My first try at setting the bevel
To the OP, if you're so inclined, you can easily measure the bevel angle. Search Google for the bevel angle calculator, it's an excel sheet with a formula. The width won't matter, as long as you're hitting the right angle zone.
Ink the bevel, as Euclid suggested, that will help you a lot.
Magnification... yes, you can get a cheap magnifier and it will help some. They are junk though. Ever since I got a 10x Bausch&Lomb loupe, with no lighting or anything, I never reach for anything else. It costs more, but it's well worth the price. Note that those numbers advertised on cheap magnifiers (30x, 60x etc..) are a lie. 10x B&L will tell you everything. The next thing you might want after that is a $500 microscope.
