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.

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.

|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.|
