bordercollie Posted October 18, 2020 Share Posted October 18, 2020 I have recently acquired some Mashima motors but I was only able to get 14xx series motors. I have some brass loco kits which suggest using mashima 1224 motors. Has anyone fitted a 1424 with a suitable high level gearbox to Malcolm Mitchell small praire kits. The dimensions of the 1224 and 1424 seem to vary by 1.8 mm in height. It doesn't seem to be a great amount but I am wondering if it is, and will cause a problem when the kits are built. I realise it would be better to build the kits first but it will be a while before I have the confidence to build them. I would like to sure that I can fit the 1424 motors and purchase suitable gearboxes whilst they are still available. Regards Link to post Share on other sites More sharing options...
RexAshton Posted October 18, 2020 Share Posted October 18, 2020 Talk to Chris at High Level kits. I'm sure he'll have a gearbox that will allow you to fit the 14mm Mashima. Link to post Share on other sites More sharing options...
hayfield Posted October 18, 2020 Share Posted October 18, 2020 (edited) Below is the highlevel planner, I have successfully fitted a High Level gearbox between a K's 00 gauge chassis which has brass frames, so fitting a gearbox between an etched chassis even in 00 gauge allows a wider range of gear boxes, just choose one which raises the height above the chassis but below the body. You may find using either a Roadrunner+ or a Loadhauler+ preferable as the extender bracket can be adjusted for height and or clearance. http://www.highlevelkits.co.uk/gearboxplanner.pdf http://www.highlevelkits.co.uk/ Chris does a super range of 12mm coreless motors, which seem cheaper than what some are asking for Mashima's now. The bonus is they are better motors Edited October 18, 2020 by hayfield 1 1 Link to post Share on other sites More sharing options...
RMweb Premium Siberian Snooper Posted October 18, 2020 RMweb Premium Share Posted October 18, 2020 I suspect that the biggest difference between the 1224 motor and 1424 motor will be the revs and Chris at High Level, would be the best person to advise on a suitable gear ratio to provide a realistic running speed. 2 Link to post Share on other sites More sharing options...
RMweb Gold Captain Kernow Posted October 18, 2020 RMweb Gold Share Posted October 18, 2020 I have found the Mashima 1024 a useful and powerful motor. Brian Osborne at Branchlines in Westbury still has some in stock. 1 Link to post Share on other sites More sharing options...
bordercollie Posted October 20, 2020 Author Share Posted October 20, 2020 Hi Thanks for your advice. I had thought of contacting Chris at high level but his website states that he can not enter into discussions on Motor/gearbox combinations for any particular kits. I find his suggestions on the webite very helpful but is obviously exhaustive. I am in Australia so a simple telephone conversation isn't practical. I get the impression from e-mails that he is under a fair bit of pressure due to Covid and getting supplies etc. One suggestion on his website for GWR 43xx was to mount the motor vertically. However, someone I know with a fair bit of experience did not like this configuration. What are peoples thoughts on this? I have a document that suggests different gearboxes for different wheel combinations which gives useful tables Link to post Share on other sites More sharing options...
RMweb Premium Barry O Posted October 20, 2020 RMweb Premium Share Posted October 20, 2020 The gearbox planner is easy to use. Motors can be set up in any angle nowadays .. the lubrication problems seen in the past are not really a problem now. Brush design has greatly improved so I wouldn't worry about the motor angle. Try using thelanner.. Baz Link to post Share on other sites More sharing options...
hayfield Posted October 20, 2020 Share Posted October 20, 2020 A stock reply I would go for either a Roadrunner+ or Loadhauler+ as these can be formed in many ways to squeeze into the space available, I would go for the coreless motor for the quality of kit you are building. Personally I go for the mid to lower range of gears with the small wheels . With your order just explain what you want to achieve and if he would email you if he feels the gear choice is incorrect Link to post Share on other sites More sharing options...
