**Subject:** RFQ — Materials for hulusi (free-reed wind instrument) prototype build, 5-key family

Hi [supplier name],

I'm building a small family of wooden hulusi (Chinese cucurbit free-reed flutes) and would like a quote on the following materials. The five keys (B♭ / C / D / F / G) share the same materials list with quantity scaled per key. Please quote per the spec list below; substitutions noted are acceptable if the primary spec is unavailable.

| # | Item | Spec | Qty (one F-key build) | Qty (full 5-key family) | Acceptable substitution |
|---|---|---|---:|---:|---|
| 1 | Pakkawood round dowel | 1.0 in OD, 18 in length, straight grain, kiln-dried | 3 | 15 | Hard maple round dowel, dymondwood |
| 2 | Brass shim sheet (C26000 cartridge) | 0.008 in × 6 in × 12 in | 1 sheet | 1 sheet | Phosphor bronze 0.008 in (slight tone change) |
| 3 | Brass plate (C26000) | 0.040 in × 6 in × 12 in | 1 sheet | 1 sheet | Aluminum 6061 0.040 in (prototyping only) |
| 4 | Walnut bowl/turning blank | 5 in OD × 8 in L, kiln-dried | 1 | 5 | Cherry, hard maple, padauk |
| 5 | Beeswax (food grade, yellow) | 1 lb block | 1 | 1 | White beeswax (avoid paraffin) |
| 6 | Pine rosin (violin grade) | 8 oz | 1 | 1 | Commercial pine rosin (not bowmaker's) |
| 7 | Boxwood or buffalo horn rod | 0.5 in OD × 2 in L | 1 | 5 | European boxwood preferred |

I'd appreciate:

1. Per-unit and bulk pricing for each line.
2. Lead time and shipping estimate (US zip [zip]).
3. Whether you can hold stock for 30 days while I confirm the build schedule.

Thanks for your time. Happy to share the build documentation if it's useful — this is part of an open-source instrument-design project ([github.com/tonykoop/hulusi](https://github.com/tonykoop/hulusi)).

Best,
Tony Koop
