A few days ago I decided to experiment with shink-pots (krympburkar). So far I like the technique and the end result.
I used an 1" auger to drill 3 holes, and then a chisel followed by a crooked knife to do the inside. I finished the outside using a cabinet scraper.
Getting the lid to fit is the most finicky aspect, the next time I'll try an easier technique, this one is friction fit and quite tight.
