55 gallon bung size
Pretty simple question but I don't know the answer; what pipe thread size is the large threaded hole in the top of a 55 gallon drum? I think it's 2" NPT but it's been so long since I've used a drum for anything I can't remember.
I'm going to make a funnel by cutting a small water tank in half and welding a pipe nipple into the bottom of it, then screwing it into the 55 gallon drum bung to make pouring waste oil into it easier.

.Easiest conversion is to divide one inch by .0393700787402 than multiply it by two until you get 50.8mm (for the two inches).
To figure out the thread, put ink on your tongue, apply it to the side of the bung hole than press your tongue against a piece of paper. Measure the mark on the paper using a ruler to get the correct measurement (in stones).

I honestly don't know how a thread on the size of bung holes didn't go downhill. Figured it would at least turn political.
