So my brother and I made a squat rack out of excess 2x4s using a guide here http://homemadestrength.blogspot.com/2011/04/more-than-just-squat-stands.html
Haven't tested it but they are very stable (plus i can't squat amounts that would put much stress on it).

Was a day project, incredibly simple and cheap too (but we had a lot of the stuff already like the wood, screws etc, just had to get buckets and concrete). It was kind of fun to make, and the first time ive used concrete
