Well, im glad my hunch that those curves weren’t cut ‘freehand’ was correct so i dont have to nurse a sense of inferiority.. Sounds like your process is pretty good considering what you’re working with. I wonder if you can put a tiny bearing on a plasma cutter tip the way you can put a bearing on a router to follow an edge? Might make it smoother, but conductivity of the bearing is probably an issue.. lol.
As far catching the fab station on fire, it gets what it gets! Thats the beauty of owning/building all your stuff vs borrowing, renting, or paying through the nose for new.. You dont HAVE to care any more than you want to.
