This was my first pandemic project! First drums I've made from scratch, too. Made from fiberglass model rocket fuselages, with Tama hoops, DFD lugs, and Gibraltar mounts so I can mount them non-parallel. 13.5, 15.5, 17.5, and 18.875 inches deep. I'm shocked at how much tone these things have!
I've got two more shells that were leftover of the full-length tube I purchased, then had cut to length, so I'm going to have two more finished before too long, but I will most likely sell those.
