New to me18 521L. Are the poles and bases suppose to be this tight? They slide in about a inch then you have to really force them in the rest of the way. Then at the end of the day there is no way to physically pull them out without a pipe wrench. Should I grind either the pole or the base down a little. I cant see hauling around a pipe wrench all the time to twist them out. Gotta be a better way. Do they loosen up over time as they get leaned on?
