The crowning achievement. A squat stand with a one man monolift.
The uprights are 2x3-1/4" wall tube with holes drilled for a 5/8" pin on 2" centers.
The upper crossmember is made of the same material as the uprights.
The base is made from 2x4 x 1/4" wall tube. The lower rear crossmember is 2x4-3/16" wall.
The monolift hook carriers are made from 3x4 x 1/4" tube and 3x3-1/4" steel tube, and 1/4" thick 135 degree gussets. I used hard plastic leaf spring inserts to for a wear piece between the carriers and the uprights. They are installed into 9/16" holes that I drilled. The two pin holes on the carriers are drilled on 3" centers which gives me the ability to adjust the height in 1" increments.
The monolift hooks are cut from 1" plate and sleeved with 1.5"dia.-1/4" wall tube to allow me to use a 1" x 3/4" bronze flanged sleeve bushing. The hooks are mounted to the carriers with 3/4" shoulder bolts. The hook belly is lined with UHMW channel to prevent bar damage.
The whole stand is assembled with 5/8" bolts.
The bar shown is a Troy AOB-1200B bushing bar with snapring retained collars.
The bench is something made for a fellow powerlifter I used to work with.
