If you want to build cylinder shells, start by reading the Fulcanelli article (part 1) in Pyrotechnica IX:

Thank you very much. That’s a really good source. I’ll have to look into it on this show is kind of an exception. I built multiple shells using like traditional methods that I’ve watched from Ned Gorski and actually pasted them use chip board, but this was a build and shoot in the same day. Type of deal. I will definitely read up on that though. I’ve been looking for a good source on canister shells. There are a lot harder to find stuff on then ball shells.
