I think i am going to use 1" square aluminum tubing and connectors to build the basic frame of my new platform. Right now i have a simple system made from 2"x2" wood frame and skinned with thin 1/4 or 3/8 plywood. Has worked great. But i want to change the height a little and i think the aluminum will be much better. I do have a few questions. Specifically will one companys connectors work with another companies 1" tubing? Also what thickness and what brands did people use? I just started looking into this. So any or all info about this will be great.
