Hi, I am in the middle of replacing the stairs in my house. The house was built in 1948 so I believe the stairs were carpenter made. The stairs I bout to replace them with were pre cut. I just had to make one cut to get them to fit. Here is my problem. I am a terrible nailer. I can't nail striaght to save my life. So I am thinking of either renting a nail gun or buying a cheap one. How long do the nails have to be? The steps are 1 inch. What is a Brad nailer? Would it be appropriate for the job I'm doing? I was looking at this nailer. Any help is appreciated.
