This one is from a 2×4.
Here’s a simpler project, another hat tip to BJ.
Carved from a single piece of 4×4, finished with danish oil.
This is the Borromean rings I’ve carved from a single piece of pine 4x4x4, finished with danish oil.
I got fascinated with carving this and similar “magic” objects after reading Bjarne Jespersen’s book Woodcarving Magic. I still find it a little mystical, perhaps because within any pair of rings none is connected to each other, but all together they are inseparable.
