Design Summary
Wooden Hang is a handpan-inspired wooden idiophone / resonant-vessel hybrid. The packet recommends a replaceable top-plate hybrid over a bowl or cavity as the fastest honest first build, while still documenting split-shell CNC and segmented/stave alternatives.
Key Dimensions
| Parameter | Value | Status |
|---|
| Outer diameter | 18.0 in | design target |
| Overall height | 4.75 in | design target |
| Playing surface diameter | 15.8 in | derived estimate |
| Top-plate thickness | 0.200-0.320 in | experiment range |
| Bowl depth | 2.25-2.75 in | derived estimate |
| Gu diameter | 2.75-3.50 in | experiment range |
Prototype Ladder
| Prototype | Goal | Exit Gate |
|---|
| WHG-P0 | Coupon matrix | Repeatable pitch trend |
| WHG-P1 | Single-field cavity rig | One useful note plus measurable cavity response |
| WHG-P2 | Three-note sector | Manageable cross-talk and hand spacing |
| WHG-P3 | Five-note subset | Playable subset worth scaling |
| WHG-P4 | Full 9-note layout | Data-backed decision on family viability |
Manufacturing Notes
- Use stable hardwood or laminate systems first, not highly figured show stock.
- Keep note-zone geometry accessible from the underside.
- Track moisture content with every measurement session.
- Keep at least one replaceable top in the workflow until the geometry is earned.
- Treat the first full body as a measurement object, not a finish-line artifact.
Validation Requirements
- note frequency and cents error
- decay time
- cross-talk between adjacent zones
- body or port resonance
- moisture content
- structural issues such as cracks, buzzes, or sinking
Tooling Note
This packet includes generated binary companions for the design sheet, capstone deck, and print packet. The .pptx export came from pandoc, while the .xlsx and .pdf files were produced through local fallback export paths because the usual Python document libraries are not installed in this environment.
