Five Shunter Challenge Pt5: Gearboxes

Today we look at the gearboxes that will be fit to the five shunter kits.

My previous models have used Branchlines gear boxes, but I was really keen to try some of the gearboxes produced by High Level Kits for the x5 shunter challenge. In fact, one of the main reasons I purchased the Sentinel and 88DS kits was because the High Level Kits gear boxes were included in both kits. This would allow me to use these gear boxes test with the remaining three locos (as they require gear boxes to be purchased separately).

The instructions for the High Level Kit gear boxes are clear and well illustrated. It is important to work through the instructions and consider the placement of the various reduction gears. Don’t rush this.

I quickly put together the little 0-4-0 gear box provided with the RT Models Sentinel kit, ensuring the folding of the nickel silver pieces were at 90 degree angles using a hold n’ fold tool.

I test fitted the gear box to the compensated chassis and gave it a running in. Everything is running well. On to the next one…

Y10 Super Sentinel 3D Print

I have always had a thing for the rolling stock of the Wisbech and Upwell tramway. I have almost finished development of my BR 04 Shunter tram and I have already built both a J70 tram and Y6 tram. The one loco missing from my fleet is the Y10 Super Sentinel: A double cabbed tram that only ran on the Wisbech and Upwell for a limited time. A kit of this loco was produced by Impetus many moons ago, but you are probably more likely to find a pot of treasure at the end of a rainbow than ever see one of these Impetus kits available.

The Y10 is a relatively simple design and I had started work developing a 3D model for printing using the Blender software, but I then noticed that someone had produced a freelance OO9 version for 3D printing on the Shapeways website. To my delight there was also an ‘upscaled‘ version of the OO9 to OO gauge and I decided it was a good starting point.

The moulding is nice and rigid, and it has a wealth of detail inside the printed cab. Granted there are a few things I need to sort out. The cab doors are overly wide, but they should be easy enough to reduce down (understandable as this is a ‘blown up’ OO9 model). I also need to produce the cow catchers.

I’m really happy to finally have one of these models.

Cock O’ The North

My most recent purchase is the striking Peppercorn P2 Cock O’ The North by Hornby. I had a few concerns about some of the revisions in manufacturing when I ordered the model, but it does look amazing.

The running quality of my model isn’t so amazing, it seems a bit of a backward step in my opinion, but I have heard that there are some duff motors in some of the models. I have contacted Hornby for a replacement motor, which I will happily fit myself.

Five Shunter Challenge Pt4: Fitting and removing wheels

Today is a brief look at how I fit wheels to axles.

The five kits being built in the x5 shunter challenge either have Alan Gibson wheels or Markits wheels. The BR 02 is the only model with Markits wheels which are very easy to fit using the special Markits screwdriver. The axles have a square shaft that only allows each wheel to be fitted in one of four positions.

Alan Gibson wheels are friction fit, meaning that wheels are pushed onto a typical rounded axle. The brute force required to push or pull wheels off axles can be a bit scary, especially when you are fitting them onto your lovingly constructed chassis with brake rigging etc. For this reason I purchased some wheel fitting jigs. I bought a selection of cog and wheel ‘pullers’ and ‘pushers’ from fohrmann-WERKZEUGE. These tools have been very useful and limit the chance of damage to any of the models.

Demolition and redevelopment

Following the tragic events of the housing crash in late 2013, work men are now stripping away the concrete embankment at the Northern end of Brewery Pit. Rumours are circulating that the destruction of the brewery workers residential area has allowed the brewery company to push forward with controversial plans to expand the brewery’s warehouses and other facilities.

None of the demolition workers were willing to comment on the rumours or the validity of the claims and no one at the brewery facility was available for comment.

Five Shunter Challenge Pt3.4: Comprehending Compensation

This time we continue the discussion about my plans to build these five kits with compensation. As with all things in life, there are a number of different ways to fit a compensation system and the five shunters being built require quite different approaches. Today we will look at the horn block compensation system.

What are Horn Blocks?

This DJH kit of the BR Class 02 Shunter is built as a rigid chassis, but after attempting to build the chassis a few years ago, I decided that I would prefer to include compensation. The rigid chassis is constructed on horn blocks (bearings that look like brass cubes), so I decided to purchase a separate horn block compensation kit.

The driving axle shouldn’t be compensated on a 0-4-0, so I started to prepare the non-driving axle for compensation. The compensation kit instructions include helpful illustrations, but I was a bit scared to discover that I would need to cut a wider hole in the chassis for the compensated horn blocks to fit into.

I built up the outer horn block plates and used these to marked out the chassis with a permanent marker.

I then cut out the square gap using a fine hack saw with a thread-like blade.

The advantage of this horn block system is that you can manually adjust the height of the driving axle and the amount of compensation either side using screws. This means that even if my cutouts are not identical I can urh… compensate.. for that with the screws. I must admit that I am really pleased with the result and the chassis runs really well.

Cry Me A River

It has been a long time since I did any major work on Brewery Pit. I am aiming to have the layout finished for March so I can exhibit, but I keep wanting to modify things. There is a small river (it’s a stream really) near the front of the layout and I have already re-modelled it twice.

River Version 1

The first version of the river was down stream of a pond, but it didn’t look convincing and I pulled up the water course.

River Version 2

The second version was a straighter river with a more convincing bank and riverside vegetation. I used Woodland Scenics still water, but I soon found that the Woodlands Scenics material collects dust very quickly and it can be quite difficult to clean the dust off.

Most of the rivers that I find impressive on other peoples layouts are produced using painted acrylic plastic or glass, so I thought I would revise the river one final time.

River Version 3

Firstly I had to rip out the the old river. Most of the layout is laid with some tar-like rubbery substance that I used to stick down the track. This means that it is relatively easy to pull up bits of the railway (within reason).

I used transparent acrylic and mixed some murky green paint on the underside. I also painted the river bed with dull browns and greens.

I then positioned the acrylic on top of the river bed and buried back into the tar-like ground layer.

Finally, I reconstructed the river bed using DAS clay. I am really pleased with this version of the river as I now get a convincing reflection from the water. I can also clean the dust away easily with a damp cloth.
