In Bill Ellis' restoration CD, he displays and uses a small cupped rotary file that comes from Rio Grande. Since I really care nothing about paying $10 for the catalogue (at the moment this is all that I'm interested in finding), does anyone know where I can purchase some of these?

I'd also be interested in hearing/seeing what you use to 'dome' your pins. I've seen so many scales displayed with immaculately domed pins. Please share your technique.
