We are currently in the process of building a backyard park and we want to build a metal rail similar to the ones youd find in a regular park. Weve been having trouble figuring out exactly what kind of metal pipe to use and how to put it 2gether (preferably without welding due to our lack of welding torches). ive got a shitload of cement so however we build it weel b able to cement the posts into the ground so we dont have to use the teepee method, any creative ideas are appreciated
