If you wanted you could also use these in your own tiny Zen garden or bring them with you for a quick Zen fix anywhere that has sand.
Step 2: Measure Two Times, Cut Seven
The teeth are 1 inch segments of the 1/8 inch dowel. You will need 5 teeth.
The mouth(?) is a 2 1/2 in. segment of the 1/2 in. dowel.
The handle is a 7 in. segment of the 1/4 in. dowel.
. . . . Cut those pieces
NOTE: I HIGHLY recommend wearing protective glasses while cutting because. . .well, personally I like being able to see.
Step 3: Drilling the Teeth
Then, put 5 marks on the mouth that are 1/2 in. apart but start 1/4 in. away from either edge (see picture).
Use a 1/8 in. drill bit and (using a drill press if possible) drill the 5 holes at each intersection that you drew on the mouth.
Try to be consistent - If the holes are crooked or some are deeper than others, your rake might not look to pretty.
Step 4: Drilling the Handle
Get a 1/4 in. drill bit and again drill 1/8 in. into the mouth at the halfway point you marked earlier.
NOTE: I didn't bother drawing a line along the length of the mouth because I let it rest on the teeth while I drilled (see picture 2).
