Many people use flight cases to transport delicate musical gear. Gigs require travel, and you want to make sure to protect expensive musical instruments that can be damaged when you go from one gig to the next. You can buy flight cases, but u konw the process of building a flight case ?if you  want to build a case for your instrument ,this artical you shold learn. If we wannt to build a Guitar case ,we need to measure the instrument or equipment that intend to transport in the box in order to get an idea of how big it should be.
