Design note: Don't cut your crossbar pipe until you have measured!
- Connect the uprights to the chair legs and partially remove the top collars as shown in the first picture below.
- Cut 4x 1.5" sections off the 3/4" diameter PVC pipe for use as spacers in the cross bar assembly, and lay out the remaining parts. DO NOT CUT THE CROSSBAR PIPE YET.
- Make sure the 'T' couplers are pointing straight forward and measure the distance between between the inner edges of the 'T' couplers as shown in the second picture below.
- Subtract 1/4" from your measurement to determine the required length of 3/4" PVC pipe for the cross bar. Now that you know how long it needs to be, cut the crossbar pipe.
Design note: measure between the 'T' couplers instead of after you have the other couplers attached because it can be difficult to keep the crossbar "arms" created by the other couplers straight until they are held in place by the crossbar.
- Use 2x of the 3/4" spacers to connect the 'T' couplers on each upright to a 45-degree elbow coupler
- Use the remaining 2x 3/4" spacers to connect each of the 45-degree elbow couplers to a 90-degree elbow coupler.
- Insert the cross bar between the two 90-degree elbow couplers.
