The manager at work found out about my new addiction, and commissioned me to make some ladder racks for the Gator we use to go from building to building. My first "paying" job. (we bartered for a nice drill press! Mmmm - okay!)
I made the rack in two pieces because it has a dump bed. I used 1" square tube x 1/8" for the uprights, and 3/4" I.D. black water pipe for the horizontal pieces. Mounting tabs made from 3/16" flatbar shaped to fit.
The job took 20 hours start to finish.
