Very handy things bench grinders. I freehand sharpened an endmill yesterday - look away purists :D

I've got a wire brush that I attach to the bench drill - very handy too :thumbup:
Best wishes,
Dave

I should be getting my larger chimney back tomorrow along with the saddle tank with the new water connection fitted (here are some photos from my friend who has done the work):

Now this is a narrow gauge chimney!

Chimney base brazed on:

New connection for the injector water feed fitted to the saddle tank:

Fitting the connection:

You can see the new water filter for the injector water feed in the saddle tank:

I did a quick trial fit of the chimney and saddle tank this evening:

Now I can get back on with finishing the injector install and having a trial run before the club track opens up to the public at the end of March.

I also need to think about fitting a cab!

I really like how the engine looks with its new chimney. Much better than its previous appearance. What sort of cab are you thinking of adding? Half-height like a quarry Hunslet, or something with spectacles?

Thanks Keith, I am pleased with how the loco is coming along and the experience I am gaining.

Cab wise, undecided so far. The new chimney allows for a large enclosed cab to be fitted, however, as I am going to have to build this myself the simpler option is an open cab with a small plate to mount the whistle onto (I like what Chris Bird has done with his Roundhouse 7/8ths locos):

Making progress with the steam injector install:



The first part of the video is testing the newly installed water feed for the new steam injector and then the final part is the loco running and testing the whistle which has been moved under the boiler as the steam injector takes the space where the whistle was originally installed.

Very happy with the injector, however, I have a few steam leaks to attend to before I can run the loco at the club track again.

Whistle moved under the boiler until I have a cab for it to be bolted onto:

IMG_20200315_160039-01.jpeg

I made a new steam feed pipe from the valve to the injector as my first attempt looked ugly:

IMG_20200314_182233-01.jpeg

The steam injector all plumbed in with a slip on piece of pipe over the drain so that when I am running the loco I don't have to lean over and look under the footplate to check the water flow:

IMG_20200314_182246-01.jpeg

The new inline water valve for the injector is shown to the left of this picture (the length of the handle shaft needs a trim as it is too high, I can then use Loctite to secure it into position):

The shaft for the valve handle cut to size and secured with 603 Loctite (it sets very quickly). When the valve handle points towards the boiler then this is 'open' and water is allowed to fill the injector:

IMG_20200318_174141-01.jpeg

When the valve handle is pointed away from the boiler then this is the 'closed' position and no water will pass:

IMG_20200318_174153-01.jpeg

The setup with the valve handle position matches the axle pump valve (shown in the below photo with the longer shaft) so I will not get confused having to remember two valves with different positions (easily done when you are busy operating the loco on the track).

Here is the new valve bolted to the footplate:

The mesh cone idea did not work out as it is too fiddly to make and install securely so I have instead gone for a cylindrical mesh cover that is slotted into the base of the chimney and secured at the bottom with a steel ring:

IMG_20200322_131136-01.jpeg
IMG_20200322_131143-01.jpeg

The blower pipe I remade in an earlier post is also inside the mesh cylinder so it is not blocked.

To get the mesh out it requires the chimney base to be removed, however, I have seen many people at the club who use an air line to clean mesh so I should only need to remove it when it requires replacing from heat damage.

Looking good Tom!

As you're aware, I'm not much of an engineer, but that mesh looks like a very neat solution to me.

I guess you're not going to get much opportunity to run her for a while?

Cheers,

Andrew.

Thanks Andrew.

I am no engineer either but the only way to learn is to have a go. Silver soldering seemed like a dark art before I installed all the pipework for my new injector and now I am working on a club members loco to install his new injector because I have the confidence to do it (it is also my way of saying thank you to him for introducing me to 5" gauge and the club, this is the first loco I got to operate):

IMG_20200319_201203-01.jpeg

The loco is a LMS Stanier Mogul 2-6-0 and is very easy to operate.

Running for members of the public will not be allowed until further notice, however, club members are allowed to use the track for testing.

So after yesterday's announcement in the UK I cannot run the loco at the club track even for testing.

Still, plenty more to do!

The whistle and blower valves have had their damaged paint removed (I prefer unpainted anyway), stripped, cleaned then polished up:

IMG_20200319_142436-01.jpeg

The valves were then installed in the turret using Loctite and new annealed copper washers:

IMG_20200324_182444-01.jpeg

I am starting to think about the cab so I am going to make a prototype from Plastikard:

It was warm enough today for me to get the loco outside to test my steam injector install:



I love the noise it makes as it fills the boiler.

There was more footage, however, I had to delete most of it as my finger was over the camera lense!
