I purchased the Infinity CR+ a couple of years ago, and to be honest, have never really been all that crazy about the brush. Don't get me wrong, it is beautiful - incredibly well made. Small little things I could look past if the brush sprayed well - but my sample has been a bit ambiguous to use. The paint initiation is ambiguous, and at times I need to draw the trigger way further back than others to get paint flow started. It also has a tendency to produce fine bubbles into the color cup while painting, and has not been exactly stellar at working on small details.
I recently purchased a Grafo T1. They too are now made by H&S, and share many of the same parts as the Infinity. The Grafo has been absolutely wonderful. At some point I decided to switch the heads on the two brushes, because I really like the Crown set up on the Infinity. I just feel like it tapers down smaller, and exposes more of the work area while painting. Only problem is, that when I switched out the parts, the Grafo did not work as well as it did with the original head on it. At the same time I tried the Grafo head on the Infinity, and found that the brush responded much better, and was a pleasure to use.
Time to figure out what is different! I ordered another complete Crown head assembly (mine are all in .15) for the two brushes. So, Needle, Air Cap, Needle Cap, and Nozzle come in a small plastic tube, complete with nozzle base seal. This brand new set up did not work as well as the originally installed set up on the Grafo.
Using Golden Hi Flow shading gray, the line was OK, but nothing to write home about. Paint initiation was a bit ambiguous, and I felt like I was having to pull the trigger further back at times to get things going. I also saw times where I had a blob of paint at the beginning of paint initiation, and then could close the needle a bit, before getting a smooth line. The original set up is much more precise, and easy to use.
When I put the original head back on, using the same paint, I could pull a thinner line, that was also darker in color.
After some part switching and testing, what I have found is that it is actually the nozzle that is causing the difference in performance, and not the head assembly(s). For what ever reason, the nozzle that came as standard in my Grafo is magic compared to the two others that I now have.
In the photo below, I assembled the brush with the Crown head set up, with one nozzle. Photographed it, and then assembled it again with the other nozzle to photograph it again. I then stacked the photos to confirm what I thought I was seeing - the needle sticks out further on the nozzle that works better than it does on the other. The needle in the photo's is the same needle - only difference is the nozzle.
The bottom line is, that the nozzle set up on the Grafo allows me to paint thinner, more consistent lines. In addition, paint initiation is much more predictable and smooth. Now, how to find more nozzles like the one on the Grafo?
I ordered two more .15 nozzles to test, and will come back in an add to this as I have results...
