Step 5Body measurements
Measure your belly height from the bed and add two inches (mine was 7”). Don’t cheat while doing this as you will regret it later.
Take the board length, subtract hip width+ and divide by 2. Mine 18”-16” = 2”, divide by 2 = 1”
Draw a line this distance from the left side of the particle board and another from the right side. The distance between the two lines should be your hip width plus three inches. The long PVC arms will be bolted to the board along these lines.
On these lines, measure down 1” from the top and up 1” from the bottom and mark four holes for the bolts.
Drill the four holes through the particle board with 3/16” drill bit.
Do not glue but push the 20” support elbows into the 1" PVC sticking out the base supports so that you have two lopsided U s.
Set the two U s side-by- side with the long arms inside. This is so the base supports extend away from your hips.
Rotate the long arms up to the approximate angle you think you will use. Mine is about 60º.
Hold one assembly on a flat surface. Measuring straight up from the bottom of the base PVC, mark the belly height+ on the top of the angled PVC with a Sharpie. This marks where the bottom of the board will go.
Repeat for the other assembly.
To make it easier to drill, rotate the long arms flat. Mark the centers of the long PVC 1” above the belly marks so the board mounting holes align with the board edge on belly mark. This is where the bottom bolts will go in the PVC.
For the mechanically challenged (like me), it’s easier to bolt on the two bottom bolts before drilling and attaching the top two. So drill the two bottom holes at the marks at right angles through the center of the PVC. Put the 8-32 bolts in the bottom two holes of the board and through the PVC. Screw on the nuts hand tight.
Rotate the PVC pipes so that the centers align with the lines on the particle board, so everything is square.
Put the drill in the top holes and drill through the PVC. Insert the other two bolts and nuts and tighten all.
If you have a lot of PVC sticking out above the board, you can cut if off an inch or two above the board. I use the extra inch to tie cables to. (See the picture below) Also if you happen to gain some belly girth, you may have to reposition the board upward.
Rotate the board up about 60 degrees and try it out. You should have a couple of inches clearance over the belly and a little room on the sides.
Making sure the long unglued PVC elbows are snug against the PVC and the tilt is to your best liking, drill two small holes in the middle of the elbow but not through the pipe.
Screw in two screws to keep the tilted assembly from rotating.
