Quoted TextQuoted TextYeah-- By the time you buy a single action, use it for a few models, and wonder why you cant get the same feathered edge and "mottling" and fine lines that other modelers do, y!
Not true. My Badger 200 can get some very fine lines and mottling is a technique you learn to do with practice and a Badger 200 will do it just fine, same with feathering. You can control your air flow very easily with the Badger 200 with a simple turn of the rear element, the rest is how near or far you are to the object, pull away gently for gentle shading, or move in close and close down the air flow for tight lines.
I do agree a double action gun is the best bet, but your confusing technique with function. With practice you can make the simplest of guns preform excellent. A double action gun makes life easier but stating that a single action gun won't do the task is a fallacy.
Victor this little video will explain the guns and how they function. It's all about learning how to use the tool you have.
No one said it wasn't possible to get the same results with a single action brush-- I have several that I've used for a long time-- since the 60's in fact, including a Badger 150 and a 200. But, to get those fine lines with a single action you speak of you have to make many adjustments in air pressure, needle settings, paint viscosity and nozzle size. Sometimes it's guesswork and requires practice and experimentation before you put paint to the model to get those effects with a single action. It's time consuming and fiddly to stop, adjust, re-adjust and change the settings when you can just do it with the trigger on a double action brush. My Badger 150 and 200 are generally used for single applications now, Like base coats and touch up work.
***Yeah-- By the time you buy a single action, use it for a few models, and wonder why you cant get the same feathered edge and "mottling" and fine lines that other modelers do***
Yep, it sure was implied.
Don't get me wrong, I totally agree that a dual action gun is the way to go, but the most important aspect about using any gun is learning how to use the tool you have.
