Step 1: Solidworks: Create Custom Pieces

1) Begin by selecting the top plane and sketch a centerpoint arc

2) Set the radius of the arc to 4.5 inches

3) Select plane first reference → point second reference → line

4) Sketch a circle on a new plane

5) Select second sketch → swept boss/base

6) Sketch circle diameter 1.0625 inches → swept cut

7) Select the circle and curve the pvc on the inside

Step 2: Solidwork: Create PVC

1) Click the "Sketch" tab. Then click the "Sketch" button to start a new sketch.

2) Select the "Circle" sketch tool in the main toolbar. Click once on the origin to place the center of the circle there. Click anywhere in the drawing area to complete the circle.

3) Draw another circle. Place its center on the origin, then click outside of the first circle you drew to make it larger than the first.

4) Select the "Smart Dimension" tool from the main toolbar. Click on the outer circle and enter the outer circumference of the pipe into the box, and click the green check mark.

5) Click on the inner circle. Enter the inner circumference of the pipe into the box, and click the green check mark.

6) Click on the "Features" tab under the main toolbar. Select the "Extruded Boss/Base" feature. The "Extruded Boss/Base Property Manager" will appear on the left.

7) Click inside the box next to the "Depth" icon, which is a pair of red arrows facing away from each other. Enter the length of your pipe. Click the green check mark.

Step 3: Solidworks: Mating

1) When you open Solidworks, select assembly

2) Open the fitting and the pipe

3) Select mate on the top toolbar

4) Highlight the circular circumference of the pipe and then click and highlight the inner lip, then they will automatically mate together.

Step 4: Sub Assemblies

Step 5: Building Sub Assemblies: Base

1) Start by creating the outer part of the base. Use the 90 degree side outlets and insert the 7 inch PVC into both sides. Do this on all four corners of the base.

2) Use the t-joints and place one in the middle of each side, and insert the 3.25 inch PVC coming from both sides so that the tjoint is faced inwards allowing an opening to face the inside of the chair.

3) Coming in from the sides of the base is a square that will help for stability. Use the t-joints to insert the 3.25 inch pipe that will connect to the inner square.

4) Insert 2.5 inch PVC into the left and right of the 4 sided outlets. These t-side outlets will allow to make a smaller square within the base for more stability.

5) Now, insert pvc on the left and right side of the t-side outlets and place 90 degree outlets on the other end of the pvc. This will create four corners and a square for stability.

6) Coming up from the 4-side outlets in the inner square will be support for the seat, place 20 inch PVC in the top of each of the four outlets so that they rise upwards for seating support.

Step 6: Building Sub Assemblies: Seat

1) To create the main support for the seat, four pvc pipes will need to be inserted on the outlets from the base below. The legs will rise upwards and be inserted into a four 4-sided outlets.

2) Use the t-joints and place one in the middle of each side, and insert 7 inch PVC coming from both sides so that the tjoint is faced inwards allowing an opening of the t-joint to face the inside of the chair.

3) At the end of the pvc that is inserted inwards into the t-joint, 4-sided outlets will be placed which will allow to create outsells for the circle seat.

4) Next, bend a circle from pvc and cut in necessary places to allow to fit into the 4 t-side outlets. This is where one will sit.

Step 7: Building Sub Assemblies: Back/head Rest

1) Insert two 12 inch pvc pipes into the corners of the seat, these will rise upwards and become the supports for the back rest.

2) At the top of this pvc, insert two 4-sided outlets.

3) Insert 7 inch pvc coming inwards from the 4-sided outlet, and in the middle place a t-sided outlet.

4) Insert and 8 inch pvc into the t-sided outlet in a horizontal direction which will become the beck/head rest.

5) At the top, insert the other end of the pvc into a t-sided outlet thats facing downwards.

6) On the top of the back rest will be two t-sided outlets connected by four 3 inch pvc pipes. The outlets will be faced outwards and be used for the support in the back of the chair.

7) Connect the final sides of the back rest with two 90 degree outlets on the corners.

Step 8: Building Sub Assemblies: Arm Rests

1) Start by heating and bending the 26 inch pvc into a shape that would be comfortable as arm rests.

2) To bend pvc, use the mating and insert the pipe onto the coil.

3) As the pvc heats up it becomes softer. After 5 minutes of rotating the pipe for every 30 seconds, it will be hot enough to bend.

4) Remove the pipe and bend it how you want, then use a cold towel to cool it down and harden it up.

5) Once hard, insert the pvc into both 90 degree outlets on both sides of the chair.
