Choosing the Right Modelling Tools
Good tools make modelling easier and more enjoyable. From the right drill bit for pinning parts to the correct magnification for painting eyes on 28mm figures, having the right equipment for the task at hand saves time and frustration.
Workbench lighting is often overlooked but makes a huge difference. Aim for 750-1000 lux on your work surface with daylight-balanced bulbs (5000-6500K) to see true colours. A combination of overhead lighting and an adjustable desk lamp provides the best coverage without shadows.
For airbrushing, the compressor needs to deliver a consistent, pulsation-free air supply at the pressure your work requires. A compressor with a tank of at least 3 litres smooths out pressure fluctuations. Our calculators help you match equipment specifications to your actual modelling needs.
