The last sprinkler stand I made is still sprinkling, but dad needed a second one. The turned hubs of the first one have cracked from getting wet and drying out so many times.
I made the new one to be more waterproof-
Made of aluminum, delrin, and stainless steel.
I could have made the delrin inserts a press-fit, but I wanted them to be easily replaceable. They are each secured with a sheet-metal screw.
