Build steps and tools

  1. Measure the fridge

    Take out the shelves and drawers. Measure the outside width, depth and height, the inside width, depth and height, the door thickness and any freezer box. Measure how far the door liner reaches inside and enter it as the clearance to the door.

    Tape measure.

    tape measure
  2. Choose the supports and the pieces

    Pick a timber frame that stands inside, timber rails glued to the side walls, or bought tension rods; nothing is drilled through the fridge. Enter the widest and longest piece you plan to hang, the space you want between pieces and the drop between bar levels. The model counts the places.

  3. Cut the timber and bars

    Measure your battens and enter their section. Mark the uprights, cross rails, bottom rails and bar rails from the cut list and crosscut them square. Cut the bars to length, stainless rod with a metal-cutting saw and dowel with a fine saw, and smooth the ends. With tension rods there is nothing to cut.

    Pencil, square and a saw: hand crosscut saw, pull saw or mitre saw for timber; a metal-cutting saw for rod.

    marking pencilsquarehand crosscut sawryoba sawmitre sawsaw
  4. Notch the bar rails

    Clamp the left and right rail of each level together, top edge to top edge. Drill at each notch centre from the cut list on the joint line with a bit the size of the notch diameter. Pulled apart, each rail has half-round notches that line up across the fridge.

    Drill/driver, drill bit and clamp.

  5. Fit the supports

    Frame: screw each bar rail and bottom rail to the inside of its front and back uprights through pilot holes, lay the cross rails over the upright tops and screw down, then stand the frame inside. Glued rails: mark the rail heights on both walls and glue each pair level and opposite each other. Tension rods: twist each one out to the inside width at the bar heights and check it holds.

    Drill/driver, drill bit and driver bit for the frame; tape measure to mark heights.

    drill driverdrill bitdriver bittape measure
  6. Place the tray and devices

    Set the drip tray on the floor. Stand the humidifier in the back left corner and the fan in the back right corner, with the dehumidifier or second fan at the front left and the heater at the front right if you fit them. Lay the bars in their notches.

    No tools; check the clearances against the model.

  7. Route the cables

    Mount the controller outside on the hinge side. Stick the flat cable-entry seal in line with the door gasket on the hinge side, pass the sensor and device cables through it and coil spare cable inside. Hang the sensor from the middle bar in the place the model leaves for it, touching nothing. Plug the fridge and every device into the controller.

    Utility knife to trim the seal strip. A competent person checks the wiring and the ratings of every device.

    utility knife
  8. Check before use

    Run the chamber empty. Compare the controller reading with a separate thermo-hygrometer among the bars, look for condensation and water in the tray, and check the door still closes on the seal. Hang a loaded bar and check that its supports hold it. Take temperature, humidity, times, weight loss and nitrite use from a tested curing source; this model sets none.

Before you build

The curing process, nitrite use, mould management and the electrical safety of devices in a cold, humid space are on the builder; a competent person does any mains wiring. Check that the bars and their supports carry your load and that the door still seals over the cable strip.

  • The curing process, nitrite use, mould management and the electrical safety of devices in a cold, humid space are on the builder; a competent person does any mains wiring. Check that the bars and their supports carry your load and that the door still seals over the cable strip.
  • The fridge is a white reference drawn from your measurements, door open; its rounded top, feet, badge and lights are drawing details. Bars are drawn round; the rail notches are in the cut list, not cut in the 3D view. The fans are drawn standing on feet and the sensor on its cord; the humidifier, dehumidifier, heater, cable entry and controller are located boxes. None of these is a product shape. Hanging places are counted, not drawn.
  • S1 keeps wood out of a curing chamber because the damp air favours mould. The frame, rails are timber here; how you clean, dry and replace them is your call.
  • The frame stands on the fridge floor. If the floor steps up over the compressor at the back, the back uprights need cutting to suit; the model assumes a flat floor.
  • The model does not check the load on the bars. S1 notes that a large ham can weigh 25-30 lb, while sausages need much less.
What the 3D model leaves out

The fridge is a white reference drawn from your measurements, door open; its rounded top, feet, badge and lights are drawing details. Bars are drawn round; the rail notches are in the cut list, not cut in the 3D view. The fans are drawn standing on feet and the sensor on its cord; the humidifier, dehumidifier, heater, cable entry and controller are located boxes. None of these is a product shape. Hanging places are counted, not drawn.

Taking the model apart separates parts for inspection; it is not an assembly order.
