Well, I know Rob Kampa does excellent edge work (probably the best in the country, in my opinion), but I wouldn't recommend doing that for an antique or otherwise collectible drum.

None of my vintage drums have "perfect" edges...and I wouldn't change a thing about any of them! But, I do also play a Magstar drum set that was modeled as close as possible to a Ludwig Jazzette as modern manufacturing methods would allow. Rob said that he even had to buy a special router bit to cut the vintage edge profile the "old" way...but he also added a bit of his own magic to the profile of those edges and I must say that the drums "sing" like no vintage Ludwig kit I have ever heard...so edge profiles definitely have aneffect on the sound...meaning "vintage" verses "modern" sounding. I find that most vintage drums with less-than-perfect edges have a sound related to their inaccuracies. Burger Kin

If bearing edges are not perfect in terms of thickness and flatness then even tension on all lugs will produce different pitches at each tension point. You can compensate for this by ear by tapping lightly at each tension rod on the head and adjusting so that the pitches match. This is time consuming but worth the effort.

Well cut edges make the toms sing, a la the Steve Gadd drum sound. I agree that cutting edges is frowned upon by purists but it will noticeably improve the sound if the old edges were imperfect. I've done this on my drums, I'm never selling them and they sound even better.
