You will need:
1X3 ½ board. Length depends on your saw horse
1 ¼ “ X 5 SCH 40 PVC. Length depends on your saw horse
2 bolts at least 2 inches long with 2 washers and 4 nuts (I used 1/4 inch)
Hole saw 1 1/2"
chop saw or hand saw
Step 1: Uprights
Step 2: Uprights
Step 3: Uprights
Then add one of the wooden plugs
Next add a washer
Finish by adding two nuts. Put the first one on and leave about a 1/16 space between it and the washer. Put the second one on and tighten it against the first one. This will allow the plug to spin without binding up. Repeat for the other side.
