A traditional way to make boxes is to make them all of a piece, and then cut them apart — this can be made easier by cutting a slot, and cutting through at the corners, but this results in losing the width of the slot (or more when a saw is used to finish) in height.
Couldn’t resist picking up a JointMaker Pro when they were recently on sale at Bridge City Tool Works:
Had to order screws from Lee Valley (which have finally arrived) — just need to decide on finish (will probably just rub down w/ walnut oil and beeswax) and which hardware to use.
This is why Sloyd should be a standard part of the educational curriculum:
Students may never pick up a tool again, but they will forever have the knowledge of how to make and evaluate things with your hand and your eye and appreciate the labor of others
