Airbrushing

I don't know if this is a topic we have discussed before however it seems like a good idea to bring any thoughts, hints and tips on the subject together in one thread.

Several thin coats are much better than one or two thick coats and a priming coat is always a good idea no matter which material is being painted.

It is a good idea to obtain a large card box and create a spray room within it with a turntable upon which you can place the subject. This keeps the paint within a contained area and being able to turn the model rather than you having to work your way around a static model makes airbrushing more manageable.

Why don't a few of you give it a go on an old loco body that is a bit tired?


You may be able to create that loco that you have always wanted but which the manufacturers always seem to overlook!


And of course airbrushing works well for scenic backdrops, buildings and other model railway subjects. You can practice on a cheap Dapol kit before progressing to something more expensive.

Those who may be interested in experimenting with airbrushing probably won't wish to spend too much money initially however the thinking behind tool investment over a lifetime is sound.

Appreciating that low cost (low pressure?) systems clog up and may not perform as well as the top end kits would those in the know have any ideas on good starter sets?

And where would paint and transfers be sourced from?

There is Fox and another company whose name I cannot remember right now (they probably advertise in the mags) that supply transfers but how about paint?

And what sort of paint volumes are offered/required and at what sort of prices?

Its these practical questions and answers that make entry into the world of airbrushing relatively straightforward. I've got one or two old and very playworn Dublo locos and other bits and pieces that I would like to renovate and have been thinking about this airbrushing thing for a long time.

I have up until now been using Halfords spray paints on car models however railway colours are not the same as those used by Ford and Vauxhall or in those TV house makeover programmes. Although there may be some who would love to have a TV house makeover with a BR blue and yellow theme using Mk1 Coach seats for TV viewing in the lounge!

I would guess that if you airbrush the track you simply use a track rubber or fine sandpaper to remove the very thin coat of spray from the top of the rail. Care might be needed around points. However if you seperately wire the point blades to the main rails from under so that you are not relying on the point rail itself to conduct power then this is not an issue.

There is an airbrush expert at Warley MRC who spent a good hour with me last night providing tips and pointers. He recommended a twin action gravity/suction Aztec airbrushing set for about £99 which comes with 6 heads and several reservoir sizes
and with suggestions of where these can be purchased in the local area. He said to mention his name and Warley MRC and I might get good discounts!

He claims that these are the easiest of airbrushes to clean as the nozzle is a screw fit and due to its mode of operation only the nozzle (not the jet) has to be cleaned which is a dip in thinners so dead easy. A reasonably quiet compressor with an air chamber to smooth out airflow giving about 30-50psi might be another £70 but again well worth it apparently.

He said to forget Revell and other low cost hobby brushes as you would quickly loose interest in airbrushing as a result of the relatively cumbersome design and prolonged cleaning required.

And he said the only way of getting Hornby like paintjobs is to use an airbrush. There is absolutely no other way in his opinion. For masking best to use selotape. Standard masking tape is too thick and leaves an edge. Take the "stick" off the tape by taping it to and pulling it off cotton material a few times.

Wifey is talking about birthday presents!

However could she mean a role of selotape?

Did think that myself about the tape tip. Maybe if you use a lint free material if such a beast exists.

What are the ideal masking solutions as standard tape is a bit thick.

I must admit to being convinced by the 37 weathering job and its great to hear the positive feedback on the Aztec airbrush as the modeller at the Warley MRC was very sure of its benefits also. He uses both enamel and acrylic paint and even older enamel paint with lead in it!


This has to be a product worthy of further investigation.
