I just knew there was a good reason to hang onto that old office chair that's been in the basement for 15 yrs. Very creative, I like.
What did you use for the strainer material?
Got it at the flea market It's a grease fryer splatter cover, used in the kitchen. Cost $1. Tanks are found discarded.
Had to make a valve removing tool to get the propane fill valve out. Had to strap the tank to a tree to unscrew the valve.
NOTE: propane is heavier than air. You MUST purge the tank upside down to make sure the tank is empty. Or BOOM may happen.
I cut the tank with a chop saw blade, to make the funnel part. A 3/4 pipe may fit into a 1 1/4 pipe (may have to sand a little) Weld a bolt as a stop
I put a drain valve on the bottom of the tank to put the used oil into a transportation jug. The pipe unscrews from the tank. I made a plug with a tire valve to pressurize the tank to get the oil out.
I welded a bolt on the bottom to secure the tank to the chair wheels.
