Gunpla 101: Your First Kit – Where and How Do I Actually Start?

So, you’ve just bought your first Gundam box. You open it up, see five sheets of plastic parts, a tiny sheet of stickers, and a manual that might be entirely in Japanese. Don’t panic. Building Gunpla (Gundam Plastic Models) is essentially like building a high-tech LEGO set, but with a few specialized tricks. In this guide, we’re breaking down the absolute basics using the HG Demi Trainer from The Witch from Mercury.

1. Decoding the Manual

Newer kits (like those from the Witch from Mercury line) usually have English translations [01:56]. However, if you’re building an older High Grade (HG) or Master Grade (MG), you might be looking at 100% Japanese.

• The “Part List” Secret: Before you snip a single piece, check the parts list at the front. If you see an “X” over a part on the runner, it means that piece isn’t used for this specific build—it’s just an extra from a shared mold [03:40].
• Icons Matter: Look for the “x2” symbol (build two of these, like arms) and the “Diamond” symbol, which indicates a specific assembly order that must be followed [07:59].

2. The Essential Toolset

You don’t need a workshop to start. DK Hobby recommends just two things:

• Double-Sided Nippers: Good for the first “rough cut” from the plastic runner.
• Single-Sided Nippers (e.g., GodHands): These act like a razor, slicing the plastic rather than crushing it, which prevents those ugly white stress marks [10:39].

3. The “Two-Cut” Technique

Never cut the part directly against the runner.

1. The Rough Cut: Use your Nippers to cut the “gate” (the plastic rod) about 1/8th of an inch away from the part [06:46].
2. The Clean Trim: Once the part is free, use your high-quality nipper to trim the remaining “nub” flush with the surface.

• Pro Tip: If you see a small white stress mark, use your fingernail to rub it. The friction and pressure can often make the mark disappear without any sanding [07:43]!

4. Stickers and Assembly

• Placement: When the manual shows a side profile or “zoom-in” view, pay close attention to the orientation of the piece. Some parts look symmetrical but actually have a top and bottom [09:06].
• Click it in: Most modern kits are “snap-fit,” meaning no glue is required. If a part isn’t clicking, check for leftover plastic nubs—they are the #1 cause of parts not fitting together.
