I have just been gifted a set of all ten already in pdf format by Martin Thomas over in the Facebook Shopsmith Owners Group. They are very clean scans and thus far very much welcomed.
Doug got me started and Martin, seeing what I was working on has refocused my efforts. I will closely examine them to take the best quality forward.
Thank you for your comments, your friendship and for being one of my Shopsmith mentors.
UPDATE: Martin's PDF scans are of such quality that I will simply rename them to reflect his contribution to this project.
I must surmise that Martin's originals are not as yellowed, or his scanner is far superior to mine. These scans are excellent and need no further work.
I have reached out to him, as I am missing Lesson 9 in his bundle of PDF's. As soon as I receive that I will add the entire collection to My Google Drive for everyone.
