It gets better & better. I forgot to add a short television clip Tamas Gyenes sent me; so here is that.
But I also received a short film about another Hungarian making one of these riven beech chests. Frederik Uijs (whose blog is here: https://frischesholz.wordpress.com/) sent a link of this 1955 film, that to my mind could almost be shot in 1555. Watch it & count the tools – probably less than 10. Axes, hammer, saw, chisels, that twybill-like tool, compass, drawknife, auger – not many more than that…astounding.
