Step-by-step instructions for building a simple floating shelf
1
Measure and Mark
10 min
Measure your shelf board to the desired length. Use a combination square to mark a straight cut line across the face and edge. Double-check your measurement before cutting — measure twice, cut once.
Use a sharp pencil for precise marking. A dull pencil line can be off by 1/16 inch.
2
Cut to Length
15 min
Secure the board in a vise or with clamps. Using a backsaw, start the cut on the waste side of your pencil line. Let the weight of the saw do the work — do not force it. Keep the saw at a consistent angle.
Start with short, light strokes to establish the kerf before committing to full strokes.
3
Sand and Smooth
20 min
Sand the cut end and all faces progressively: start with 80 grit to remove saw marks, then 120 grit, then 220 grit for a smooth finish. Always sand WITH the grain, never against it.
Wrap sandpaper around a flat block for even pressure. Check your progress by wiping with a damp cloth — it reveals scratches.
4
Apply Finish
30 min
Apply mineral oil or your chosen finish with a clean cloth. Work it into the wood in the direction of the grain. Allow to dry according to manufacturer instructions, then lightly sand with 320 grit and apply a second coat.
5
Safety Check
multiple choice
Before using a backsaw, what is the FIRST thing you should check?
The workpiece is clamped securely
The saw teeth are sharp
The cut line is straight
The bench height is correct
Always check that your workpiece is securely clamped. A moving workpiece is the most common cause of saw injuries.
6
Mount the Shelf
25 min
Use a level to mark bracket positions on the wall. Drill pilot holes and install wall anchors if not hitting studs. Secure brackets with screws, then place the shelf on top and fasten from below.
Use a stud finder first. Mounting into studs is always stronger than wall anchors.
