Build steps and tools

  1. Measure the freezer

    Measure the outer length, width and body height, the wall thickness at the rim, and the compressor step inside: its length along the floor and its height above the floor. Measure your kegs with their couplers fitted. Enter them all; the model then shows how many kegs fit.

    Tape measure; a ruler across the rim gives the wall thickness.

    tape measureruler
  2. Cut the collar boards

    Mark the front and back boards at the full outer length and the two sides at the outer width less two board thicknesses. Cut them square. Cut the two hinge blocks only if your hinges need packing out.

    Square and pencil; a mitre saw, circular saw or handsaw for the crosscuts.

    squaremarking pencilmitre sawcircular sawhandsaw
  3. Join the corners

    Lay the boards on a flat floor with the front and back boards over the side ends. Clamp each corner square, pre-drill and drive the corner screws. Check both diagonals match before the last screws go in.

    Clamps, square, drill/driver with a pilot bit and countersink, driver bit.

    clampsquaredrill driverdrill bitcountersink bitdriver bit
  4. Bore the shank holes

    Mark the tap centres on the front board at the derived spacing and height. Bore through from the outside with a backing block clamped behind. Drill the small probe passage near the top of the right board.

    Hole saw or spade bit sized to your shank, drill/driver, clamp.

    hole sawdrill bitdrill driverclamp
  5. Line and finish the collar

    Sand the edges and seal the outside of the timber. Cut the foam lining to the listed sizes, fit it inside the collar and cut the shank holes through it. Keep the top face of the collar smooth for the lid seal.

    Sander and brush for the timber; ruler and utility knife for the foam.

    sanderpaint brushrulerutility knife
  6. Fit the collar and move the lid

    Clean the rim, stick the weatherstrip along it and run sealant beads beside it. Set the collar flush with the outside of the freezer. Unscrew the lid hinges, then fix them to the collar back board, or to the hinge blocks, at the same positions. Check the lid closes evenly all round.

    Screwdriver or drill/driver with a driver bit. Two people lift the lid.

    screwdriverdrill driverdriver bit
  7. Fit taps, gas and controller

    Fit the shanks and faucets, the drip tray on the freezer front and the gas manifold inside the collar. Set the cylinder and kegs where the model places them. Mount the temperature controller on the right board, run its probe inside and plug the freezer into it. Have a competent person check the electrical side.

    Spanners for the shank nuts are not in the tool list. No holes go through the freezer walls.

Before you build

Check the lid weight on the moved hinges, the gasket seal, condensation on the collar, CO2 safety and ventilation, and the controller wiring, which a competent person does. The model sets no serving temperature or gas pressure.

  • Check the lid weight on the moved hinges, the gasket seal, condensation on the collar, CO2 safety and ventilation, and the controller wiring, which a competent person does. The model sets no serving temperature or gas pressure.
  • The freezer, its lid and hinges, the kegs, couplers, CO2 cylinder, regulator, manifold and controller are reference shapes for checking the fit; they are not cut or bought here. The freezer is drawn white with rounded corners, feet, a badge and lights; those are drawing details. Faucets, shanks and the drip tray are drawn shapes, not products. Gas and beer lines and the controller wiring are not drawn; the probe hangs on its lead.
  • 5 kegs fit: 5 on the floor, with the CO2 cylinder on the step.
  • A keg on the step would need 54 mm more collar height.
  • The freezer sizes, hinge positions, foam and gasket thickness, tap spacing limits and the 10 mm gap around each keg are proposals. Measure your freezer and parts.
What the 3D model leaves out

The freezer, its lid and hinges, the kegs, couplers, CO2 cylinder, regulator, manifold and controller are reference shapes for checking the fit; they are not cut or bought here. The freezer is drawn white with rounded corners, feet, a badge and lights; those are drawing details. Faucets, shanks and the drip tray are drawn shapes, not products. Gas and beer lines and the controller wiring are not drawn; the probe hangs on its lead.

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