Bending and Shaping the Metal

After cutting out the main body shape, it’s time to bend and shape the metal to achieve the desired curves and contours. This can be done using various tools and techniques⁚

• Metal brake⁚ A specialized tool that allows you to precisely bend metal at specific angles.
• Vise⁚ Use a vise to apply pressure and bend the metal into desired shapes.
• Hammer and anvil⁚ You can use a hammer and anvil to gently bend and shape the metal, especially for curves and rounded edges.

Remember to be patient and take your time during this process. Gradually bend and shape the metal, checking your progress against your template or design to ensure you achieve the desired result.

Finishing Touches

After carefully cutting and shaping the metal, it’s time to give your DIY metal RC car body its final touches. This involves smoothing out any rough edges, adding details, and preparing the surface for painting. These finishing touches will enhance the aesthetics and durability of your body, transforming it from a raw metal shell into a stunning masterpiece.

Smoothing and Sanding

Once the body has taken its final shape, it’s crucial to smooth out any sharp edges and imperfections that may have resulted from the cutting and bending processes. Sanding is a crucial step to ensure a smooth and even surface for painting. Here’s how to do it⁚

• Start with coarse sandpaper⁚ Use coarse-grit sandpaper (around 80-120 grit) to remove any major imperfections, sharp edges, or burrs.
• Progress to finer sandpaper⁚ Gradually transition to finer-grit sandpaper (around 220-400 grit) to achieve a smooth and polished surface.
• Pay attention to corners and edges⁚ Focus on sanding corners and edges thoroughly to eliminate any sharp points that could cause injury or damage.

Adding Details

With the body smoothed and prepped, you can now add details to enhance its aesthetics and personalize its look. This can involve⁚
