Assembly Troubleshooting
Models we sell in the store come primarily in two materials: Plastic and Resin (sometimes Metal but that is not covered here). Each material presents unique challenges and requires specific handling techniques to ensure the best assembly outcomes.
Parts Not Fitting Properly
Plastic Models: Ensure no leftover sprue tabs or mold lines are obstructing fit. Gently file or sand these off. Sometimes, plastic cement can slightly melt and fuse parts together, creating a seamless fit.
Resin Models: Resin often requires more extensive cleanup. Carefully trim or sand away excess resin. Test fit before applying superglue, as resin does not fuse chemically like plastic.
Dealing with Warped Parts
Plastic Models: Minor warping can be fixed by gently bending parts by hand. For stubborn warping, submerge the part briefly in hot water (not boiling), reshape gently, then immediately cool in cold water.
Resin Models: Warping is common in resin. Submerge parts in very warm water until they become slightly flexible, reshape gently, and cool rapidly in cold water to set the corrected shape.
Handling Misaligned Joints
Plastic Models: Recheck the instruction manual and ensure correct orientation. Plastic cement allows brief repositioning. Hold joints firmly together for a few minutes until fully set.
Resin Models: Test fitting is crucial. Use a thicker superglue or a small amount of epoxy putty to fill slight gaps and provide better adhesion. Consider pinning heavy or load-bearing parts.
Removing Excess Mold Lines and Flash
Plastic Models: Mold lines and flash are usually minimal but can be easily scraped off with a hobby knife, mold-line scrapers or sanded smooth using fine-grit sanding paper or files.
Resin Models: Finecast Resin often has more pronounced mold lines and flash. Use a sharp hobby knife or fine-grit sandpaper while wearing a dust mask, as resin dust can be harmful if inhaled. 3D Printed resin does not generally have mold lines.
Safety Note: Always work in a well-ventilated area, especially when sanding resin, to avoid inhalation of fine dust particles. Wear appropriate protective equipment as needed.
