Step 1: Cutting

Here are the measurements that I used for this chair:

Minwax Gel Stain " Hickory"

Chair Dimensions: Arms, left and right

(4) -Top & Bottom = 30 inches

(4) - Front Back = 24 inches

Seat box

(2) Front & Back = 27 inches

(2) Sides = 22 1/8 inches

(5) Middle Support = 22 1/8 inches


(1) Top = 27 inches

(2) Sides = 18 1/8 inches

(5) Middle Support = 24 inches

4 and 1/4 inches x 6 in bolts 4- Washer 4- Lock washer, Lots of 3-inch screws

Mounting Bolts holes

Top hole in the arm rest is 7 inches from the back.

Lower hole in the leg is 15 inches from the floor.

Step 2: Prepping the Side Arm

To construct the two arms, I notched a section in the 2x4. This is only done for top and bottom. Refer to the 30-inch piece of wood. The notched-out section will seat the 24-inch piece of wood, which is for the front and back.

(See photo for a visual.)

On the opposite side of the notched section, mark two pilot holes for the screw. Do this on both ends of all the 30- inch 2x4.

Step 3: Assembling the Arms

Clamp and screw the 2x4 together, as shown.

You will end up with two identical pieces.

Step 4: Constructing the Seat

Assemble the seat with glue and screws. Rip a 2x4 in half so that it fits in the seat framing. This will be used to support the seat bottom inserts. (See measurements below.) Do not attach the middle inserts yet.

(2) Front & Back = 27 inches

(2) Sides = 22 1/8 inches

(5) Middle Support = 22 1/8 inches

Step 5: Drilling the Pass Through Bolt

Locate the front side of the box built in Step 4. The front should be measured at 27 inches.

Use a scrap piece of 2x4 to gauge where the leg should bolt though. (See the reference line I have marked in the photo.)

Find the center within the reference line and drill a 1/4-inch hole.

Next drill a 1/4-inch hole in the arm 15 inches from the ground. It's important to keep the hole as straight as possible.

Step 6: Attaching the Seat to the Legs

Insert the bolts and add the nuts.

Clamp, drill and insert the bolts for the chair back.

There is an additional piece of wood that site under the arm rest. This piece of wood holds the seat bottom to the back. It's supported with (4) 3-inch screws.

(1) Top = 27 inches

(2) Sides = 18 1/8 inches

(5) Middle Support = 24 inches

Step 7: Adding Top to the Back Rest

I used a biscuit joiner, because I didn't want to see screws here. Using screws here would have been fine, as well.

Step 8: Installing the Seat Support

Pre-drill the 5 middle supports. One screw on both ends should be sufficient.

Place them in the frame. (Tip: I used a piece of scrap wood as a spacer to keep an even gap.)

Pre (5) Middle Support =22 1/8 inches

Step 9: Completing the Chair Back

Now clamp, pre-drill and screw them back together.

Step 10: Prep Work

Remove the two arms and give it a good sand to clean up the rough surface.

Step 11: Applying Stain

1. I applied pre-stain conditioner, per the instructions.

2. Apply stain with a brush.

3. Remove stain with a rag.

4. Paint the two legs with high-gloss paint.

Step 12: Final Touch

After all the finish has dried, it is time to assemble by adding both of the arms.

Just inset the 4 bolts, 4 washers, 4 lock washers, and 4 nuts.
