turbo1889: Great reply, you totally got what I was asking and provided some excellent insight. I am really not 100% sure how to answer some of the questions I need to ask to refine my design. I will take what you said into consideration when I decide which way I will go. I figure if I choose my jackshaft out gear to be easily changed, then that will give me some room to refine my total reduction cheaply and easily. Thanks again.
