After 20 years, I found my nailer was sitting wrong the whole time
Back in 2003, I was building face frames in my shop near Des Moines and always had trouble with joints that would pop open a few months after install. I blamed the wood movement, the glue, even the customer's humidity. Then one day a young helper asked me why my finish nailer was tilted back about 8 degrees when I drove the pins. Turns out I learned from an old guy who compensated for a bent tool, and I copied his stance without ever questioning it. Once I squared the nailer to the work, my joints stayed tight and I stopped getting callbacks. Has anyone else inherited a bad habit from a mentor that took decades to catch?
