Ruston Posted July 25, 2019 Share Posted July 25, 2019 (edited) Robert Stephenson long-boiler 4-4-0ST. Scale: 4mm/OO This is one that I've been meaning to do for a while now but it was always way down the list of things do do but as I have some Gibson driving wheels of the correct diameter lying around I thought I'd make a start. Also, before I start, I'm wondering if anyone has any more photos and information on the protoype? All I have is the drawing from Mike Sharman's book of drawings of the locomotives of Boulton's Siding and the photos, posted below. The two engines could even be the same one but at different locations as the cab appears to be wooden and not original equipment and it looks the same on both. The first one I think is at Peckfield Colliery, near Leeds and the name Emyln on the second I assume is somewhere in South Wales, possibly also a colliery.

Ruston Posted July 26, 2019 Author Share Posted July 26, 2019 I had done most of the drawings a few weeks ago but I couldn't sleep because of the hot weather, last night, so I did more and have now converted them into patterns for use with my pantograph engraver. This is everything up to the running plate, except for the steps, which I have only just remembered right now as I type. Materials will be 10 thou and 20 thou. cartridge brass and 40 thou. and 60 thou. engraving brass. I'll cut that lot, tomorrow, and if all goes well I'll get it soldered together. 5 1 Link to post Share on other sites More sharing options...

Ruston Posted July 27, 2019 Author Share Posted July 27, 2019 I haven't got as far as I'd hoped. The first part, freshly cut and still full of swarf, oil, and burrs. 8 1 Link to post Share on other sites More sharing options...
Ruston Posted July 28, 2019 Author Share Posted July 28, 2019 The frames and running plate are built up now. One splasher arc remains to be fitted as I lost it somewhere on the floor and it's easier and quicker to make a new one than it is to search for it. The splasher tops will be pieces of shim, roughly cut, soldered on and then filed down in place. Apart from that there are only the steps to add for now. The brake gear comes later. The wheels are temporary and are old K's wheels from their Hudswell Clarke kit. I was wrong about having the wheels in stock for this project and so I'll have to send off to Gibsons for some. The bogie wheels could be a problem as I need 8mm dia. wheels. 10 6 Link to post Share on other sites More sharing options...
johnarcher Posted July 28, 2019 Share Posted July 28, 2019 That's looking very interesting. I don't know about 8mm wheels for 00/EM/P4 (not sure which this is), but if you're stuck they are produced for 00n3 use (would need new axles of course), Dundas do them ( https://www.dundasmodels.co.uk/webstore/index.php/hikashop-menu-for-module-108/category/542-dundas-models-00n3-wheels-bearings ) I thnk Branchlines do too. 1 Link to post Share on other sites More sharing options...
sej Posted July 29, 2019 Share Posted July 29, 2019 There are some really fascinating scratch-builds going on at the moment; looking forward to seeing how you progress and very interested in the pantograph engraving. Could you show us it in action? Cheers Simon 1 Link to post Share on other sites More sharing options...

Ruston Posted July 29, 2019 Author Share Posted July 29, 2019 I'll take some pictures when next cut some parts. I have to make the patterns for the bodywork and steps yet but here's the machine itself. It's a Taylor Hobson Model D. I don't know how old it is but I'd guess 1960s. The more modern ones look to be more squared-off. Of course engraving machines look completely different today and are computer-driven but this is proper old school and all manual. It's very heavy and all cast iron and steel. It had to be lifed off a trailer using a block and tackle, suspended from the roof beams of the garage, and then rolled on socket set extension bars to get it in place. 14 1 Link to post Share on other sites More sharing options...

