{"params":{"colorway":{"type":"choice","default":"brass-works","label":"Colorway","describe":"curated kit-coherent scheme, each carrying four of the kit's metals so no two touching pieces share a hue: brass-works is a polished brass coil off a brass turnbuckle on a dark-iron plate, with a bronze finger ring and an amber tell-tale; copper-rig drops the whole part a rung into bronze and copper on near-black iron, the warmest of the four; cold-steel takes every warm metal out for greys and whites and puts a blue sapphire in the bezel, the only cool accent in the set; gilt-ruby is bright gold on a leather-brown plate with a ruby","options":["brass-works","copper-rig","cold-steel","gilt-ruby"]},"plate":{"type":"color","default":"#4F5D75","label":"Anchor plate","describe":"albedo of the slab bedded on the back of the hand and the tray sunk down its deck. Dark iron by default: this is the largest dark mass on the part and its one cool hue, and its job is to be the land the brass turnbuckle, the four rivets and the amber tell-tale are framed against. Lighten it and the anchor stops reading as ironwork"},"spring":{"type":"color","default":"#FFD700","label":"Coil spring","describe":"albedo of the coil and nothing else, from its dead turns on the turnbuckle's shank to the wire diving into the socket on the ring. Polished brass by default and deliberately the BRIGHTEST metal on the part: the run of turns is what this asset reads as at any size, and it has to separate from the skin under it as well as from the dark plate it leaves"},"buckle":{"type":"color","default":"#B8860B","label":"Turnbuckle","describe":"albedo of the whole tensioner \u2014 the barrel, the tommy bar across it, the shank the spring is wound on, the clevis and its pin, and the standard under the barrel's belly \u2014 one knob because they are one shop's worth of the same metal. Brass by default, one rung below the coil it tensions so the spring stays the brightest thing on the hand"},"band":{"type":"color","default":"#CD7F32","label":"Ring and socket","describe":"albedo of the band round the ring finger's first phalanx and the socket standing on it that the coil dies into. Bronze by default, the same bronze the kit's other three tendons put on their finger rings, so all four read as one family when a hand wears more than one"},"iron":{"type":"color","default":"#2C3E50","label":"Lug and bezel","describe":"albedo of the two pieces of blackened ironwork: the lug bedded into the ring that carries the socket, and the bezel the tell-tale is set in. Near-black by default and the darkest tone on the part, which is the whole point of it \u2014 it is the frame that makes the amber read as a light rather than as a yellow spot"},"stud":{"type":"color","default":"#A9A9A9","label":"Rivets","describe":"albedo of the proud bolt heads down the plate's two rails. Steel by default, a clear step lighter than the iron they are driven into so each one reads by its own crown and the shadow round it rather than as a dimple"},"lens":{"type":"color","default":"#FFD166","label":"Tell-tale","describe":"albedo of the cabochon sunk in the plate's tray \u2014 the kit's one lit detail and the only zone this asset declares in `night`. It has a hex of its own so a consumer can light it by albedo without lighting the iron it is set in; nothing else on the part may ever be given this colour"},"hand":{"type":"choice","default":"left","label":"Hand","describe":"which hand the tendon is rigged for. Right is the exact mirror \u2014 the plate, the turnbuckle, the coil and the ring with it \u2014 so it lies on a tracked right hand's ring finger the way this one lies on a left.

The part is re-solved rather than scaled: the plate's underside is re-bedded on the hand's own lofted dorsal surface and its deck re-fitted as a plane through that, the ring is re-cut to the finger's real section, and the coil's whole line is re-run so every turn keeps its 1.5 mm off the skin. The made stock is identical at every value \u2014 the same 19 mm plate, the same 9 mm barrel, the same 1.2 mm wire \u2014 so the triangle count does not move with this knob","affects":"geometry","min":0.85,"max":1.3,"step":0.05},"knuckles":{"type":"range","default":1,"label":"Knuckle relief","describe":"how bony the joints of the hand underneath read, 0.3 smooth and 1.6 every knuckle a knob. It matters here because the coil crosses the ring knuckle at its closest: the line is solved against the mound at every station, so a swollen knuckle lifts the spring over it and the run gains an obvious arch, while a smooth hand lets the whole coil lie down along the finger","affects":"geometry","min":0.3,"max":1.6,"step":0.1},"reach":{"type":"range","default":1,"label":"Reach","describe":"how far back along the ring metacarpal the plate and its turnbuckle sit, and so how long the spring is. 0.78 pulls the anchor up to 26 mm behind the knuckle for a short busy coil of seven turns over a 32 mm run; 1.0 the reference, the plate 33 mm back with a 39 mm run of eight turns over the knuckle to the ring; 1.20 sets it 40 mm back toward the wrist on a ten-turn 46 mm run that crosses most of the back of the hand. The coil is REBUILT at the new length \u2014 it gains a whole turn at a time at a constant target pitch, and the plate, the barrel and the ring keep their own millimetres \u2014 so the triangle count moves with this knob","affects":"geometry","min":0.78,"max":1.2,"step":0.02},"tension":{"type":"range","default":0.45,"label":"Tension","describe":"how hard the turnbuckle is wound, which is the one thing this mechanism does \u2014 and what it moves is the SCREW between the barrel and the collar the spring seats on. 0 leaves 6.5 mm of screw showing with the spring slack, nine turns over a 38 mm run with 2.5 mm of daylight between them; 0.45 the reference, 5.2 mm of screw and eight turns with a 3.2 mm gap; 1 draws the screw in to 3.5 mm, which carries the coil's anchor back toward the wrist and stretches the same spring to seven long turns over 41 mm, gaps two and a half times the wire. The coil is REWOUND at each setting rather than stretched in the file, so the triangle count moves with it, and the pitch always opens furthest over the knuckle because that is the station that has to give when the finger closes","affects":"geometry","min":0,"max":1,"step":0.05},"bore":{"type":"range","default":1,"label":"Coil bore","describe":"the coil's diameter over the same wire. 0.80 is a 7.3 mm spring that hugs the finger and reads as a fine tendon; 1.0 the reference at 8.7 mm, half the finger's own width; 1.20 a 10.1 mm barrel on eight facets a turn instead of six, standing clear of the knuckle and dominating the run. The wire is the same 1.7 mm square stock at every value and the coil is REBUILT rather than scaled \u2014 it gains facets to stay round in millimetres, the turnbuckle rises to keep its shoulder clear of the plate, and the whole line is re-solved so every turn keeps its 1.5 mm off the skin \u2014 so the triangle count moves with this knob","affects":"geometry","min":0.8,"max":1.2,"step":0.02},"head":{"type":"choice","default":"tommy","label":"Turnbuckle head","describe":"what the turnbuckle is turned by, the one blob the eye lands on at the wrist end of the part. `tommy` is a 12 mm bar driven right through the barrel and standing proud on both sides, the reference and the widest silhouette on the anchor; `wing` a butterfly key of two blades standing 5.7 mm up off the barrel, the most obviously wound; `knurl` a plain knurled collar 5.9 mm across its waist, the flattest and most workmanlike.
