Primitive Technology3 HN recommenders · recommended in 3 months, 2016–2018
demo · general · evergreen · 2016–2018 on HN
Primitive Technology shows building a cord drill from scratch and then upgrading it to a pump drill, using only primitive materials like a stone flywheel and cord.
HN people link it as a satisfying demonstration of hand-powered drills being made from nothing.

I definitely agree. I think this is the video you mentioned. I have watched it myself many times as well. "Primitive Technology: Cord drill and Pump drill" > ▶ this video
If you're interested in seeing someone make these take a look at this Primitive Technology video and the others he produces: ▶ this video Make sure you turn on captions to see descriptions of what's going on.
The guy over at the primitive technology vlog on YouTube just added a neat video of himself making a cord drill and a pump drill. ▶ this video
Oh the title sounds familiar, on the other hand no talk in mind .. great. ps: his fire starting example reminded me of this, ▶ this video (no supermarket involved though)
