ABSTRACT:
The invention relates to a method to make a perforating gun for use in oil and natural gas wells comprising the steps of: obtaining a length of a first tube; cutting scallop holes into the first tube forming an outer layer; placing the outer layer in a holder; cutting a second tube to the approximate length of the outer layer; pulling the second tube into the outer layer forming a laminate structure having a first and second end; repeating the process for a desired number of layers in the laminate structure; machining internal structures into the laminate structure; inserting the loading tube into the laminate structure; and forming thread protectors in the first end and the second end of the laminate structure.
