How to build an adirondack chair

This diy step by step article is about free adirondack chair plans. In this article, we show you plans for building a basic woodworking adirondack chair. If you want to get the job done in a professional manner, we strongly recommend you to pay attention to the instructions described in the diagram. Add glue to the joints and align everything with great care at both ends.

In order to obtain a neat appearance, there are a few tricks you should know before starting your project. Therefore, you should countersink the head of the screws anytime it’s possible, otherwise we recommend you to toenail the wooden components. The basic idea is that the joints and the screws shouldn’t be visible, therefore you have to apply wood putty over the holes and smooth the surface with medium grit sandpaper.

Align the components properly before securing them with screws, otherwise you won’t get a symmetrical look. It is also important to buy quality lumber, making sure the slats are in a good shape, without cracks, twists or holes. After you build the adirondack chair, it is essential to round the exposed edges with a router and a 1/4” bit, otherwise you could injure yourself in the sharp edges. In addition, use a sander along the wood grain, to obtain a smooth surface. See all my Premium Plans in the Shop.

• F – 2 pieces of 1×4 lumber – 23 1/4″ long, 2 pieces – 1 1/2″ long, 2 pieces – 24 1/2″ long ARMREST

• 1 piece of 1×8 lumber – 6 ft
• 5 pieces of 1×4 lumber – 8 ft
• 1 piece of 1×3 lumber – 6 ft
• 1 piece of 2×2 lumber – 2 ft
• 1 1/4″ screws
• glue, stain
• wood filler

Tools

• Safety gloves, glasses, Miter saw, jig saw

Tips

• Smooth the edges of the wooden boards, with a router
• Pre-drill holes in the wooden components, before driving in the screws
• Countersink the head of the screws

• Don’t use lumber that is likely to crack or shrink
• Don’t over-tighten the screws to prevent the wood from splitting

Building an adirondack chair

Building side legs

The first step of the woodworking project is to build the sides of the adirondack chair. If you want to get a professional manner, we recommend you to mark the cut lines on the 1×8 slats, as described in the diagram. Use a circular saw to make the cuts and smooth the edges before going to the next step.

Installing the front support

The next step of the woodworking project is to lock the sides together, as described in the diagram. Drill pilot holes along the side of the front components and insert 1 1/4″ screws into the legs. Leave no gaps between the components and make sure the corners are right-angled. Add glue to the joints and remove the excess by using a damp cloth.

Attaching the front legs

Continue the woodworking project by attaching the front legs to the structure. Plumb the 1×4 legs with a spirit level, drill pilot holes and insert 1 1/4″ screws into the frame of the chair.

Fitting the seat slats

The next step of the woodworking project is to build the seat of the adirondack chair. In order to get a professional result, we recommend you to cut the seat slats out of 1×4 lumber at the right size. Drill pilot holes through the slats and secure them to the frame of the chair by using 1 1/4″ screws. Add glue to the joints and remove the excess by using a damp cloth.

Building the backrest

Building the backrest of the chair is a straight-forward process, but you need to pay attention to several aspects before getting the job done. Lay the 1×4 slats on a level surface and attach the 1×3 supports, as described in the diagram. Drill pilot holes before securing the supports to the backrest slats, in order to get a professional result. Add glue to the joints and remove the excess with a damp cloth. Mark the curved cut line on top of the slats and get the job done with a jigsaw. Place the slats equally-spaced, in order to get a professional result.

Fitting the backrest

Fit the backrest into place and secure it to the structure by using galvanized screws. Add glue to the joints and make sure everything is locked together properly. Attach a 2×2 support to the backrest and drill pocket holes at both ends. Insert 1 1/4″ screws into the armrest supports and leave no gaps between the components.

Fitting the armrest supports

Next, attach the armrest support to the frame of the structure, as described in the diagram. Drill pilot holes through the supports and insert 1 1/4″ screws into the front legs and into the support of the backrest. Place a spirit level on top of the armrest support, in order to make sure it is horizontal.

Fitting the armrests

One of the last steps of the woodworking project is to attach 1×4 armrests into place. Smooth the cut edges with sandpaper and remove the residues with a vacuum cleaner. Align the armrests with great care and secure them to the supports by using 1 1/4″ screws.

Fitting the armrest trims

If you want to enhance the look of the adirondack chair, we recommend you to build simple trims and to attach them to the armrest, as described in the image. Drill pocket holes along the side and top edges and insert 1 1/4″ screws into the adjacent components. Add glue to create a rigid bond between the components.

How to build an adirondack chair

After you build the adirondack chair, using our free plans, you should finish the wooden surface in a professional manner. Therefore, you should use an orbital sander to smooth the hard edges and the rest of the components.
