Courtney Posted December 6, 2009 Share Posted December 6, 2009 Hello - I'm just in the process of adding extra weight to an older model (Hornby class 25) but do you have to take into account the balance of the model? I've filled the fuel tank with lead shot but it it advisable to balance out the motor with equivalent weight such that the 'axel loading' is equal? Changing the subject slightly - is the cab configuration totally wrong (not that you see much of it!) Thanks Link to post Share on other sites More sharing options...
Kenton Posted December 6, 2009 Share Posted December 6, 2009 Always better to try to balance the weight distribution about a center of gravity that makes sense for the wheel arrangement. Link to post Share on other sites More sharing options...
Miss Prism Posted December 6, 2009 Share Posted December 6, 2009 Is this Hornby 25 driven on one bogie only? Link to post Share on other sites More sharing options...
Courtney Posted December 6, 2009 Author Share Posted December 6, 2009 Is this Hornby 25 driven on one bogie only? It is indeed only single motored as it's only for use on a shunty plank - it has had traction wheels replaced and extra pickups fitted Link to post Share on other sites More sharing options...
Anglian Posted December 6, 2009 Share Posted December 6, 2009 I thought this was going to be about wheel balancing and I was about to think, now that is dedication to detail for you??¦ Link to post Share on other sites More sharing options...
Miss Prism Posted December 6, 2009 Share Posted December 6, 2009 Yes it does help if the two axles of a drive bogie are equally weighted. It's a moot point whether you need to add anything to a shunty plank loco, because the traction will be sufficient. Adding weight to the unpowered bogie will improve the stability of the loco as a whole, but you will be dragging around more dead weight. Again, unlikely to be an issue for a shunty plank loco.
