Problems encountered during model assembly
All our models are carefully selected, designed and tested many times. The quality is no problem. Considering the difference in hands-on ability of each person, it is inevitable that some problems will occur. Here we share some tips for model assembly
Due to the natural properties of wood, wooden parts are fragile and you need to use proper force to put them together
All wooden model drive parts or modules. Always use sandpaper to sand and wax block to lubricate. Make sure that the drive parts will work properly. This is the key to successfully completing your wooden model.
Stay patient, follow the instruction steps, pay attention to the front and back of the parts and orientation and you're done.
Good luck completing your model!
