Excellent job Julian, those blades are a really good fit. I have found Masokits stretchers a bit frustrating, I do one that comes out just right then the next will play up and not solder together properly but you seem to have cracked it.

I also saw that the 4mm answer was not twice the 2mm answer. I know why, and the reason is clearly visible if you look at the ratios, but it looks potentially to be a bit ambiguous to me. This is a problem started by Peco!, 2mm scale should not be 1:148 but 1:152.4. 1:148 was created by Peco (IIRC)...

Someone has been confusing you, that reliable information was wrong. :) The 6 in B6 stands for a crossing angle of 1:6. Similarly B7 and B8 have crossing angles of 1:7 and 1:8 respectively. And so on..... The B indicates the design of the switch blades which run from A as the shortest up to G and be...

Since you have enough current leaking though for you to see the LED lighting up, and it cannot be induced when using a battery there has to be a resistance path much lower than it should be. I would estimate somewhere between 4700 ohms and 20000 ohms which should be easily measurable with a multimet...

In the beginning, which you will find in the P4 Manual and issues of Prototype See history section of this website) there were two recommended widths depending on side play wanted and I think the spacers were 15 mm and 15.5 mm with 0.5 mm thick frames. Since then kit designers have done their thing ...

I agree with Tony on this. Its safe enough to just ignore it.

He does leaflets on his various ranges for a few pence so you could use one phone call to ask him to send you a set. In normal times we pick these up at exhibitions.

but in practice they could only do that when the loco was working hard for a sustained period of time. When the loco was not working, live steam had to be used for both injectors.

Of course the loco does not need much water when its not working.

By the way, just to show my complete ignorance of electricity, I had gained the impression that current flows from the negative terminal of the power supply to the positive terminal, but should that be the other way round? Maybe it doesn't matter so long as the Positive terminal is correctly identi...

Could you temporarily substitute the H&M supply with a 9V PP3 battery and see if you get the same effect?
There is possibly some capacitative leakage through the switch wiring which should not occur with a smooth DC like from a battery.

If you post thr circuit here then maybe we can see something.

Applying superelevation to plain double track would normally be by raising each outer rail. However where there has to be connection between the two tracks then all 4 rails need to be in the same plane which would use a huge amount of ballast if just done by packing in more ballast so usually the un...

Philip, If cutting the tread by running a tool along it then you are limited to turning the headstock to create a taper. But that is not the case with a form tool as you feed it in directly with the cross slide so can angle the tool post to cut the taper. But maybe not with the Teichmann tool that d...

As for all non-members.

I'm interested. Side note, I saw an article somewhere. The author made a form tool by turning a disk, then cutting a notch in (with suitable rake). My point is, that tool was able to be resharpened many times. Not sure of the design being contemplated, and I'll buy it either way, just offering a co...

The 3 finger bearing carriers usually clamp onto the wire pretty tight, are you sure its meant to be CSB and not 3 individual springs per side?

I haven't tried the 6 wheel bogies but generally CSBs need to be able to move as the suspension moves. soldering or glueing to the bearing carriers will interfere with the action. Usually there are end stops in the frame so the wire can't come out when all assembled, sometimes the wire needs a 90 de...

I thought I heard 6 wires, which I would take to be 2 DCC and 4 CANBUS. Did I hear that you are developing a CANBUS system? I use the MERG CBUS which is a fully developed CANBUS system all available as kits.

Original link asked me to register but after that seemed to want me to create a live stream.
Anyway, got it through Danny's link but it says that live chat is disabled.

I think it unlikely that the train would run with a fitted head, more likely the fitted wagons would run wirh brake pipes unconnected and the marshalling order just be based on the shunting requirements.

Thanks Keith for that useful tip. Regarding the subject of key direction in general, is it right that rails generally creep in the direction of travel, so keys are driven in against it? I.e. generally from the left. In the case of a single line or siding is there a custom/practice? See https://www....

The code 75 is the height of the rail, not the head width. The width does vary between makes, largely dependent, I think on the age of the die. I suppose the height will similarly vary as the tool ages, but should not get anywhere near code 85. A prototype 95lb bull head rail when new is 145.26 mm h...

Anyway ... beyond some experimentation I need to progress the layout design such that I can get some baseboards up and running. Still keen to see what might be possible using Styrofoam ;) Rod Cameron has expanded on his Scalefour News article with a topic on RMweb, a search for Lewes should find it.

I fitted my Masokits ones after laying the track, Wasn't particulary hard. I don't think fitting them to loose turnouts would be any easier.
