It is the point A lot of times that I share so people can see that it's doable in your garage with a minimal amount of special tools and special knowledge. This is very old technology we're playing with.
and you've touched down one of the strong keys and that's getting all the small things done that you can when your budget isn't allowing you to do other things. That way everything's prepared for when you can get an extra part or something. also staying at it bit by bit if there's something you can do everyday and I don't care how small and insignificant but just something like looking up a part, ordering a part, making a list of the things that you need to do next anything small. 5 or 10 or 15 minutes but just making it a constant push.
