The Yankee driver is sort of like a predecessor to the cordless drill , designed to drive screws with less effort than turning a manual screwdriver by wrist action. The mechanism of the Yankee driver, which involves a set of spiraling slots in the shaft and a spring action mechanism, allows you to push the handle straight down to twist the shaft and drive the screwdriver bit mounted in the tool's chuck. There is a nostalgic appeal to the Yankee driver, largely because most of us recall a father or grandfather using one.
And it is fun to play with—an unusual tool with an interesting and rather ingenious mechanism. If you have one around the house, you or your kids might be a little fascinated by it as a symbol of a bygone era.
In its day, the Yankee driver probably was of great appeal to DIYers and craftsman tired of wrists that ached from manually driving screws. The problem is that the tool never worked very well. Or rather, it worked only under the most optimal conditions. The screw has to fit perfectly into the hole, and there can be no resistance at all—zero friction.
The slightest angle when driving the screw will cause the drive bit to jump out of the slot. In reality, the Yankee driver is only practical when driving or removing screws in metal. Wood—especially hardwoods—render the Yankee driver virtually useless.
And although in theory a drill bit can be chucked into the tool, using it to actually boring a hole is a laughable exercise in futility. The Yankee driver began its slide into obsolescence about the time that people realized the screwdriver bits could be chucked into power drills, and as cordless drills came into their own, the Yankee driver began to gather serious rust.
If you have a Yankee driver, it's time to move along with the times: Get a nice lithium ion 18V cordless drill. And leave the Yankee driver to your grandson to play with. DIYers seeking a very cheap and easy way to locate studs are often drawn to the cheap magnetic stud finder, purported to sense metal screws or nails inside the wall. This small tool that costs only a few dollars has a magnetic rod inside a plastic view window that is supposed to jump to attention as it crosses over a steel nail or screw in the wall.
As the argument goes, if you find the nails or screws holding the drywall, you have then found the stud. In reality, this tool works well in one situation only—on plaster walls where the construction used wooden lathe nailed to the studs. In this situation, there are many tiny nails embedded in each stud, and the tool has many targets to react to as you pass it across the wall.
The magnetic stud finder is very frustrating to use on drywall construction, as the magnet is so weak that it will react only when it passes directly over the head of a screw or nail. And because drywall is nailed at wide intervals, detecting a stud is mostly a matter of accident. This means that you have a lot of sweeping and dragging across the wall to find a fastener.
Find the same features and save a few dollars on Johnson Level's "Big Johnson" tape measure—it's a rebranded foot Big T. Schroeder's 5-inch Gripps ratcheting tap wrench is great for quickly tapping new threads, but can also be used as a compact T-handle screwdriver. This tap wrench has hardened jaws with a unique profile that creates a very strong parallel clamping action. The Gripps holder's ratcheting gear is a bit coarse when compared to full-size ratcheting screwdrivers, but the gear's larger teeth result in a stronger mechanism.
Three ratcheting settings include forward, reverse and manual high-torque modes. A deep fingertip groove and a knurled knob at the top of the tool are both nice touches that allow quick loosening and tightening of fasteners. Before Schroeder manufactured hand tools in Germany, it produced precision-turned industrial parts, a tradition that seems to have influenced the Gripps' design. The tap and bit holder is available separately or in sets with various attachments and accessories.
Learn from my mistake and secure the removable and easily lost T-handle to the Gripps body before throwing it into a tool bag. Ordinary locking pliers e. Vise-Grips often come in handy. But they're not that well-suited for twisting and turning applications.
