    Hi, I’m Mark Jensen. I’ve spent years fixing things the practical way, usually in my own garage, driveway, or around the house. A lot of that started with simple jobs that turned into bigger ones. A noisy air compressor. A tool that wouldn’t start. A part that wore out faster than it should have. The kind of stuff that makes you stop, inspect, test, and figure it out. That’s what Tool Fixes is built around. I write about tool problems, troubleshooting steps, DIY repair questions, maintenance tips, and the everyday fixes that help tools last longer and work better. My goal is to make things easier to understand without making them sound overly technical. I like straightforward answers, practical advice, and explanations that actually help when a tool starts acting up. If a fix can save time, money, or frustration, that’s the kind of thing I want to cover here.
