Why Puzzle Parts Don’t Fit
Before fixing the problem, it is best to identify why the problem occurs. Here are common reasons why puzzle parts don’t fit.
- Manufacturing tolerances: Wooden puzzles have laser-cut pieces. This means their edges are precise. However, there may be tiny variations in the thickness on occasion. This could make them slightly off-shape, leading to gaps and poor.
- Environmental Condition: Wooden puzzles are sensitive to humidity and temperature. Thus, wood absorbs moisture. Wood or paper-based materials can expand or contract under certain environmental conditions. For example, a piece that fits perfectly today may not fit the next day because of humidity.
- Sequence of assembly: Occasionally, it is not the piece that is out of place, but the sequence in which a piece was laid beforehand. If you’re assembling a piece and a crucial step is misaligned, it will cause other pieces not to fit in. Installing a part too early or too tightly can cause other pieces not to fit in.
For example, a misaligned wall or crooked base can make the next step harder to place your puzzles.
- User handling: Mishandling the puzzle pieces can cause them not to fit.Pressing harder or at an angle may also make them bend or fracture, and this makes them hard to fit perfectly.
- Misplaced Pieces: This frequently happens in the assembly process. Sometimes, you may feel a piece fit doesn’t fit in a particular place, only to discover that it is actually perfect somewhere else.
- Human Error: Overlooking a small piece, not placing a piece in the appropriate position, or even accidentally putting a piece in upside down can cause fitting problems.
How to Fix Miniature Parts
You can use any of the following methods to fix our Rolfie miniature parts.
1. Sanding Pieces
If a puzzle piece doesn’t fit, sanding may put it in shape. The goal is to remove any excess or rough edges and give you a piece with a smooth fit. Use a fine-grit sandpaper or a nail file to smooth the edge. Check the fit often to prevent excess sanding.
2. Assisting with Pressing "Tools"
There are other times when the pieces just do not fit due to the inability of your fingers to exert even pressure. Work with a piece that labeled "TOOL" in your kit to press pieces into place without breaking them and damaging your fingers. In the absence of a flat tool, you can use a coin or the side of a spoon to put constant pressure without bending the piece.
If the piece is delicate, see [How to Handle Fragile or Thin Parts During Assembly] for guidance.
3. Gently Tapping with a Hammer
Tap pieces in place using a hammer. Place a soft cloth or cardboard over the piece and use a light force to tap till it clicks into place. Do this only for sturdier parts like wooden walls.
4. Securing in Place with Strong Glue or Double-Sided Tape
If a piece continues to pop out, wood glue or two-sided tape can help to hold it down. While glue adds strength for DIY miniatures, puzzles only need glue if you’re permanently framing the design. Do not let glue seep into visible areas.
5. Filling Gaps with a Coffee Stirrer or Toothpick
Space between the puzzle pieces can prevent them from fitting well. Use a shim for this. Use flat coffee stirrers or toothpicks, and paint them to match the color of your kit.
Pro Tip to Fix Your DIY Miniature Parts
- Recheck interior parts and try to rework them to solve issues.
- Put stubborn joints under clamps after gluing.
- Use scissors to cut off large sections in paper-based kits.
- Keep a toolkit handy. Whether nail files, glue, tape, or a smaller hammer, any of these can solve most problems.
- Be patient and flexible. You may need to step back and reassess your work or try a different approach.
