Before I retired as an engineer I sometimes had to train or explain work processes to younger engineers. So I had some experience in trying to put out a set of instructions. Today its easier with computers, small cameras, and pdf creation software to document a process. To put one of these how-to's together just remember to document clearly the steps you do. Be sure to include all steps and don't assume the reader will understand everything. Some people may not have the experience and are trying to learn.
Thanks for everyones appreciation. Some of you like Pete have contributed to TU that helps me so I wanted to do my part to pay it back.
