Lawn roller made from 500 gallon propane tank

This lawn roller was made from a 500 gallon propane tank. The company my brother works
for sold me the tank for $100. The tank is 500 gallons and about 120" long and probably close to 48" high. I rinsed it about three times, filled it with water and started welding. I had to weld on spindles and cut out the old fittings and weld the holes shut. I left one 1-1/4 pipe fitting which I ground flush and tapped deeper. Then installed a flush pipe plug. This is the fill/drain. The spindles were make on a Mazak QT20 cnc lathe. The yoke was made from 2.5" sched 40 pipe and formed with a Hossfield bender.
