Check our materials page for a list of materials and tools needed.

 

Lay out blocks to build on if uneven surface like our back yard.

 

Sides: 2 x 12 x 8: Cut two to 8' and two to 44"

(44" size reduces the width of bin to allow for overhanging lid to save on handle costs)

Lay 44" pieces inside 8' pieces

Set 3" screws in 8' end with hammer to start them

Glue seam (liquid nails)

Square bin

Screw

 

Mark with pencil, which is front of bin (nicest wood showing)

Square the box

Square the plywood

Glue around seam (liquid nails)

Screw 2" screws every 8" all the way around bottom

 

Legs: 2 x 6 x 10, Cut 30" and 30" and 29 ½ and 29 (makes one low corner for downspout)

Place legs on the sides of the bin

Mark lowest front corner with pencil

Screw in with 3" screws, 4 screws each

 

Hole for downspout: Use drill bit for size downspout tubing and drill

Use Propoxy 20 around bottom to hold in place

 

Caulking: Use silicone caulk around inside seams of box

 

Laticrete: Wearing latex gloves put a layer of laticrete on bottom and about 5 inches up sides

 

Lid support: Cut 2 x 2 to 44". Measure bin to 4'. Put glue on ends then screw to secure in place

 

Heat Cable Placement: Turn bin over and place heat cable on bottom. Hold heat cable in place with

little U hooks or very carefully with staple gun. Place 4 x 8 x ½ inch insulation board over heat cable

and carefully hammer in roofing nails to secure insulation board.

 

Lid: Measure and mark 4' on the 4 x 8 x ½ then cut carefully to make two opening lids. Use

sandpaper to soften cut edge

 

Hinges: Measure 12" from each side. Screw hinges on top first then sides
