if you've ever sharpened chisels or plane irons, you shouldn't have to much trouble putting an edge on a razor. once you have set the bevel all the rest of the progression is just polishing. the more aggressive the material you used to set the bevel, the more polishing you will need to do.
i set the bevel on wet n dry paper and the use lapping film to polish, it's pretty idiot proof and cheap too.
