One walnut slab, hairpin or welded steel legs, butterfly keys across the checks. Mostly patience and epoxy.
| Part | Qty | T × W × L | Material | ✓ |
|---|---|---|---|---|
| Slab Finished thickness after flattening — you'll lose ~1/4" total. Buy a 2" slab to end at 1-3/4". | 1 | 1 3/4" × 20" × 48" | Black Walnut | ☐ |
| Butterfly keys Quantity depends on your slab's actual checks. Cut them to suit what you find. | 3 | 1/2" × 2 1/2" × 4" | Black Walnut | ☐ |
| Item | Qty | ✓ |
|---|---|---|
| Kiln-dried walnut slab, ~48" x 20" x 2" (Black Walnut) $300–$500 depending on figure and where you live. This is 80% of the project cost. Ask for the moisture content — you want 6–8%. | 1 each | ☐ |
| Steel hairpin or flat-bar legs, 16" Bought, not made. A welded set costs about the same as buying steel and learning to weld. | 4 each | ☐ |
| Clear casting epoxy Fills checks and voids. Deep-pour formula if any void is over 1/2" — standard epoxy exotherms and cracks in thick pours. | 16 oz | ☐ |
| Walnut offcut for butterfly keys (Black Walnut) Contrasting species (maple) if you want them to shout instead of whisper. | 1 board feet | ☐ |
| Clear interior finish (hardwax oil or wipe-on poly) | 16 oz | ☐ |
| Sandpaper, assorted grits | 20 each | ☐ |
| Lag screws + washers for legs | 16 each | ☐ |
Overall cost: $$$$. Lumber varies by region, species, and season, so we give a band rather than a figure.
