Red Devil Posted December 16, 2019 Share Posted December 16, 2019 I have several layout builds still ongoing any tram related bits I decided I was going dead rail/lipo battery/radio control for the drives.... So I wanted something compact and low profile.... A few bits of brass, some Nigel Lawton bits and and an 8ft 6in MJT bogie etch and this is where we currently are... Nothing new, but thought it might be of interest, EM gauge for my Sheffield Grimeside build. Only half done but yep it runs 7 4 Link to post Share on other sites More sharing options...
Andy Reichert Posted December 18, 2019 Share Posted December 18, 2019 Depending on how much tension you need in the belts, you might want to use ball bearings to keep the friction low. Are you anticipating including working suspension? The axle slots look oval. Andy Link to post Share on other sites More sharing options...
Andy Reichert Posted December 18, 2019 Share Posted December 18, 2019 PS. Which way is up? Andy Link to post Share on other sites More sharing options...
Red Devil Posted December 18, 2019 Author Share Posted December 18, 2019 Doesn't need ball bearings it's fine as is, it is shown the right way , bearings are fitted in the correct position for me, it allows the fitment of a cast truckside which doesn't show the etched frame, no springing doesn't need it for my usage. Bearing holes aren't oval, they're a figure of 8 to allow cosmetic sides in the correct position in their intended use, I've adapted it to suit me. 1 Link to post Share on other sites More sharing options...
Andy Reichert Posted December 18, 2019 Share Posted December 18, 2019 Thanks. Looking good . I like the double speed reduction implementation. Very slick and compact. Andy 1 Link to post Share on other sites More sharing options...
Red Devil Posted January 19, 2020 Author Share Posted January 19, 2020 Ok we have something running..... I spotted some £3 6mm motors with a planetary gearbox so thought I'd give those a whirl..... It's alive....... Running at full speed on only one axle drive (some imbecile, ahem, lost one of the required pulleys) The planetary gearboxes on these little motors gives an amazing amount of torque, really surprised me how much... Yep..definitely worth continuing with, this has given me a whole host of ideas on how to solve a couple of niggles, 'production' versions will be neater/quicker/better.... Rubbish video,sorry, but it shows how it works..... 3 Link to post Share on other sites More sharing options...

Do you know what the ratio is. andy Ebay , loads of sellers, this one is 1:26, then in my build it has two further reductions, there are some with a greater reduction to set off with but they are longer so possibly a bit wide for 4mm in this style of application https://www.ebay.co.uk/itm/DC-3V-Micro-6mm-Planetary-Gear-Reducer-Motor-Mini-Coreless-Gearbox-Motor-1200RPM/323829018023?hash=item4b65b6ada7:g:BgEAAOSwTAxc4qP5 1 Link to post Share on other sites More sharing options...
Red Devil Posted February 27, 2020 Author Share Posted February 27, 2020 Whilst I was messing about with the geared 6mm motor I thought I'd try a Faller Car System version.... So an Oxford Austin van was hacked about and a test belt drive system fitted....I shoved the OD wheels on to give an idea of RPM at 1.5v..... So seemed okay and the rest is proceeding, Wiking Control wheels (Faller sizes way out). Pattern Faller axle and we're getting closer.... 5 Link to post Share on other sites More sharing options...
