The underframe is where I invariably start with any model because everything that follows can be done with the model on its wheels.

I was introduced to foam cradles, that originated as worktop edging protective covers, by a friend who liberated some from a skip. I use them for most models that I work on now. Having exhausted the supply that I, in turn, liberated from waste disposal receptacles, I decided to buy some direct from a manufacturer, but had to order a minimum quantity. I now have enough to last workshops, demonstrations and me for several years!

The model is inverted in a foam cradle.

In this instance I'd like to keep overspray to a minimum (not always the case) so make use of another precision instrument to give a little bit of control over the paint flow.

I have a selection of pieces of 2mm A4 sized greyboard, that have been cut into strips of various widths, that can be used to rest on the turntable and against the edge of a roof, a body and anything else that is to be airbrushed.

The paints to be used for the underframe are Humbrol Matt Black, Matt Leather and Lining Orange. The last of the three is introduced because the leather now has a green hue to it and needs the orange to bring back the gingery hue that is just right for track dirt on underframes. I have used up all of my stash of older style Matt Leather! I have been using Railmatch Frame Dirt and Weathered Black occasionally, but still prefer the Humbrol paints.
