Start with the original brand’s support or exploded diagrams, then broaden to architectural salvage, specialist hardware stores, online marketplaces, and community swaps. Verify materials, dimensions, and load ratings. Ask sellers for photos and measurements, and document everything so returns are painless and future fixes take minutes, not days.
A small caliper and thread gauge remove guesswork. Capture inner and outer diameters, pitch, and center‑to‑center hole distances. Keep a reference card of common standards such as M6, M8, #10‑24, and Euro‑screw sizes. Accurate measurements save cash, reduce returns, and ensure parts seat squarely and securely.
When originals are discontinued, fabricate responsibly. Model bushings, caps, feet, or trim clips, then print in PETG or nylon for durability, or machine replacements in hardwood and aluminum. Test fit, iterate, and share files with community libraries to multiply impact and keep legacy furniture fully functional.
