Killian keane Posted August 17, 2017 Share Posted August 17, 2017 I recently aquired a part built Ks kit for a broad gauge rover class loco, and how to motorise this beast eludes me, removing the rear six wheels allows only a small gap of insufficient size to fit any suitable sized motor, I feel I'm going to have to dissasemble the bodywork to some degree, has anybody else experience in motorising this kit?

RMweb Gold The Johnster Posted August 17, 2017 RMweb Gold Share Posted August 17, 2017 Even I can see the argument for tender drive in this case! Or possibly motor in tender with shaft drive to driving axle. Link to post Share on other sites More sharing options...
Killian keane Posted August 17, 2017 Author Share Posted August 17, 2017 Even I can see the argument for tender drive in this case! Or possibly motor in tender with shaft drive to driving axle.The space inside the tender is plenty wide, but the depression for the coal takes up half of the length, whereas the loco boiler has plenty of space for a decent motor with a flywheel, besides, I don't generally beleive in tender drive Link to post Share on other sites More sharing options...
RMweb Gold The Johnster Posted August 17, 2017 RMweb Gold Share Posted August 17, 2017 Nor me. How about mounting the motor facing backwards in the boiler and drive down through the bottom of the firebox, then back forward (can you write back forward with the words together like that) to a gear on the driving axle; by that time the drive shaft might be underneath the axle! You would need 2 separate 90 degree drive joints, and I am only offering the idea as a suggestion, not claiming it to be a practical solution. Some sort of belt or rubber band system might work as well. I'm getting desparate now; please do not attempt a working model of Harrison's 'Hurricane' as the real one didn't work either and that would be a serious challenge to hide the motor and drive on...

RMweb Gold The Johnster Posted August 17, 2017 RMweb Gold Share Posted August 17, 2017 It has just occurred to me that you might, given the size of the beast, be able to vertically mount a motor in the firebox and drive the trailing axle; how much traction this would give you is a moot point.

Killian keane Posted August 17, 2017 Author Share Posted August 17, 2017 Driving the rear axle isn't a possibility as its on a bogie, as is the wheel set in front of the drivers (but not the front set bizarrely), the gap is 12mm x 26mm, as for hurricane and Thunderer, must resist temptation!

34theletterbetweenB&D Posted August 17, 2017 Share Posted August 17, 2017 (edited) There are kit gearboxes that will enable the motor to lie horizontally in the boiler, take a gear train vertically down through the firebox, and then turn the drive forward to engage the driving wheel axle. Scheming it out within the constraints of the K's components, especially the part assembled body, will be the challenge. Apply to kit gearbox suppliers for their poop sheets to work up a layout (Branchlines, Comet, High Level, come to mind). Edited to add: Having seen the photo, you will need to cut a fair size access through all that whitemetal! I take it from the description of the two wheelsets either side of the driver being in trucks, that it has a truly original 1-1-1-1 configuration, and is effectively a rigid four wheeler running on the front bogie wheels and the drivers, with the two other wheelsets just along for the ride? If so, then to use the suggested scheme will probably require an alternative plan for provision of the trailing wheelset pivot.

RMweb Gold The Johnster Posted August 18, 2017 RMweb Gold Share Posted August 18, 2017 It might be easier to scratchbuild using some of the kit parts than to have to cut away such a mass of whitemetal. Link to post Share on other sites More sharing options...
bgman Posted August 18, 2017 Share Posted August 18, 2017 Motorising the Rover ( loco ) has been done in the past, but a better solution is to use the tender motorising kit which was produced by Kay Butler owner of KEYKITS. I'm not certain if it is available through the Broad Gauge Society but may well be through KEYKITS. I helped with the concept and trial of this many years ago with Kay and successfully motorised the tender which was chipped with a Lenz decoder about 10 years ago. Due to the weight of the locomotive it holds the track and is pushed by the tender without any problems. Hope this of some use.

bgman Posted August 18, 2017 Share Posted August 18, 2017 Having looked at the KEYKITS site after posting the above it would appear that all of the "kits and components " are marketed through the BGS and the Rover comes as a complete kit. Sorry if I have mis-lead anyone with this. 1 Link to post Share on other sites More sharing options...
