Ummmm, you don't need to take it that far. Just a skim pass of no more than 0.005-0.010 is sufficient. This generally trues the area around the hub bolts which is all that is needed. The issue with taking too much off of the hub is it locates the drum closer to the Brake Housing (Backing) Plate and it also affects the riveting process of the bolt due to the bolt shoulder being too long.
BTW, an interesting bit of 'trivia' that I learned awhile back. We have all used the term swage when we discuss installing new brake drums. Actually, when you study the A-1107 and A-1118 Ford print, it refers to the term 'Rivet' when it states to "Rivet over after assembly" on the print (see below). So when you look for the definition of 'swage', it is actually the special tool that is used to rivet the hub bolts -and not the procedure itself. Funny thing though, you 'rivet over' the rivet.
