I made this box for my 4yr old son to keep things in. The wood is oak with walnut pegs and a walnut handle. The construction is pretty simple although there was a small problem with splitting putting in the square pegs into round holes. My test hole I tried it on was in the middle of a board, once they are on the edges it increase the possibility of splitting. Anyway, I only had to fix one split. The key seems to be keeping the size of the square peg as close as possible to the round hole. This was the first time making a top of this style and it’s secured with a brass rod for the hinge. It’s simple but has enough to keep it interesting.
