Thanks, EngraverHandHi, I cant remember what my compressor is at, but the regulator is always around 28 to 30 psi. It´s not too high and I like to work on details.. but I have that settings for my Classics and just use the same when I connect the BenchJewel. Probably it´s normal with a little more high, depending on what you are doing, but I like it that way.
