Flying Scotsman as Preserved

My last project was making Bittern Double Tender. My new project is going to be as above. To date I have bought a FS body off Ebay. I have on order a set of German style smoke deflectors which are a brass etch, so it should not be too much of an exercise to (ahem!) execute!

I have included a photo of FS which I am going to reproduce.

Some things shouldn't be there!

The other day I replaced the piston and gland o-rings on my DDE. An easy job and well worth doing. However I found more than I bargained for....

Not only was there the o-rings, but on one side was this extra thing! It was a metal ring within the gland nut. Amazing what some people do, see photo, the metal ring is the one on the right.

Live Steam Endurance Test

I have read in peoples testaments of running their locos for around 30 minutes, and I got to think whether they could go longer on one steaming. Try 45 minutes!! Here's how:

Firstly I will describe my layout. It is a double track main line with R4 outside and R3 inside settrack curves set in a shed 6x3 metres. The outside track length is 15.412 metres long.

So the 'how' is easy. Isolate part of the circuit from electrical power. I have two sections of isolation, one being the access bridge to the room, 914mm and the other is between sets of points which is 3.27 metres long.

The train was Mallard with 8 Backmann MK1 Blood and Custards all with metal wheels and to minimise rolling friction I lubricated each axle.

I firstly ran Mallard for a few laps to warm her up, then after cooling for a while…

Another method to reduce heater power and extend running time is described here:

A4 cylinder support stuck

Hi all,


I've started stripping my Mallard down as per the advice on here, and I'm following the video tutorial, however the cylinder support just seems to pop off when you remove the valve gear in the maintenance video.

Mines stuck fast. Am I doing something wrong?

The plastic support is held in place by a single slotted screw. If you have removed the screw and it is still stuck then it is only old oil holding it in place, acting like a bit like a glue. Tap or prize it free.

Prototype Loco Display Stand

History

Many of us are fortunate enough to have more than one loco or more than one type of loco and would like to have more, but not necessarily the same again so the club decided to offer some limited-edition locos.  These are not new locomotive builds, but a change to those that are already out there intended to enhance your collection and build value over time.


​In 2018 the club launched a choice of four limited edition A4 loco in experimental purple, followed in 2019 with a choice of nine LNER green versions.


To display the locos Nick Beard designed and made a rotating turntable to fit on his camera tripod and this solution worked well for us for five years.

What are you doing this weekend???

Just two days to go!

It’s the Severn Vally Railway for us and the roadshow this coming weekend as it’s their model railway weekend.

We will be located in the Engine Shed at Highley with a full shop and usual facilities! Come for a play and a natter, you know you want to!!! …. And the heritage railway needs all the support it can get!!

Hi all from York

Hi everyone, and thanks for approving me Chris! I've finally bit the bullet after all these years and purchased a Mallard kit (sans accessories but I can get syringes anywhere) which is completly unused and in great condition. Looking forward to getting this thing up and running. An avid fan of live steam for many years, but cant quite commit to 5" guage like my dad

A3 Valve/Regulator Drive problem

Dear everybody,

I'm the owner of A3 Flying Scotsman leave steam (used) and faced the following issue. The Regulator Drive Rod has been somehow broken and "fixed" by soldering (see pictures).

Now the regulator seems working, servo and gears rotating, even the drive rod moving. But the steam valve not working, no steam flow and, of course, no train movement. Control LEDs at certain switch from green to red, then both light at the same time, which I also think is abnormal.

I would be grateful for any ideas on how to fix this.

Dear Chris (and hello to everybody!), first many thanks for your very clear instructions which is really of big help! I had to interrupt to have some free time and also wait for proper compressor.

I dismantled everything in front from steam regulator to pistons, washed with alchohol and checked the airflow, which was good. I didn't touch the cylinders/pistons. I also replaced the regulator drive rod, put the regulator to fully front position (means open fully).

What I got - when I deliver air directly to the regulator hole (video in this post) the mechanism starts moving, not very fast, but moving.

I even did this through the regulator valve (next post).

But when I assembled regulator, superheater back and provided airflow normal way (with adapter I got from OOLS) the mechanism just tried to move and then stuck (last video)

I have 2 ideas:

  1. Some air/steam leakage from the superheater (but why)

  2. Mechanism rotation is still difficult because of wheels and timing shaft contamination.

    I would be grateful for further opinios and advices

    Dmitry
