Prototyping a tiny tool grinder (follow-up)

Thanks to everyone for responding to my questions. Most were positive about the synthetic voice experiment. In this video I only recorded the longer texts, and put the short ones as subtitles. And yes, there will be music!
Here I build a prototype tiny sharpening extension for tiny drills.
Music (royalty free):
Lloyd Rogers, On matters of consequence
Keys of Moon, After the rain
Claude Debussy, Arabesque No. 1. Andantino con moto
