Part 1 - something to run - the shunter

Following on from my points in my first post about why O gauge was a good idea for me to try something new, I'm also wanting to try a number of new techniques that I haven't done before.

 

My first part - albeit bizarrely - is to attempt a brass kit, something I've never done before.

 

Having grown up near Chard Junction, and having fond memories of the Ruston 165 shunter pottering around the yard moving milk tanks around, it seemed a good place to start. I contacted Mike Edge, and after a few phone calls, the kit, some wheels and a motor/gearbox were all in the post on their way to me.

 

A few years before this project was even an idea, I managed to track down the Chard Junction shunter. As a replacement for the Ruston 48 they had, the 165 was sold on in the mid 80's when the dairy abandoned milk by rail.

 

Some enquiries later tracked it to the Cholsey and Wallingford Railway, who had then sold it on to the Mid Suffolk Light Railway, where it had been restored to working order. A few phone calls later resulted in a day out at the MSLR, armed with camera, where I took a number of shots "just for old times sake".

When I knew the shunter, it was in all over bright (but grubby) yellow, with a flashing amber beacon on the cab roof for working in the concreted yard. But, she was still running, and although I regret not being able to video her in action and capture the sound, the 30 year old memories came rushing back.

 

So, here I am, about to embark on recreating those childhood memories with some bits of brass.

 

This evening, I made a start on the kit. I assembled the motor and gearbox (Mashima 1833 plus Branchlines 40:1 gearbox) - which I have never done before. One or two minor glitches, but it basically went together first time and ran sweetly. I'm quite pleased with it, although it's very basic.

Next challenge is the chassis, and once I have got the chassis together and running sweetly, I'll be installing a German DCC sound chip I picked up from a trip to Digitrains in Lincolnshire. It's not perfect for a Ruston, but being a generic "small diesel" I reckon will sound about right when it's installed. It's been tested in a OO gauge loco and sounds fine to me. There's few people out there that'll be able to tell me it's wrong, and let's be honest, it's my layout so nyah!

 

More to come. No burnt fingers yet with my nice new 60 watt soldering iron.

Next part completed this evening... the basic chassis. I can't complete it and put the two parts together this evening as I need to ream out the holes for the wheel bushes, and guess what I can't find.

 

A trip to Maplin in the morning should furnish me with the appropriate tool.

All those solder joints are inside so the fact they're a bit messy doesn't really matter as they won't be seen unless the shunter tips over 180 degrees - and if that happens, the dodgy soldering will be the last thing I'll be worrying about :)

This morning, I bought myself the reamer I needed to open up the holes slightly as required to get the "tight fit" needed for the bearings for the axles.

 

This evening I used the reamer, then soldered the bushes to the chassis as per the instructions - and then discovered I shouldn't have soldered bushes to the gearbox, which isn't mentioned in the instructions, as nothing fitted! A few choice words and a little desoldering later, all was well.

 

The wheels were then assembled and put together, with the worm gear screwed in as required, and the whole lot put on a length of flexitrack and power applied.

 

There's a little tweaking still to be done to make the running smoother, but to all intents and purposes, it's running exactly as it should be.

 

My next task will be to wire up the sound chip that I plan to put in there, and find somewhere to hide it. In my OO loco it stayed in the cab, but I reckon there should be plenty of room inbetween the chassis sides to hide the chip and its tiny, but powerful, speaker. If the sound can vent to outside then I don't need to worry about making holes, and as the speaker has its own built in soundbox, no further work needs doing.

 

I've waffled enough. Here's the video.

Any more progress on the build ?

 

I've looked at 00 kits and always chickened out - part cost, part doubting my skills, part because I don't have much in the way of engineering tools, not even a fixed vice !

 

I want to absorb as much as I can from other people's builds ........ I fancy a Highland 4-6-0 heavy goods and can't ever see the RTR market making one.
