ive seen people take a strip of matching wrap and glue to the drum covering the seam and rivets. it made the drums looks a lot better. Ludwig started riveting when they had problems with the wrap shrinking I think. I believe this was only done during the 6 ply period.mike
I knew they used rivets for shrinkage purposes,however, with this being the case, why does my early 1980s Ludwig 8X14 Colosseum snare have rivets on the METAL wrap. I always wondered about that one.
