sej Posted March 9, 2013 Share Posted March 9, 2013 Hi, I'm going to scratch-build an LSWR 4-4-0 tender loco in 2mm Finescale and am wondering what readily available bits and pieces people would recommend for the motor/gearbox drive system? I would like it to have the motor in the tender with a UJ coupled to a gearbox in the loco. Regards Simon Link to post Share on other sites More sharing options...
2mm Andy Posted March 23, 2013 Share Posted March 23, 2013 Simon, I've just realised that no-one has responded to your question. I'd recommend that you get hold of the 2mm SA publication on split frame chassis design, and also the 2mm magazine back-numbers CD. Both contain useful info/articles on the subject of UJs and gearboxes. There is also a download in the members area of the 2mm website on building a Great Eastern 0-6-0 tender loco which is well worth a look.

Armchair Modeller Posted March 23, 2013 Share Posted March 23, 2013 The instruction sheets for the 2mm etched replacement chassis for various locos may give you a few ideas https://docs.google.com/file/d/0B7V9MIj3SLTgYTZkZGM1NDEtZTQxNi00ZGM5LTg5ZDUtMGU3NGY0NWI0MDM1/edit?pli=1 and the associated drawings sheet http://2mm.org.uk/products/instruction_sheets/chassis_combined_drwgs.pdf Assuming you are a member of the 2mm Scale Association, their Yahoo group may be a better place to ask this question. It is likely that everyone will have a slightly different answer Area group blog sites like http://neag.2mm.org.uk/ often have photos and descriptions of loco builds, but need time to trawl through. Here are Tony Simms D49 construction articles http://neag.2mm.org.uk/search/label/D49 Link to post Share on other sites More sharing options...

If it's still of interest I have a friend who's building a 2mm finescale LSWR T9 4-4-0 with both the 8 wheeled 'Watercart' and standard 6 wheeled tender. If you contact me offline with a message if you're still interested I will ask him if I could give you his email address. He doesn't post here anymore but I let him know whenever i see him if I see anything that might really be of interest. Oli Link to post Share on other sites More sharing options...

RMweb Premium Nig H Posted March 26, 2013 RMweb Premium Share Posted March 26, 2013 Hello Simon, I built a Midland 4-4-0 many years ago using an arrangement similar to that shown in this photo. The chassis at the front is the one I refer to. A 38:1 worm on the driver, no spur gears. You will need to scheme an arrangement out, assuming say a 10mm diameter can motor in the tender, then see how the gearing can be fitted in. It helps if you have a cad package, but I did the 4-4-0 with pencil and paper. There are some pics on this thread which may also give you some ideas. http://www.rmweb.co.uk/community/index.php?/topic/66582-modelling-a-2mm-finescale-duchess/ If you have more queries, do ask.

RMweb Premium Izzy Posted March 26, 2013 RMweb Premium Share Posted March 26, 2013 N brass are now making ball & socket UJ drive bits. They are made to suit 1.5mm shafting but look 'convertable' to match your needs. I haven't tried them yet, but intend to in a Bo-Bo diesel chassis that is 'in progress'.

Crosland Posted May 20, 2014 Share Posted May 20, 2014 N brass are now making ball & socket UJ drive bits. They are made to suit 1.5mm shafting but look 'convertable' to match your needs. I haven't tried them yet, but intend to in a Bo-Bo diesel chassis that is 'in progress'. Izzy Has anyone used these? I found that the ball & socket parts were too tight a fit meaning that the UJ shaft was "biased" and wanted to spring to one side, rather than lying in line with the motor and worm. Multiply by two for each end and I was worried about the friction this was going to cause. I didn't fancy trying to fettle the plastic parts and ended up making my own.
