Bury goods 0-4-0
This scratch build is something I have been wanting to do for years but have never quite plucked up the courage.
There are several 'sticking points' in modelling a bar framed Bury loco, the obvious one being the distinctive wheels. All Bury locos had them so unless you get those right you might as well not bother with the rest. Thankfully, a friend very kindly drew some up and 3D printed the centres to be fitted into Gibson tyres of the appropriate diameter. However, I found the prints to be exquisitely detailed but not very strong. So I decided the best way forward was to use one of the prints as a master and cast a set in white metal. These came out well and are considerably stronger than the prints. The down side is that they are conductive so once cleaned up on the lathe and fitted with tyres, the centres had to be bored out and a tiny plastic sleeve forced in before being bored out again and secured to the axle.
I first made a master for the bar frames out of styrene to use as a master for casting them in white metal but decided that the castings would not be robust enough so instead some brass bar was used to fabricate the frames. They're now plenty strong enough for the job as I made them slightly chunkier than the originals for peace of mind. Springs were made from some very useful etches, bearings added and a buffer beam built up from nickel silver and brass.
The buffer beam was soldered in position but a trial fit of the wheels revealed that the buffer centre height was too low by just over 1mm. Rather than unsolder and move the buffer beam higher which would look daft, I decided to unsolder the bearings and fit them lower down in the frames. This sounded like a horrible job, unsoldering the bearings whilst not accidentally disturbing any other soldered joints. However, it went well and before refitting the bearings I cut and fitted the footplate to ensure everything was square and spaced properly. This actually made it easier to get the bearing in exactly the right place. Lesson learned for when I tackle the Bury passenger 2-2-0 later on.
The photo shows progress so far. The next job will be to scratch build the gearbox and ensure the motor sits at the right level so it can hide inside the boiler. Something tells me that this won't be particularly straightforward but I feel up for the challenge. Wish me luck...!
