I am finishing up a remodel and need to mount some 4 1/4 inch baseboard. I am going through 5/8" drywall and the guy at home depot told me to get a 18 guage 11/4 inch brad nailer which I did. After thinking about it I realize that with quarter inch moulding that would only leave 3/8" of brad to penetrate the wall studs. I am thinking that perhaps I should be using a minimum of 1 1/2". So much for the $69 home depot compressor I bought! I want to get a quite compressor as I will be using it indoors and a gun. Should I go for a 18 G 5/8 - 2" or should I go for a 16 G 2 1/2?? From the reading I have been doing it seems that the finish carpenters generally feel that the 16 G is a waste of money and recommend getting a 18G 2" and a 15 G 2 1/2 " but I am not sure. Given that I do everything in my house but don't often do finish work, I would like to get one gun to start that will handle installing door and window trim, door stop, jams etc. as well as small ledgers for shelving etc. Is a 18G brad robust enough for these applications. If anyone has recommendations for a good compressor under $500 and a gun or two if that is the consensus to get me started I would appreciate it.
