FAE Pins and bushes

Picked one by one from a mixed channel. Transcript check: both title readers certain; 5 of 5 sampled certain picks confirmed by transcript, none failed. Channel rule: Include only build or repair videos that document machining a specific part, tool or fixture with narrated setup and process (e.g. vee blocks, die holder, Morse taper with sine bar, jig borer parts, engine build parts). Exclude quick looks, tool roundups, gift/kit openings without a build, and music-only clips with little explanation.
