Step 3 Assemble the Uprights

To complete the first upright, screw one of the riser pipes into the 3-way corner coupler of the bottom collar.

Then cut 4x more 1.5" sections of 1/2" diameter PVC pipe for use as spacers for the top collar and screw the riser pipe into to the 3-way corner coupler of the top collar as well. (shown almost complete below)

Now, build the mirror image of this first upright for use on the other front chair leg.
