A sound of a tightening wrench (a bike repair kit) being spun around to produce its distinct ratchet like sounds. Foley fun: put to 25% of its rate and you get convincing metallic gear sounds, apply a tiny bit of reverb, maybe layer it with some screeching sounds from other users (or me, your choice) or a slow gate shutter to get a nice mechanical door opening sample.
