Because of my familiarity with them, @Rick Martin sent me his Master G86SB to have a look at, to see if anything was amiss that would cause some of the trouble he was experiencing trying to learn using it.
Rick, to help ease your mind, I will say - yes. I will also tell you that it is already working like a charm
The first thing I check on these brushes is nozzle alignment. The easiest way for me to see them is to just photograph them using a macro lens, and then zooming in on the image. Ricks sample is significantly off center -
Rather than mess around trying to center it up, I opted to reach for the parts bin, and see what I might have to help the situation -
I checked a few spares the same way, by photographing them, and doing a visual check - I chose one to test with.
Mounted, it looks much better than the first one - but does it work?
Well, yes, it does. I used Golden High Flow straight from the bottle to test. It will pull a line easier, and finer than the first head - but, we are not done yet. I am going to press a bushing into this brush body (for Rick), just like I did on my own, so that Iwata color cups can be used. I tested the brush simply by adding a few drops of paint into the side feed opening to get a feel for what it was going to do. The original head was indeed erratic, and would produce a line that was taller than it was wide, due to the nozzle being so far off center. The new one is much better, but I will see about tweaking the center just a tad more to keep it dead on. I'll check in the lathe in the morning to see where to go from there.
Another issue I found was that the seal around the base of the head assembly was leaking badly, which never helps anything. Snugging with soft jaws did not cure it on the original head, but worked fine on the replacement. I would try to inspect the original seal, but it is really not worth the effort...
