I made 10 one-piece Jumps in about a day using only a Hacksaw too... I went with 1 1/4" PVC for longevity. The Jump Cup Strips from Clean Run fit easily on this size. I ordered the Furniture Grade PVC from Costco. These come packaged in 2 5' pieces. I cut them in half for the uprights. I bought the Caps, 90 degree and 4 Ways using Furniture Grade PVC on Amazon after researching pricing. I did compromise with the White PVC for the Base and Legs buying it at Home Depot for $6 for 10'.
Materials for 10 Jumps

Thanks to Jeff Lyons, he recommended that I don't bother cleaning the writing off the White PVC. Instead, just make sure to have the Writing facing the Ground...

Have fun with it.
