Okay so I took my own advise and picked up two yardsticks. I taped one with the tube to the stake I had in the center of the pool, then taped the other end of the tube to the other yardstick and held that. My wife read off measurements in the center while I read the measurement on the side and noted it down. I ended up with the following chart of measurements. Setting the middle to zero as the highest point, all other points were below that, ranging from 1/2 to 1 7/8" lower than the middle.
I'm not worried about the middle being slightly higher and outside the 1" spec, only the outer frame of the pool. So I re-referenced the measurements to the highest outside point, adding 1/2" to all measurements so the highest outside point would become 0". These numbers are seen in ( ) on the above drawing.
I then decided I needed to shave off 1/2" from the high point, and again re-referenced it to zero. When that is done, the following drawing is obtained.
Pretty close, but now that 1/2" is taken off there's a new high point 3/8" higher that the newly leveled point. So I have to shave off a bit more on the other side as indicated.
I may also throw a bit on the lowest points (-5/8 and -7/8) and compact it down well, after which everything should be petty level.
Inside the circle I'm not going to worry about leveling more. It may not be the world's flattest surface, but I don't intend to spend much time walking in the pool anyway...
I hope to get the final leveling done tonight. I'll be heading out to pick up foam and tape shortly. Tomorrow after church a friend is coming over to help and we hope to get the foam in place and the pool up!
Oh, and I'll be grabbing four 2"x12"x8' ground contact pressure treated boards. I'll cut into 1' lengths, for a 12"x12" pad for each foot. I won't dig any of the feet down, just put the 1" foam, cut it out around the wood pad, and throw the pool up on top.
Can't wait!
