Sharman Wheels M282

Does anyone have these Sharman wheels in P4? This is for a Caledonian Wemyss Bay Tank loco. The wheels are scale 5' 8", 20 spoke, crank on spoke, 26" crank throw. Similar but not quite right wheels readily available from Gibson, Ultrascale, Exactoscale, but the Sharmans should be more exac...

Re: Bachmann Cattle Wagons

Thanks Russ for that advice. Small detail inaccuracies don't worry me overmuch but basic dimensions do. Details can be corrected more easily than for example the basic dimensional error of the Cattle Wagon. I am afraid I'm rather heathen, the brakes of wagons not quite lining up with wheel treads - ...

Re: Bachmann Cattle Wagons

Thanks all. It's a shame - it seems that the recent Scalefour News article on today's relatively easily obtained information doesn't quite apply to the critical area of drawings etc - apart from our own exchanges...? Well, here's asking - I have a few of Bachmann's mogo van, and conflat, and a BR Ma...

Re my previous post - I mean, before purchasing ANY ready to run stock. Sorry - this may sound a rather basic question!

Re: Bachmann Cattle Wagons

Thanks gentlemen for your help.

Before purchasing in future how can I check up on dimensions? Is there an online source of information or drawings?

Re: Bachmann Cattle Wagons

Thanks. Sorry to misquote you Martin. Brain not properly engaged. I meant, the body has got to be made under its length for strict accuracy. What I am wondering is, could that be a reasonably straightforward operation with a cut in one or two places, and if so, where? The fact that the wheelbase is ...

Bachmann Cattle Wagons

Previously it has been stated by Martin Goodall that these wagons are underlength by a scale foot. Has anyone been bothered enough by this to be able to say where the inaccuracy is, and/or whether it is remediable?

Re: "West of Scotland Group's "Starters" Build a loco part 2

Hi Allan - As a kind of aside on the preparation for painting: on my last modelling attempt, the Q1 you've referred to, for the first time I used the chemical blackening stuff from C&L on the wheels and all the chassis that was reachable, before cleaning in Vim equivalent and water and then pain...

Re: Basic tool set for P4 modelling

Hi - I cant see this in suggestions made so far: when I started I had 2 soldering irons, one at 18W and one 25W. What has been brilliant has been an Antex Energy Regulator: a dimmer-switch type of thing which cost about £20. This gives control on the temperature of the iron, and means I can use just...

Re: Auto Direction Change

A correction to my last post. While the 0-12V DC power from a layout contoller (which controls the loco that you're running in or whatever) is no problem, the 12V DC supply input needed to power the actual electronics is not adequately supplied from another layout controller on full power. It has to...

Auto Direction Change

Sorry if this is naieve question. It's only P4 specific because of the 3ft 6in minimum radius I use. I want to run in and test locos. I've no room for a 7 or 8 foot diameter circle, but it's easy enough to have a metre or two of track with the vehicle running backwards and forwards a few hours at a ...

Re: West of Scotland Group's "Starters" Build a loco project

I have some black deposits on phosphor bronze pickups on my latest loco (Q1). No DCC. Steel wheels. I assumed it was my general lack of cleanliness! - so it's reasssuring to see you mentioning this.

Seemingly it's not only me that has learnt quite a lot from this discussion topic, so I'm glad to have opened an interesting discussion. In the MRJ 130 I referred to as answering my original query there are two pictures of the Bachmann wagon, "before and after". One with original Bachmann ...

Re: Wagon Suspension

Again, thanks for useful ideas. My first step will be to get some sample MJT ones and try out. The article in MRJ 130 that the parallel discussion refers to was just what I needed, and shows one of these wagons close up, and the MJT bearings are very unobtrusive. The article's starting point is the ...

Re: Wagon Suspension

Thanks folks. I ought to clarify - I want to get these wagons up to full P4 operational capability, including shunting. I realize work is involved, it's just how little can I get away with time-wise? Clearly I'll have to add weight, get the buffer height right, maybe change the buffers, get proper c...

I've spent many hours making a freight loco to P4 standards. Now I want to get a train of say 20 coal wagons quickly and cheaply. The rtr offerings from Hornby and Bachmann are good enough for me, all they need is to be given the simplest possible suspension system to prevent them derailing. Can any...
