Master of the Pit
I put the bevel just on the pipe, hold a piece of plate big enough to cover the end and weld it on with the pipe standing on end, then take a torch and using the pipe as a guide, trim off the excess then grind it smooth. Saves all the time of trying to cut a circle to exactly match the end cap ( they usually are not perfect circles). Also, I like to install the end caps before cutting the door opening. Keeps everything lined up better.
