Accuracy is very important for the shelf to remain aligned and self supporting.
Step 1: Materials
I added a materials list per request.
1"x6"x10' pine planks 5 x $5 =$25
1"x10' EMT conduit 3 x $5.50 =16.50
3/4" conduit hangers (5pk) 2 x $2.75 =5.50
1" conduit straps (4pk) 3 x $2 =$6
spray paint $5
Step 2: Support Poles
Cut 1" EMT electrical conduit to desired length.
Step 3: Shelves
Cut wood planks to desired length.
Step 4: Drill
Drill holes in the longer shelves to accommodate one of the support poles.
Step 5: Sand
Smooth out any roughness on the planks with sand paper.
Step 6: Shelf Supports
Build two shelf supports for each shelf.
Step 7: Feet
Shape and glue feet for the support poles.
Step 8: Stain
Stain all the wood. You can follow with poly or other finish if desired.
Step 9: Hardware
The required hardware to support the shelves include tie plates, EMT 2-hole straps and conduit hangers.
Step 10: Prime
Prime the poles and hardware.
Step 11: Paint
Spray paint the poles and hardware. I chose hammered bronze.
Step 12: Tie Plate
Screw a tie plate to the underside of the junction of each shelf.
Step 13: Strap
Partially screw the EMT straps to the shelf supports so that they can slide over the poles. Screw the supports to the underside of the shelves.
Step 14: Fasten Shelves
Fasten the conduit hangers to the corner pole to support the shelves under the shelf holes. Tighten down the EMT straps on the side poles.
Step 15: Build
Start adding shelves to the poles. When all are in place make sure everything is in proper alignment and tighten down.
Step 16: Fill
Align the shelf with and fasten to the wall. Fill with books.
