Weathered Skips in Spring

A lovely spring weather prompted me to venture out in the garden to photograph 2 skips of the German DIN-type. The skips have received a tough hammer weathering, paint and a weathering with Vallejo chipping medium.

Since I wielded the hammer over the hapless skips, two of them have been covered in rust coloured acrylic paint. I covered the wheel treads with masking tape cut to fit. Usually I have been adding rust after the main colour (on my skips a dirty dark grey). This time I took another approach adding the rust first. On top of that I air brushed a layer of Vallejo chipping medium. A fluid that reacts easily with water lifting acrylic paint added on top of the fluid. After the chipping medium had dried, I applied the covering dark grey. I painted numbers on the skips. On one of them I used an etched stencil, the other got a number painted free hand. After a few hours I took a flat brush, moistened with water and started working the surface. First with light strokes to add the water and a few seconds later with heavier strokes to lift and remove some of the grey paint and expose the rust underneath.

My first attempt of weathering using chipping medium.

Having never used chipping medium before I was not sure if I could continue the weathering proces before adding a protective layer of acrylic varnish. I took a chance and gave both skips a wash with heavily diluted oil paint. I used turpentine to thin the oil paint and the mix didn't affect the chipping medium. The inside of the skip body was 'massaged' with graphite powder. Only then did I seal the work with matt varnish.

 Still a lot of weathering remains to be done. Gravel dust and worn metal must be applied and I'm also contemplating to add some more texture to the weathering. In this scale rust really should have some texture and not be completely smooth. I better sink into my arm chair and do some thinking.

A new and unweathered skip has been added to the train to show the difference in appearance.

Due to the corona virus I have been working from home for a week and a half now. The railway business is still working in full gear so I have actually been extremely busy as a lot of extra tasks have been generated by the virus. For me there is no sign of isolation modelling progress.

Rail Order in Transit for Nystrup

Based on my own research and advise from knowledgeable modellers I have now sent for six lengths of Peco IL-7 FB Code 143 rail. I added a few extra items for track building as I had the credit card out of the card holder. A month ago I reflected over the Peco SM32 track I had acquired for test running and designing my 16 mm scale indoor layout.

Not least the comments and subsequent mail from blog reader Nick Curtis assured me that the Peco Code 143 would be a good rail size for my experiments scratch building track in 1:19 scale.

Nick Curtis had just received his Code 143 rails and posed a few skips on them to illustrate the quite nice relationship in size to the Peco rail. Photo: Nick Curtis.

Not only the rail's height fitted my needs for a realistic type of rail for Nystrup Gravel. The profile is also a much neater representation of a Vignoles profile than my current standard Peco SM32 Code 200 track.

I'm now looking forward to the package arriving from Germany. I shopped at Wenz-Modellbau where I also shopped track items when modelling in 1:35 scale.

A big 'thank you' must go out to anyone responding to my blog helping me to discover new methods, products and suppliers. A particular thank goes out to Nick Curtis for sharing info and images.

Hammer Weathering Applied to Skips

Some of the six skips of German DIN type I aquired last year have been on the workbench to receive some punishing before painting and weathering. Most skips lived a hard and productive life leaving traces like bulges, bends, dirt and corrosion.

A line of skips showing some of the irregular buckling and wear resulting from many years of hard service.

I'm currently drilling three holes in the skips' body's bottom centre line. On the prototypes the holes helped to drain water from the skip bucket. I marked out the position of the holes with a simple jig to ensure equal spacing. Each hole were then started with a hand drill and drilled through with a Dremel.

With the body off the frame I first used flat nosed pliers to lightly bend parts of the metal work. I predominantly added bends to corners and exposed edges, where the skip body would most likely suffer contact with excavator shovel, structures or hit the ground during unloading or derailments.

I also tested if I could replicate the damage inflicted when trying to empty the skips from dried or frozen gravel sticking to the skips' sides. Workers used sledge hammers or iron bars to work the outside of the skip body to release sticky loads. At Nystrup particularly the clay rich overburden could be hard to release from the skips. After years of treatment like that many skips had a pronounced inward bulging.

I went about the process quite simply. I went to my shed where I keep tools etc. On the workbench there I used a piece of wood to position the skip body. With a hammer I made a series of quick blows (well directed, of course) to the skip body. The result was dents of different shapes depending on angle of attack and strength of force. I kept testing if the body still moved freely on the skip frame.

At the workbench in the shed. Ready for hammer weathering!

Bang! Hitting with a corner of the hammer's sharp end produces a small diameter depression in the metal. The skip's frame is standing by for testing if the body looses its overall shape.

With 5-8 blows by the hammer I decided to take a break and examine the results. While the damage done by the hammer can be repaired to a certain degree with the same tool, it's better to stop and assess the result.

Two skips with hammer weathering. The rusty skip has been prepared with two different rust colours in preparation for air brushing with chipping medium and a covering paint. Its wheel treads protected by masking tape. The grey skip has only had the hammer treatment.

While it may not be too obvious in this image, both skips have a random pattern of hammer damage added.

Ferguson for Nystrup Farmer

Recently I have been working on my diecast model of a Ferguson TE-20 from Schuco. I aquired the model in october 2018 and examined the model in this blog post.

With open bonnet this is how the Ferguson looked when just arrived.

The finished Ferguson photographed on the road plank in my garden.

However much I like the Ferguson tractor my model couldn't stay shiny and factory fresh. Most Fergusons came to Denmark in used condition. While they were of course given a thorough cleaning and mechanical check up before sale and taken care of by their new owners, they were work horses. I wanted my model to look like a well used Ferguson.

The first layers of paint have been applied. The tractor has been readied for a full coverage of matt varnish with a tiny amount of sand colour added for at dusty look. Areas not destined to be matt or dusty are covered with masking tape or glue paste.

I began the proces with minor painting of details and all the linkages' black pins were covered with grey. The exhaust pipe was given a mixing of different dark brown and rust colours. Details like spark plugs and petrol filter were given contrasting colours having consulted several colour images online. I added green putty to represent dried mud on the tractor's lower parts and wheels. I worked the putty with an old stiff brush while drying to add texture. The puttied areas and surroundings were covered with light earth colours throug the air brush. I also air brushed a thin layer of dark grey on the engine block and radiator. The license plate is a piece of plasticcard fitted with a decal from Skilteskoven.

Weathering progressing. The challenging task of weathering the wheels has begun and the first stages done.

Switching from acrylics to oil paints I gave all areas around linkage points and bushings a thinned lick of black. With the same thinned black oil paint I gave engine, radiator, petrol tank and areas around the bolts on the wheels a wash to bring out the detail and to illustrate oily dirt. I finished this phase off with an air brushed layer of matt acrylic varnish with a tiny drop of light sand added.

With the varnish dried I started adding some small scratches around the tractor. I consulted prototype pictures to see where they usually occured. I kept the scratches to a minimum as I'm modelling a tractor in the early to mid fifties and not a 1980's wreck. I also added petrol spillings on the tank under the bonnet. With those minor tasks done I started weathering the tires. A do or die task on most tractors, where the large tires are very noticeable. I used a thin mix of water and acrylic paint to add the dust between the tire treads. When dry the paint was scratched with a steel wire brush. I rubbed ground up pastel chalk on top and sides of tires and finished off with a covering of matt varnish. I then sanded off any paint on top of the tires treads to expose the original rubber. With a burnishing with graphite powder on seat and foot rests and some gloss varnish on freshly oiled spots, the model is now ready to serve a farmer on the outskirts of Nystrup.
