Five Shunter Challenge Pt9: Keeping track

You might be wondering how I manage to remember where I am on all these different kits I am building and why I have (as yet) not lost any parts.

The main reason is that I keep each kit in a transparent plastic box. I have a current subscription to a set of die-cast cars and I use the plastic display cases to store each loco.

I also tick off each section or put a line through each section of the instructions that I have completed for each loco.

I also have a little modelling note book where I write down what I am doing and any troubles I am facing with the kit.

I know that all of this might sound obvious, but if you are like me, you can spend most of summer away from your modelling desk and when you eventually return to it, you just can’t remember what an earth you were doing. Keeping everything in separate boxes has really helped me keep track of all these different projects.

Five Shunter Challenge Pt8: A return to gearboxes

Now the rust calamity is over, I can return to the construction of the next gearbox.

The 88DS 0-4-0 gearbox is very similar to the one that I built for the Sentinel, but it appears to be a slightly revised design. Using the new flux and extra careful cleaning regime, I have not had any further issues.

I also decided on which gearboxes to purchase for the other three kits. Disappointingly, I have discovered that the small 0-4-0 gearboxes built so far will not fit the BR 02 (its wheel base is too long).

I have settled on High Level Kits Slimliner+ gearboxes for all three of the remaining kits with a 54:1 gear reduction. It is very important to note that the Slimliner+ was chosen because there is very little space inside the chassis for any wider gear boxes when working in OO Gauge. All those balance beams inside the Judith Edge kit frames leads to even less space. I never realised that those working in EM and P4 gauge have much more space to accommodate a range of gear boxes.

Five Shunter Challenge Pt7: The perils of flux

The dark art of soldering mystifies some, but I have managed to work my way through the mysterious technique by trial and error (with some reading). I remain impressed that in years passed I managed to build some brass locos with normal electrical solder. I now know that it is far easier to use a low-heat type of solder.

One lesson I am still learning is the best type of flux to use. Flux is a medium that helps concentrate heat on the joints that you wish to solder. Historically I have used solder paste, but I have discovered that although very helpful, it is virtually impossible to remove all traces of the waxy substance, which can lead to corrosion and the failure of solder joints. My primary issue with the stuff has been its ability to totally destroy paint work over time. Usually long after you have finished the kit.

Due to these problems I switched to a liquid solder a while ago, which is much easier to clean off brass. But as discovered in my previous ‘challenge’ blog, another problem arises: Corrosion. I have used Carr’s ‘Green Flux’ for a while, but this stuff really shouldn’t be left on anything for longer than a few hours. Annoyingly this includes my chassis jig, which the green flux started to eat at soon after I purchased it.

A cleaning regime is essential to eliminate any flux residue. Despite my aggressive cleaning regimes (boiling water, scouring powder, ultra sonic cleaning), some flux residue still manages to persist. I conducted some further research to see if there was a less aggressive flux that I could use. I purchased some different types of flux and I am currently using the O Gauge societies ‘Safety Flux’, which has so far, not caused me any further problems.

I have also started cleaning up work pieces (using the cleaning regime above) after every building session. Even if I plan to continue building in the morning.

Another trick I have used to stop the steel wheels and axles rusting is to store them in a plastic bag with some lubrication oil.

Narrow Gauge Simplex

Following a recent article in BRM by Phil Parker, I was inspired to complete my little 009 sentinel. I have constructed the ‘protected’ variant. Most of the work was already completed a few years ago, but I needed to make some adjustments to the rubber band drive (to stop the band rubbing on the supporting etch) and I needed to glue down the cab.

A spent a few minutes adjusting the chassis braces to keep the body square and there we have it.

Now he just needs to be sent to the paint shop.

Five Shunter Challenge Pt6: Oh no! It’s Rust!

Tragedy strikes! I returned to my kit builds today to find that three of the shunter chassis’ have acquired an unhealthy gathering of rust on the wheels and axles. Alan Gibson wheels are steel and they don’t seem to have taken kindly to the flux that I have been using to solder up the chassis. This has also affected the axles inside the gearbox I built last time.

After some swearing and general moodiness, I started to investigate how best to remove the rusty residue. I was surprised to find that soaking the model in Coca Cola was a possible remedy. This is apparently due to the acidic content of Coke (there are some quite amazing you tube videos that you can watch).

I set up a Coke bath and dropped the problem parts in and to my surprise, after 2 hours soaking in coke, most of the rust had vanished, and any remaining residue could be removed with a tooth brush.

Chassis for the Y10 Super Sentinel

The Model Rail Y1/3 Steam Sentinel RTR loco produced by Dapol has a wonderful mechanism and I confess to having a few too many of these little locos.

While at the Warley show in November, I noticed that Model Rail were offering one of the Y1 Sentinels at a considerably reduced price, so I quickly snapped up the model. This model will provide the chassis for my Y10 super sentinel (just don’t tell the Y1 that, he’ll get upset).
