It took me quite a while to relax and get comfortable with this tool. At first I was tense and applying to much pressure.My first few houses left much to be desired,but I stuck with it and finally the touch came to me and now its one of my favorite tools.I actually enjoy running angles with my mudrunner. You must be patient and not expect to run angles like a pro immediately, but if you stick with it,it will come.
Something that should be obvious that I had to learn was to relax the twisting motion as you approach an opposing angle and let the mud that's in the angle head deplete and finish out the angle,other wise you'll load up excessive mud and it will make a mess by dropping onto the wall and splat onto the floor. I have found that thin mud as you would use in your bazooka for taping ,works best for angles as well. If it doesn't squirt easily out of the mudrunner that your gonna end up fighting it and having poor results.
This mudrunner sucks, it will crown the angle. The mud is forced out at a higher pressure, it’s compressed by the angle head blades and expands . You can put a 6” knife on angle after it’s dry and see the crown and daylight going into angle. Which was not acceptable on commercial smoothwall. It’s cumbersome also, no one in our company liked them and they were discontinued being used
