@DaveG how do you find your Grex that one shown? Performance etc... All the info is appreciated.
What could you say about the nozzle? They say it's weak place of Grex brand.
I like the body of this AB, it's very convenient to hold. Your AB is side feed as I understand.
Vladimir, my Grex is actually an "A" cup, not side feed. I purchased it to see what they are like. I don't think I will be purchasing another .
Being an "A" cup, the intention was to use it for small, detail oriented work. The build quality actually looks pretty good. The finishes are all very clean, and blemish free. The parts seem to fit together well, and the brush feels fairly solid, and not cheap in the hand. It will also produce the type of detail that I was looking to use it for. Being a .2 set up, it will produce the same sort of detail and fine line work that one would expect from a decent .2 airbrush - the downside is that this particular brush REALLY makes me work for it.
I have not replaced the springs on either the needle chuck, or air valve, but I have clipped and compressed them, looking to improve trigger feel. It remains quite stiff, and tiring to use. I am pretty good at manipulating a trigger to feel the way I like, but this one has fought me pretty good. The stiffness of the air valve spring makes the trigger feel more like an on/off switch, and is difficult regulate. Once I am determined to make the best of the trigger, I start to see the detail that I want, and there lays another issue. There is something about the way the cup is shaped, or the way paint is drawn along the needle that is very unpredictable on this brush. I feel like I never know when paint flow might be initiated. The cup is also perhaps just a hair too deep, as there remains a lip where paint would be drawn along the needle, and it becomes difficult to clean out quickly. I have kept this one because it has shown some promising results, but I find it very tiring to use. I do plan on eventually working on it to see if I can make it more user friendly.
I have not had any issues with the nozzle, nor the needle thus far. I will try a decent macro shot on those parts to see if I can get some images for you to examine.
If it is a side cup you are looking for, I have been working on a "Veda" or "Fengda" type side feed like the other imports we have talked about in the past, and it has really started coming around. This one did take some work to get good performance out of - but it is really working well.
