Yes bot even the larger sizes may wobble, I've made tables out of pvc and iron pipe with flanges, and iron pipe is sturdier but pvc can work.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
