@the I started out with reading Polt's The Typewriter Revolution (Countryman Press, 2015) which has some good basics. Consulting his basic typewriter restoration page was very helpful too. Beyond that and knowing the names of some of the basic parts, the rest is just following along with YouTube videos and practicing on getting my own machines up to snuff. It's almost amazing what you can do with a single screwdriver, a squeeze bottle of paint thinner, canned air, and a toothbrush.

I did just get a copy of The Manual Typewriter Repair Bible, but have yet to really crack it. Hopefully it'll up my game for this upcoming repair.

It's been a very satisfying and useful little hobby these past 4 months. If you want to crib from my notes...
