Here are the original instructions. I altered them a bit where noted:
{*I used 3/4" instead of 1/2" so it would be sturdier.}
(1) 1/2" x 10' PVC Pipe
(2) 1/2" 90 Degree Elbows
(2) 1/2" 45 Degree Elbows
(4) 1/2" 3-Way Elbows
(2) 1/2" x 2 x 2 Tees {I used 2 3x2 sanitary tees with 2 2x3/4 soc bushings}
I cut the 2" side of the tees to make a half circle that sits on the tubular frame of my pool. I have seen the pieces already cut before but Lowes only had tiny ones and Home Depot didn't have any. I'm not sure if they come in 2" but cutting a regular tee wasn't too bad. If you had "real" tools it would be even easier!
The top of the frame is a rectangle using (2) 10" pieces and (2) 14" pieces. About 12" x 16" when you add the 3 way elbows.
{I used 2-15" and 2-24" pieces to make a bigger square-about 17x25 total}
On the bottom piece of the front (2) 3-way elbows I used a 1 1/2" piece on each to connect to the 45 degree elbows. The diagonal pieces are 15" {mine were closer to 24" because when you put weight on it, it tends to bend down. Not sure o fthe exact length, I kinda eyeballed it} followed by a 90 degree elbow and connected at the bottom with another 14" {24" piece} piece to make the part that rests on the pool wall.
On the bottom piece of the rear (3) 3-way elbows I used a 1 1/2" piece on each to connect to the top of the 2 x 2 x 1/2 tees that I cut which then just rest over/around the top of the pool frame.
{For the top piece with the saying on it, We used a decorating piece we found at Target. We were having trouble finding a serving tray that was big enough. Hope this helps anyone that wants to do this!}
