some might call me CRAZY as i like to over build / do crazy idea's to build or fix stuff . so if you live life on the edge read on for this quick half day build project otherwise bye bye ......... 
1 part : 100lb propane tank real old
1 part : 1.5x1.5x3/16" wall square tube
2 part : 3/4" pipe
1 part : 3/4" pipe flange qty
1 part : 3/4" coupler
1 part : 3/4" plug
2 part : 3/4" cap
some

and here is what you get .
some of it might not be 100% square or perfect but who cares on this build for its 2-3 times a year use .
yes i vented it for over 2 years valve open and drained the oil from the bottom .
next step fill with water and try the roller out on the lawn after it stops raining .
