Kids like to haul stuff around. If they have their own personal tote they can pick up the little things and, maybe, carry them back.
Saw (crosscut or table)
Rasp or router & bits (optional)
1" hole saw
Ruler or tape measure
Ratchet & sockets
Vise or a good clamp and something to clamp to
1" x 4" x 12" (approx.)
4-3/4" #6 hex head screws
4 washers for screws
2 large coffee cans, plastic
Paint or varnish, brushes, etc. (optional)
Step 1: Making the handle
Cut the 1" x 4" so it is about 4" longer than the containers are high. Every tote needs a good handle. Measure 1-1/4" in from one end of the 1" x 4" and mark it. At the mark, measure in 1-1/4" from each side and mark on the first mark to make two X's. These X's are the centers of two of the 1" holes you will drill. Use the hole saw to drill just deep enough so that the 1/4" pilot drill just comes out the other side of the board. DO NOT drill all the way through.
Reverse the board and use the pilot holes as guides to finish the 1" holes from this side. This two-step process makes for a neater hole. Drill a third hole between the first two to remove more material.
Step 2: Final shaping of the wood
Use the rasp to remove the extra material still left in the hand hole. Also use it to round off the edges of the inside of the hole. Use the rasp to slightly round off the outside edges of the board. A router could be used for some of this step.
Sand the rough edges and surfaces. Paint or varnish as desired.
