When I decided to tackle a bookshelf project — which is finally under way with some choice walnut from Jeffries Wood Works — I came face to face with a tough realization: my comfort level with power tools. Now, don’t get me wrong, I’ve hung some heavy artwork, installed blinds, tackled a new dishwasher, wrestled a drum sander across my hardwood floors, re-caulked a bathtub — the list goes on and I’m always quick to brag.But I have to admit my skill level with power tools is firmly novice. In order to brush up, I went to our site’s best reference feature: Tools Central. There’s a great video series from licensed contractor Kayleen McCabe titled Essential Tools that highlights best power tool practices every homeowner should know. A key tool for my project is the cordless drill, which Kayleen demonstrates here.
