Calibrating mechanical joints is about accuracy, safety, and longevity. Begin with a basic inspection: ensure the doll is on a stable surface and powered down if it has any powered features. Gather simple measurement tools such as a protractor or angle gauge, a soft cloth for cleaning, and a notebook to record settings. Check for symmetry between limbs and joints. If you notice uneven movement, stiffness, or looseness, document the specific joint and the degree of deviation.
Lubrication and alignment are key. Use lubricants that are compatible with the doll’s materials and apply sparingly to avoid residue that could attract dirt. After cleaning, test the joints through their full range of motion and compare left and right sides. If a joint binds or is off-angle, adjust by tightening or lifting the joint’s stop or screw within the safe manufacturer-specified range. Avoid over-tightening, which can cause binding or material stress. Re-test movement, ensuring smooth, even motion without grinding or snagging. Record the final angles and any changes made, along with date and environmental notes, as climate can influence resistance and lubrication performance.
Seasonal considerations matter in Finland. Colder temperatures can affect lubricant viscosity and joint looseness, while humidity can impact corrosion risks on metal components. Recalibrate after significant seasonal changes and after any maintenance that touches the joints. If recalibration requires disassembly beyond basic steps or you encounter persistent misalignment, seek professional advice. Regular documentation of settings and outcomes helps you maintain safe, reliable poseability and reduces the risk of progressive wear over time.
