I keep hearing it’s about 120 meters of 3-ply Danish paper cord per CH24 (Wishbone), but does anyone have the official figure from Wegner-era specs or a factory sheet? I’m lining up FSC-certified cord for a small run this fall and want the most durable, authentic match…
I checked with Carl Hansen last spring — it’s 120 m of 3‑ply per CH24, give or take a few meters depending on tension and splices. “small run this fall and want the most durable, authentic match…” — I’d go FSC Mix 3‑ply from Randers Reb and pre‑pull the cord through a dry canvas rag to even the lay; it tightened up cleaner and didn’t creep on me. Going natural or black?
I’ve re-woven a few CH24s with FSC 3‑ply; 120 m is right, but I always pull 130 m so I don’t have to splice mid-seat. In fall, let the cord acclimate overnight and use a cheap luggage scale in-line to keep your pull around about 10 kg — tension stays consistent and the length doesn’t creep. Small caveat: 4‑ply will cut the meters and feel stiffer but it won’t match the factory look — who are you sourcing from, @OP?
I’ve got a CH24 service sheet that says “approx. 120 m of 3‑ply, 3.5 mm, Z‑twist” per seat. Caveat: older frames with deeper kerfs or taller rails can add a couple meters.
Factory notes put it around 120 meters with 3‑strand, about 3.5 mm, “Z‑twist”; just double‑check your FSC cord is Z‑twist or it’ll try to unlay on the wrap. Practical step: pull 125–130 m for the first seat, then weigh and log the leftover to dial in your tension and humidity, @evelyn53 (like tuning a sourdough starter, but less tasty). Which FSC supplier are you leaning toward?
