We have a long way to go before this unit is ready to rock and roll again (if it ever will be), but it'll be a lot of fun working on it and finding out.
The writer is definitely into the repair portion of the typewriter hobby space and despite some of the FUD he's spewing for lack of experience, he seems on the right track. He's discounting his lack of experience in the general space compared to his experience in computers, games, and guitar repair which he's obviously spent time. At least he can rely on this scaffolding to move forward in the typewriter repair space. Most others won't have this experience at all and that makes it even more difficult.
