  • Confirm whether scanned planning dimensions are outside diameter, inside diameter, or finished head-seat diameter before CAD/DXF release.
  • Measure shell wall thickness, head clear diameter, cowhide thickness, rope diameter, and ring stock before treating family-spec.csv or cut-list.csv as fabrication authority.
  • Collect head-tension, shell-response, pitch, rope-stretch, and ergonomic data before promoting beyond L2.
  • Review CAD/DXF/design-table outputs against measured templates before any shop-release geometry claim.
  • Add sourced cultural/provenance notes before expanding public build instructions.

dundun — concept render

The dundun family has living Mande West African cultural context. This repo documents Tony's Morgan Drums stave-construction work and engineering process while keeping cultural claims modest until sourced review is added.