I have a model D also and it gets a lot of use in cutting out mostly 7 mm scale loco parts. It is very satisfying steering the stylus round a pattern and watching a loco kit appear! Mine lives in my workshop, which is next to the dining room so warm and dry. I assume your slides and tables are greased from the picture. You can still pick up a good example at quite modest cost but watch out for damaged pantograph arms which can be expensive to repair or replace. The main body is very heavy and rigid but careless handling with badly placed slings can wreck the quite delecate working parts. Ian Link to post Share on other sites More sharing options...
Ruston Posted July 30, 2019 Author Share Posted July 30, 2019 Does anyone know which buffers that are available commercially are the nearest match to those in the drawing? And is there anything that's also available that looks like the steam dome? I'd rather not make that dome from scratch if I can help it. Link to post Share on other sites More sharing options...
Ruston Posted July 30, 2019 Author Share Posted July 30, 2019 (edited) The beginings of the boiler. I sawed a length of brass tube and then filed flats on the ends, which allow it to sit on plinths made from 40thou. engraving brass. These are tapped 12BA so that the boiler/tank can be made as a seperate assembly. I'll cut the hole in the bottom (and the top if needs be) for the gearbox once I decide which gearbox to use. It's probably going to be a High Level 'Slimliner' so more of the boiler can be kept, rather than cutting a wide section out. I may use another type and conceal the gearbox in the firebox but I want to leave the firebox free to get as much weight in as possible. I'm trying to make it so most of the weight is over the driving wheels. Edited July 30, 2019 by Ruston 6 1 Link to post Share on other sites More sharing options...
PatB Posted July 31, 2019 Share Posted July 31, 2019 he basic buffer shape, with the large diameter shank, makes me think of the much more modern BR oleo designs, so maybe look at something like those, possibly with the judicious application of a file. As for the dome, that looks pretty big. Perhaps think in terms of a 7mm component of some kind. Link to post Share on other sites More sharing options...

Gibson 4915 are a fairly close match. 1 Link to post Share on other sites More sharing options...
Ruston Posted August 20, 2019 Author Share Posted August 20, 2019 I have made the patterns for the tank and smokebox front plate, plus the cabside and rear plates. I've also done one for the steps that I forgot to do last time. The plain circular pattern will fit inside the boiler tube and serves to centre the smokebox front plate and door. The red marker pen lines are alongside styrene strips that are stuck on the patterns and remind me which side to put the stylus on. This method cuts down on the amount of individual patterns I need to make and so saves time and materials. For example, the top RH rectangle is the tank top but by running the stylus along the red line, and by putting holes in where marked with a circle, I can make the tank sides too. 4 1 1 Link to post Share on other sites More sharing options...
Ruston Posted August 20, 2019 Author Share Posted August 20, 2019 It's very difficult to photograph shiny brass but here are the parts, ready to be assembled into a saddle tank. They aren't bent, it's just a trick of the light or camera lens! 9 1 Link to post Share on other sites More sharing options...
Ruston Posted August 21, 2019 Author Share Posted August 21, 2019 I nearly wasn't here to make this post. My desk lamp on the workbench melted its cable insulation on the earthing bolt of the steel plate on my resistance soldering unit, which can get quite hot and so the plate had 240 volts in it. I don't know how long it's been like that but probably since I last used it when putting the frames together on this loco. I only found this out when touching the plate and reaching to the socket to switch my soldering iron on at the wall. It was like being in a Tom and Jerry cartoon or something - only not quite so funny. I'll be drilling a hole in the bench and routing the lamp cable underneath and away from anything likely to melt it... The tank built up and the front plate of the smokebox. Not fixed yet and simply sat on for the photo. 7 1 2 6 Link to post Share on other sites More sharing options...
Popular Post Ruston Posted October 14, 2019 Author Popular Post Share Posted October 14, 2019 Progress has been slow but I've done a a little more. I've made the smokebox door but haven't added the hinges yet. The splashers are in and some cast brass springs have been fitted. The saddle tank now has its beading soldered on around the top and some Alan Gibson buffers have been fitted. At the other end, I have made and fitted the firebox end. I'll wrap the firebox with plastikard and will also make the detailed backhead from plastikard and other styrene bits. I've just noticed that I've sat the tank on the wrong way around. I'm going to try and have the tank fixed to the boiler by a screw through the filler hole and the filler lid a push-fit into the hole. 18 3 Link to post Share on other sites More sharing options...
Ruston Posted October 16, 2019 Author Share Posted October 16, 2019 I've made a start on the bogie, which isn't properly mounted yet. The motor and gearbox are in and the wheels are on. It's been tested but with crocodile clips to the motor wires as there are no pickups fitted yet. 9 1 2 Link to post Share on other sites More sharing options...
Armchair Modeller Posted October 16, 2019 Share Posted October 16, 2019 Just curious, but are you keeping the front driving wheels flanged, or is that just your temporary wheels again? Also, which wheels are you using for the bogie, please? Link to post Share on other sites More sharing options...

Also, which wheels are you using for the bogie, please? All the wheels shown are the proper wheels and all are flanged. They are Alan Gibson 14mm Manning Wardle wheels as these are the nearest I could get in appearance to the RS wheels. The bogie uses 8mm wheels from a Roy C. Link O-14 skip chassis with the centres opened to enable them to fit onto a standard OO wagon axle for pinpoint bearings. 1 Link to post Share on other sites More sharing options...
