Raffles Posted September 11, 2012 Author Share Posted September 11, 2012 (edited) You could be in luck Jon, as we have taken the louvres off of 47105. We have them in store so I may be able to get some shots next time I'm up at the railway. Tom - I haven't forgotten about those bits of '376 if you still want them measured.

Pugsley Posted September 11, 2012 Share Posted September 11, 2012 I think he's saying that the wheel diameter is a set figure (3ft9ins, or 3.75ft if you prefer). Using this, you can assume that the wheel in the photo is that size and find out a scale from there. Then, use that scale to measure the bufferbeam fittings in the photo and scale them up. Yep, that was exactly what I meant 8) 1 Link to post Share on other sites More sharing options...

eddieprice Posted December 23, 2012 Share Posted December 23, 2012 I am new to this forum, but it is just what I am looking for. I have just started to collect information on the Class 47 in order to scratch build one in 10mm scale. There are lots of images of 47s on the web, but generally they are low resolution jpegs. I managed to find some side and front elevation diagrams, but again they are low resolution jppeg. They have given me the general body outline and the wheel bogies. Some of the images from Raffles and Tomstaf in this thread will help me with the bogies. It would be nice to have a complete side view of one of the bogies. Raffles submitted one in June 2011 of part of the bogie and Tomstaf produced one in July. Any chance that one of you might have a detail image of a complete bogie, or at least of the centre pair of wheels. I would like to see how the central axle box is attached to the suspension beams. Some of the other images will be a great help - the front of the cab, the interior of the cab, the front buffer beam and the upper circular vent and the louvres. Does anyone know of a source a good quality outline diagrams? Eddie Price Link to post Share on other sites More sharing options...
tomstaf Posted December 23, 2012 Share Posted December 23, 2012 Hi Eddie, Sounds interesting. I've never come across a set of complete diagrams. I've got this shot of a bogie - is it what you're after? Cheers Tom 1 Link to post Share on other sites More sharing options...

eddieprice Posted January 10, 2013 Share Posted January 10, 2013 I am in the process of preparing some drawings for a class 47 in order to make a gauge 1 model. I have prepared general arrangement drawings of the bogies and am now trying to add some detail. I have been trying to work out how the brakes work. I don't want to make working brakes, but I would like to show the brake linkages. I think I can identify the brake cylinder and the levers that operates the brake shoes, but I haven't been able to find a photograph that shows how the hand brake operates. There appear to be two levers, 1 and 2, that emerge from the bottom of the hand brake housing, but what happens underneath the housing? One possibility is that there is an arm that rotates and that the two levers, 1 and 2, are attached to either end of the arm so that when the arm rotates the levers are pulled and they operate the brake shoes. The slot that can be seen in Lever 2 would allow the brake cylinder to operate normally. The hand brake would pull the brake cylinder lever to the left and so operate the brake shoes. Is this sort of detail on the Bachman or Hornby models? The photograph comes from www.4701project.co.uk Eddie Price Link to post Share on other sites More sharing options...
surfsup Posted January 16, 2013 Share Posted January 16, 2013 (edited) Here's a couple of images ive taken over the past few years. Most of the images were taken from during my time working down in Eastleigh - and ones i can find on my current computer. Be careful though, they are the original size. Can resized if requested.

surfsup Posted January 16, 2013 Share Posted January 16, 2013 Not completely 47s, but it's still the same shell. 1 Link to post Share on other sites More sharing options...
Jon020 Posted January 16, 2013 Share Posted January 16, 2013 (edited) Very nice photos those. I don't suppose anyone can provide, or point to a source of photos of details of fuel tanks and battle boxes of original generators... such as found on 47414 or the like... period BR blue mid 70s is what I'm interested in so that I can "fix" those of my Bachmann model.

eddieprice Posted January 18, 2013 Share Posted January 18, 2013 Some great photographs. I have made a start on making the bogies and there is a lot of detail in some of your photos. Also a good side elevation of the complete loco. Most photos are taken 3/4 view and are impossible to scale. Great Eddie Price Link to post Share on other sites More sharing options...
eddieprice Posted January 18, 2013 Share Posted January 18, 2013 Been playing around with Google Sketchup and this is an image of the bogie that I hope to make. Its a 2D image rather than the 3D one produced within Sketchup. But the 3D file is about 5Mb and you need a viewer to see it Link to post Share on other sites More sharing options...
Jon020 Posted January 18, 2013 Share Posted January 18, 2013 Well, these are the ones I've knocked up after a fair bit of work. Posted in the gallery already, but possibly worth copying here. As I said previously, now I've got the tanks to correct. I'm doing an early generator (2nd batch of ECML machines), e.g. 47414 or the like (but not 47401-47410). ... so I need some help for pointers to photos of tanks details so I can work on the item provided by Bachmann. Nice 3D modelling by the way - something I've not even attempted really - I'm a techno luddite... but it's nice to admire other's work. Jon 7 Link to post Share on other sites More sharing options...
tomstaf Posted January 18, 2013 Share Posted January 18, 2013 Hi, Anyone know or able to get the diameter of the spring linked to the brake gear on each corner of the bogie please? Cheers Tom Link to post Share on other sites More sharing options...
eddieprice Posted January 19, 2013 Share Posted January 19, 2013 Beautiful modelling Jon. Gives me something to aim for. As to the spring Tom, I would say it's 5" in diameter by 20" long, based on a photograph published by you actually last July. I imported the photo into my CAD program. I then added a circle to match the wheel, which should be 3' 9" in diameter. From this I scaled the spring. Link to post Share on other sites More sharing options...

eddieprice Posted January 20, 2013 Share Posted January 20, 2013 Hello Jon. I wonder if I could beg some information about your model. I am interested in the springs on the bogie. I can understand the outer pair, but am not clear of where the bottom ends of the second inner pair attach. I assume the tops are attached to, what I think is called the spider. You can see it in one of my photos above. It houses the bearing that connects the bogie to the body work. It looks as though the bottom end may be attached to, what I call, the supension arms that are connected to the axle boxes??? I have started to machine brass for the bogie. I have machined the wheels - all one dozen!!! Eddie Price Link to post Share on other sites More sharing options...
eddieprice Posted January 21, 2013 Share Posted January 21, 2013 I think I have worked out how the inner set of springs are attached to the bogie and the spider, and so on with the machining. Link to post Share on other sites More sharing options...
eddieprice Posted January 22, 2013 Share Posted January 22, 2013 I am still looking for class47 detailed shots to help with building a gauge 1 version. I am trying to puzzle out what keeps the axle boxes in place. Here is an image. I know there is a suspension bar beneath the axle box. Is this what holds the box in place? The box can move up and down. Is there anything to prevent the box moving in and out, apart from the suspension bar fitting in a slot at the bottom of the box? I have built a couple of steam locos and the sides of the axle boxes are slotted so that they can only move up and down in the horns. Link to post Share on other sites More sharing options...
Pugsley Posted January 22, 2013 Share Posted January 22, 2013 The side pieces wrap round the rear of the bogie frame, which you can see if you look carefully in the top left of the picture, this is what checks the lateral motion. Also, the bottom plate does keep the axlebox from dropping out of the frame, again you can see where the two triangular protrusions would contact that bracket if it were to drop far enough. It's a slightly beefier version of the method employed by air braked wagons. The 'suspension bar' you refer to is called an equalising beam, it divides the load between the two axles and helps smooth track irregularities.
