As promised I am going to outline the restoration of my Greatgrandads Maise I have now found out it was built in 1947 and run only a few times. My Dad is doing the restoration and I am helping where I can, as I still have my speedy that I am trying to get finished. This is the condition it was in when collected,  And the tender was in a bit of a rough state too. |

 It has some corrosion and a lot of flaking paint |

Hi Doug,
That is so cool to have a loco from 4 generations back! I’m sure you & your Dad will do a great job of getting her back to a fine fettle & enjoying that first ride, with many more to follow!
As an aside my wife took a picture of me driving my Tram with my dad, daughter & 2 grandsons on board.
Cheers Kerrin

After some rapid disassembly it looks like this,   It’s nice and oily but there is a bit of surface rust and it needs a complete paint job. Before we took it apart we gave it a light run on some low pressure air. It looks to be quite good although the reverser won’t go into full gear as it fouls the back head pipe work. I am going to look at altering the reverser to give it a bit more clearance. |

The boiler came off ok   The back head is very busy indeed with vacuum brakes and all the other valves and pipes. |

Looking forward to a reborn Maisie.
I have done it to the one I own and it is very satisfying, taking saomething old and making it like new.
All the best.

That looks like a great project, looking forward to seeing it move along!!

A few bits have been cleaned and primed  And I have spent some time cleaning the boiler to get a look at how it was made  It looks quite small next to speedy boiler  The back head is really busy and I love the little valves he made they all work very well indeed  |

Like a lot of Maisies I have seen, the bottom fitting of the water gauge looks to be below (or at least very near) the level of the firebox crown and I wonder whether an extended lower gland nut might give you a safer margin between "water just in sight" and "crownsheet uncovered" ...
It may be OK as it is if the photo gives a misleading impression, but it is usual to have the bottom nut a little way above the firebox crown to compensate for capillary action in the glass itself.
Just a thought...
Good luck with the project.
Malcolm

Hi Doug,
You will have a cracking loco with (I am very pleased to note) original boiler design rather than the one in the later construction book with combustion chamber and 4 superheater elements.
The reverser hitting the front side of the boiler or front cab sheet is a well known issue, and easily rectified.
In respect of Malcolm's point about the water gauge I don't recall the one I did having this fault, but a bit of rolled up brass shim slid down the outside of the gauge glass will solve the issue in your case.
It is a great loco in miniature and very easy and fun to drive and fire, and with careful adjustment of the springing easily able to haul 4 - 6 passengers.
I am very fond of the very similar LBSCR H2 Atlantics especially in Maunsell SR livery.
Cheers,
Julian

I had a good look at the height and the bottom nut is above the crown so any water in the glass is ok but I agree it is ver close, however I think Julian and Malcolm are right and it’s a good idea to raise the minimum up a bit to cover as it is an unusually long glass.
I was surprised at the complexity of the brakes having a full vac system on both the loco and tender.
There also seems to be a vacuum pipe protruding from the front buffer, is that normal?

There also seems to be a vacuum pipe protruding from the front buffer, is that normal? Yes Doug, the loco may need to couple to a train in front and thus needs the pipe to operate the brakes just as when at the rear. Also, from the archive film that I've seen when using a vacuum controlled turntable the train needs to supply the vacuum and so needs connections at both ends, so that it can use the turntable no matter which direction it is facing. I'm very interested to hear of your fabulous loco with it's vacuum controlled brakes for both loco and tender, I've not seen this before in 3 1/2" (perhaps Eddie's is, not sure), it seems rare enough even in 5". Keep up the good work sir, clearly the model was built with much skill and pride... Pete |

On my vacuum braked locos, the front standpipe is a summer as I don't anticipate double heading on 2.5"g! Also it means a lot fewer joints that could potentially leak.
When you can stop the train from a little Lever in the cab, you won't want to go back to heaving on the driving trolley brake!
IIRC the LBSC design for the vacuum brakes on Maisie is for the "simple" vacuum brake not the fail-safe version.

Sorry - wretched predictive text - that's "dummy" not "summer" ... doh!

Doug,
I have recently acquired a part built 3 1/2" gauge Betty without its boiler. It is a 90% complete tender, a set of engine frames and a box of castings. I have noticed that the boiler barrel design is similar to Maisie i.e., they are both 4 3/8" diameter but there doesn't appear to be any design details relating to boiler lagging and cleading. As the smokebox on Betty is also 4 3/8", my guess is that LBSC didn't bother to insulate the barrel but might have at least added a cleading sheet wrapped directly onto the copper barrel maybe?? Your Maisie has obviously been running very successfully in the past and it looks like it at least had cleading. Does it have any insulation underneath? Would you be kind enough to describe the arrangement please?
