Although I have not used drywall texturing guns for several years, I do remember them having interchangeable nozzles and also an orifice plate which you could dial to change the size of the orifice.
Well, now a lot of the guns that I see no longer have the orifice plate. In fact a somewhat inexpensive one that I just purchased does not have one. I do think that I can get the pattern I want just by changing the consistency of the mud, the air pressure, and the nozzle size but the various orifices were just one more adjustment that I had available.
What has changed over the years that the orifice plate is no longer needed?
