Here is a material list I put together for this project.
I am a bit unsatisfied with the end costs, $49.79+tax.
Material Description QUA Cost Sub-Total
1" SCH40 PVC 24" Length 2 1.77 3.54
1" SCH40 T 2 1.29 2.58
1" SCH40 Elbow 4 0.99 3.96
1" SCH40 Cap 4 0.69 2.76
PVC Cement/Primer 4oz Pk2 1 6.99 6.99
Tennis Ball Yellow Can 3 3 3.99 11.97
4 Head Suction Cup (Northern Tool + Eqpt.) 1 17.99 17.99 Shipping Included this part
TOTAL (less tax): 49.79
Or you can go to Harbor freights for half the price. Up to you...
File comment: I used a Forstner Bit 1 1/4" (or 1 1/8" I don't recall) to drill the holes in the tennis balls. Burnt rubber smells. First I tried scissors and a knife but that returned sloppy results, not to mention dangerous.

File comment: Parts prepared. I used teflon tape but used a razor blade to cut and expose a portion of the suction cup hangle through the teflon tape. Once I put the PVC cement on there it bonded with the handle firmly.
