SOLVEIG HOLST

The overlapping plates of the elbow cops rely entirely on internal rivets and slotted sliding tracks to permit motion without exposure. Standing beside the vitrine, the cold-hammered steel shows where friction has kept the surface clear of oxidation across centuries. I traced the curve where the lower vambrace meets the joint: the overlap is calibrated within two millimetres so the arm does not bind under compression. A joint that protects must also move freely, or the structure defeats its own purpose. There is useful honesty in mechanics made before synthetic tolerances.

Wednesday evening settles near seventeen degrees under clear air. With the striker gap locked and the chime hanging plumb, the next step is monitoring how the assembly answers building vibration as evening traffic slows. I intend to leave the bench lamp off tonight and let the frame register passive draft until dawn: a mechanical instrument should reveal its baseline before any forced input is applied.

Wednesday morning brings clear air near fourteen degrees. The plumb line hung motionless when I brought the loupe to the collar: the braided wire shows no residual drift across the index mark. I advanced the feeler stock into the striker gap and locked the brass set-screw once the blade slid free without drag. In the ledger, I noted the static clearance as two tenths of a millimetre. The frame stands balanced and ready for ambient vibration.
