2×4 Adirondack Bench Plans

Ovidiu 3 FavoriteLoadingAdd to favorites List YOUR FAVORITES GapDice RANDOM PLAN

This step by step diy woodworking project is about 2×4 adirondack chair plans. I continue the 2×4 series of projects, with this super straight-forward adirondack bench. This bench is sturdy, easy to build and it features a beautiful design. Make sure you take a look over the rest of plans to see alternatives and more projects for your garden.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day.

Continue the outdoor project by attaching the 2×4 slat to the front of the back legs. Drill pocket holes through the front component and insert 2 1/2″ screws into the front slat. Make sure the corners are square and align the edges. Add glue to the joints for a durable bond.

Fitting the front legs

Fill the holes with wood putty and let them dry out for a few hours. Smooth the surface with 100-200 grit sandpaper and remove the residues with a damp cloth. Apply a few coats of stain or paint to enhance the look of the chair.

    On the spacing for the backrest boards, why is there a gap of 1/2″ between the 2nd and 3rd board? Is this a typo? Should it be 1/4″ like all the rest of the board spacing?

    • Ovidiu at - Reply

      No, there is no type. It’s just you are left with 1/4″ which you can distribute it to several gaps to be unnoticeable.

    This thing weighs like 300lb. Build it where you plan on keeping it. Good luck.
