Restoring, or refurbishing drums is something you should 'evolve into.' You're doing it the right way, the 'organic' way, gradually accumulating knowledge/information, trying your hand at small repair projects, it's just the best way to get started. What'll happen is; over time, you'll find yourself taking on projects that are more and more complicated or demanding and -handling them-! That's what happened to me. Replace a strainer or a mount here and there, then I started filling and sanding a few small holes and cracks, then gluing up and clamping loose re-rings, straightening out warped or bent hoops, etc. On and on over the years slowly gaining in experience and confidence.
You may not have the space right now with your small family in full bloom, but maybe one day you will. I went from apartment dweller with not much room for hobbies as a young family man, to a homeowner a little later in life with a basement where I was finally able to set up a small work shop. Everything just came together at the same time, my level of knowledge and experience along with the place and the means to do it. It's nice to 'be ready' when your time comes. Keep in there reading, asking questions and taking on whatever small fix-it jobs you can do yourself. One day, not too far off in the future, you'll be ready to take on anything and you'll be set-up to do it. When you're 'there,' that's when this sh*t really gets fun!
