Westech was a pyrotechnic supplies company started back in the 1960's in Utah by Ralph Degn. Ralph wrote a series of "Technical Reports" designed to help amateur pyros learn to build fireworks. These "TR's" as Ralph called them, marked the blossoming of a new era in fireworks making literature. Before that time, very little useable literature had been written in the 20th century about modern fireworks making. Westech has long since passed from the scene, and Ralph has moved on to other things in life. The original TR's were pretty crudely self-published booklets, each one dealing with a single fireworks topic. Many of them had hand-drawn illustrations. Now, Bill Schmidt has "re-created" the TR's using modern computer technology and published them in color in a great new book called the Westech Fireworks Manual. I think it ranks among the most useful fireworks craft manuals ever done. The illustrations are among the best ever done in fireworks literature. I know of no other fireworks manual using color illustrations as profusely as this book. The list of fireworks projects is extensive. Click here for a description of contents.
