Step-by-Step Instructions

  1. Gather Supplies

    • thinner, oil paints, brush, paper towel, mixing cup, and paint pipette.

  2. Mix the Filter

    • Pour a decent amount of thinner into the mixing cup.
    • Add a tiny amount of oil paint to the thinner (approx. 95:5 ratio of thinner to paint). Mix thoroughly.
    • Test the mixture on paper. It should only lightly tint the paper, not create a heavy coat.

  3. Prepare the Brush

    • Load your brush with the mixture, then carefully wick off excess onto a paper towel until only a slightly damp sheen remains on the brush.

  4. Apply the Filter

    • Gently brush the filter onto your model, applying it in thin, even layers. Let each layer dry before applying another.
    • Reapply as needed for desired color effect. Remember, filters are meant to subtly alter base tones, not build up heavily.

Tips

  • Don't use too much paint. A very diluted mixture is key for a successful filter.
  • Avoid overloading the brush. Wick off excess paint to ensure a thin, even application.
  • Filters are for adjusting base tones and adding subtle color variations, not for accentuating detail.
  • Making your own filters is significantly cheaper than buying pre-mixed ones.

Common Mistakes to Avoid

1. Incorrect Filter Media Selection

Reason: Using inappropriate materials can lead to ineffective filtration or damage to your model.
Solution: Choose filter media with the correct pore size and material properties based on the specific contaminants you're targeting.

2. Poor Seal Formation

Reason: Leaks around the filter housing compromise the filtration process and can introduce unwanted particles.
Solution: Ensure a tight and secure seal using appropriate adhesives or gaskets to prevent leakage.

3. Improper Sizing and Placement

Reason: Incorrectly sized or positioned filters will restrict flow or fail to remove contaminants effectively.
Solution: Carefully measure and design your filter to ensure proper flow rates and optimal contaminant removal.

FAQs

What materials do I need to make DIY model filters?
Common materials include readily available items like colored gels (found at craft stores or online), clear plastic sheets (like acetate or transparency film), and strong adhesive. You might also need scissors, a ruler, and possibly a laminator for extra durability.
How durable are DIY filters compared to store-bought ones?
Durability depends on the materials you choose and how carefully you construct them. Using laminated sheets and strong adhesive will significantly increase their lifespan. While they might not be as rugged as professional filters, they offer excellent value for the cost and are perfectly suitable for many applications.
