Very nice. Isn't it satisfying to do that stuff? I've learned a thing or two over the years as well.
In my province, you can do just about anything, with a permit, and an inspection. Even electrical and plumbing. For the most part, common sense and care.
I learned from helping others, uncles and brothers-in-law, and books.
These days there are videos for everything, but I find that videos don't give you experience, or the hard knowledge gained of figuring things out on your own.
Small, scalable skills are just that... in the end it is all about time, cost, and having the health/energy to do it.
A bit of patience, a bit of planning, a lot of not freaking out when things go sideways.
Just like model building!!
