I am using a file mounted at a 35o angle into a delrin block to bevel these frets and get them ready for "dressing" which is a fancy name for deburring. This is hugely important since neglecting to properly bevel and dressed frets can cut a players hand up as well as look like ASS.

Be careful when doing this that you don't make the beveled edge a mile wide. It should only cut about a 32 of an inch into the fretboard. Also don't bash the headstock with the file.
