Here are some more pictures from Anny from Belgium showing his tiny work. The dovetails shown are in 2.3 mm sycamore! The tiny chisel is a home made one. Blue Spruce also make some minute chisels for this type of work.
Below is more of the dovetailing kit, the reading glasses are a must at this scale.
James Krenov used to like having his cat in the workshop, although I'm not sure that's the most helpful spot to have a knap!
