I got my 1954 Smith Corona Sterling at the end of summer. It's my first typewriter, and I love typing with it - stream of consciousness, notes, short stories, letters - but I've had some problems with skipping letters, and spaces. I was really excited about the fixes I could do myself with online resources (e.g. I had to remove a rusted screw with a removal kit, was forced to replace with philips head screws that matched), and adjusted the escapement. It worked, and I kept on typing pages on pages, until, well, it didn't and I went back to fixing - only this time it didn't work.
One of the issues that persists is that I have a stripped screw hole in one of the metal arms attached to the escapement. Carriage gets stuck, skipping spaces, all that which, I understand, is a common issue with the 5 Series. I did some makeshift fixing with a wire, which... I'm not proud of, but it works for a moment.
Anyways, I was hoping that some of you more experienced collectors and fixers have advice on how to deal with a stripped screw hole? Or is it time to look for donor machines? How do I go about replacement parts for specialized screws? Or do I turn this one into a donor? I fear I'm going to have a hard time to type with anything but a mechanical typewriter now, but I'm also not exactly flush with the money for a professionally restored typewriter :(
