Step 1: Planing
Draw a plan for what size pieces you will need if making it a different size. This one takes. 2 5/8 pieces sides. 2 5x7 pieces other sides.1 7x7 piece for the bottom. 1 8x8 piece for the lid.
Step 2: Cuting the Wood
Cut the boards to the desired size following the plan. The wood I used was 1/2 inch thick but use whatever size you want. It may need to be planed down.
Step 3: Finishing
Sand the boards smooth then put on desired stain if you want. Then put on 3 varnish layers any shade you want. These steps only needs to be done to the side of the boards that will be facing in. if you want to do both sides now.
Step 4: Makeing the Top
make a hole for the lock make sure it is tight file if need to make bigger glue lock in on mine the metal lock bar had to be filed down do this if needed.
Step 5: Asembuly
Glue and nail the sides together and the bottom between the sides.
Screw on the hinges to the top first then the bottom.
Step 6: Making Lock Slot
rub some chaulk on the lock bar to mark spot chizel this out with a gouge or chizel checking it untill it is dddp enough be sure to leave at least 1/2 the thicknes of the board.if needed file the metal down some.
Step 7: Finishing Touches
If desired add a chain, string, slide bar. Or (leather like I did) find where you want it to stop opening hold it then staple it in. this keeps the lid from flopping over.
