The shuttle

The shuttle consists of a rounded cork base covered in a thin layer of leather. Sixteen goose feathers are attached to this base. Each shuttle requires three birds because a wing has six feathers and manufacturers cannot mix those from left and right wings, because they have different curvatures. Most high-quality shuttles tend to use feathers from the left wing of the bird, considered stronger. Note: all the feathers come from birds that have been raised for food.
The length of the shuttle may vary between 64 to 70 millimeters, provided that all feathers are equal length. Each shuttle should weigh between 4.74 and 5.5 grams.
