Re: Comparing Geared motors

I bought the 12v high power version, assuming it would be more powerful. I wonder if the low power versions run better at low revs?? What rating are the generic gearmotors? If they have the same motor revs. and stall current rating as the Pololu high power motor then the different running character...

Re: Comparing Geared motors

As you say, maybe it will improve once it's run in. It is certainly worth trying. Run one in at different speeds, as well as changing direction now and again and see if it improves. I've got a vague memory that the Pololu 25D motors in my big diesel became very free running after the test runs they...

Re: Comparing Geared motors

However, when testing my first chassis with a (c£20GBP) Polulo geared motor, I was disappointed to find that it doesn't seem to want to run at slow speed. It jolts to a start when the voltage is relatively high. I'm currently working on a steam loco build, so my mind is in a different space. Howeve...

Re: A Ruston-ish ....

I think, when Ruston's did produce 3' gauge locos, they were inside-framed. Rustons that were built to other than 2' gauge had extensions welded to the sides of the frames to carry the wider wheelsets. This link to a photo taken by the late Weston Langford shows a later model Ruston that ran on the...

Re: A short 4-wheel wagon

It is obviously an inside bearing arrangement - no idea if such things exist on wagons, but they do on my railway! I could add some fake outside springs and axles boxes if anyone complains. If the NSWGR could use surplus garratt bogies as rail tractor chassis, I can't see why your claypit line coul...

Re: 32mm/45mm railway

so my question is how ridiculous is the idea of a 2foot gauge branchline connecting to a 3 foot gauge railway. I'm not aware of any junctions between 2' and 3' gauge common carrier railways in Ireland, although there may have been industrial 2' gauge railways that connected somewhere to a 3' gauge ...

Re: Loco wheels (and other issues) 7/8th scale

However, the PDF LAT kit (I actually have 2 of these so double the trouble) appears to have a few curious 'issues'. The main one being that the steel wheels (which have plastic centres) come fitted to axles of 3.35 dia as opposed to the 3.175 (1/8th inch) bore of the drive gear supplied, plus they ...

McEwan Pratt went broke before WW1, so their records will be long gone. Baguley bought the remains from the receiver and used th...

The only steeple cab IC locomotives I'm aware of were the two Crossleys used by Dorman-Long on the Sydney Harbour bridge contract. They only vaguely resemble the HGLW model, but there is a photo and drawing in the article in Light Railways #133 on this link. http://media.lrrsa.org.au/kabo133/Light_R...

Re: Time to build a railway...but where?

Little three wheelers possibly wouldn't be suitable for conversion to narrow gauge, but if you feel confident enough, try this for size... It's been done with an Isetta ........

Re: Restoration West Side Lumber Shay 15

Does somebody have any idea how to clean this oily engine in one piece? I'm not sure if I can rebuild it when it is in pieces. The loco doesn't look especially oily, so I assume you just want to degrease the areas that need repainting? Since it is an electric model, you need to avoid the usual meth...

Thanks Graeme, and dudeface. The video link supplied shows the articulation from an end-on view, something not usually filmed.
