Tonight I assembled the the heater spear for 55 gallon drum. I used a 1"x1"x3/4" Tee fitting with the top element from my water heater. A 2"->1" bushing will allow it to be connected to the drum. The 3/4" opening is on the side so that you can heat and still use the hole to move oil/BD through. Thanks goes out to all the people at the infopop forum for already making it as it wasn't my original idea.
