Iggy, I made mine by looking at others. The plans call for 3/4" pvc I used 1".
I just think it looks stronger and a more dominant support for our flag with a 3x5 flag on it then 3/4".
I used a 10' piece of 1" pvc pipe, one "tee", one "45 degree fitting", and "two caps", and "three eye hooks".
48" from the ground up to the 45 degree fitting, then a 6" off set to the "tee", the lower side is 24" with a cap and installed an eye hook at the end of the cap to hang whatever from it, the upper side where the flag is displayed is approx 42" with a cap.
I have seen where some people have added a "tee" on the lower side and installed a solar light so no matter which direction the flag is facing the light is shinning on it all the time as it should be at night.
