A simple shelf for a workshop
Step 1: Material
You need a long board for the back and short boards for the shelf
Mark the position for the short boards where ever you want
Step 2: Make Your First Cut
The height of the saw blade is 1/4 of the width of the long board
Step 3: Add a Spacer
and make your second cut.
The width of the spacer = the thickness of your short boards minus the thickness of your table saw blade
Step 4: Remove Material
make so many cuts you need
Step 5: Adjust the Tablesaw
The height of the blade should be the thickness of the long board
Step 6: Make a First Cut in the Shelf
You can calculate, where this cut is to make but it is not important. Somewhere near the centre is good.
Step 7: Make a Second Cut
Use a 2nd spacer
The width of this spacer = the width between two opposite cuts of the long board minus the thickness of your table saw blade
Step 8: Remove the Material Between the Cuts
Repeat this steps for any shelf.
Step 9: Put the Shelfs on the Long Board
use a mallet if necessary
Step 10: Drill a Hole
or 2, if you want.
Step 11: Screw It on the Wall
and fill it with stuff.
