado as reference. The doors on the tornado tender are plain sheets of steel, also she has no coping detail around the tender body, ways of saving money perhaps? Mind you this doesn't take anything away from her beauty... Edit: just realised I haven't machined the two slots yet, similar to the single slot seen in the lower door,, this can wait till tomorrow now, it's been a long day... Pete Attachments:

Pic69 With the forgotten slots for the top door now machined ( must be my age) I moved on to the hinge blocks and then fitted the doors to see how it looks. I still have to finish shaping the blocks and need to fabricate the latches. I now understand how the lower door is held closed and the counter flap too thanks to the help received from some of you guys. I need to do a little more research to see how the upper door latch works , getting there. Pete Attachments:
