In your May June issue you show a PRO TIP on page 42 that I lake exception to. When driv ing wood inserts. I've found that you need a jam nut on the drive bolt. Otherwise, the insert will screw out of the workpiece hole when you remove the bolt. I lere's how 1 usually drive wood inserts for my projects: After sizing the bolt to the inserts, I cut off the bolt's head. Next. I chuck (his bolt into my drill press, place a jam nut on the bolt, screw the insert onto the boh w ith the slot dow n. and then tighten the jam nut against the insert. To start the insertion process. I place the workpiece on the drill-press table, align the insert with the hole, and lower the drill quill. Next I hand-rotate the chuck to screw the insert into the workpiece hole. After I've driven the insen to the desired depth. I loosen the jam nut. and hand rotate the bolt out of the insert. Ron Hale, Joshua Tree, Calif. Thanks Ron. for calling the omission in the PRO TIP illustration to our attention. And yes. a jam nut should he used in fact we even go a step further and recommend using two jam nuts on the holt, as shown on the revised illustration at left, and a flat washer between the bottom jam nut and the insert. If you use a washer larger than the hole, it acts as a depth stop when it contacts the wood's surface. When using the drill press in our shop to drive inserts into workpieces. we apply just enough downward pressure to prevent the insert's threads from tearing the wood as they start into the hole. Using the drill press also ensures that the inserts will be driven in square an occasional problem when hand-driving threaded inserts. Your safety is important to us...We strive to present our plans and techniques as accurately and as safely as possible, and we try to point out specific areas and procedures that require extra caution. Bui becauscofthe variability of local conditions, construction materials, and personal skills, we can't warn you against all potential hazards. Please remember to exercise common sense and use safety measure:- when operating woodworking equipment. Don't attempt any procedures you're not comfortable w ith or properly equipped for. Sometimes, for the sake of clarity, it's necessary for a photo or illustration to show power tools without the blade guard in place. In actual operation, though, you should always use blade guards and other safety devices on power tools that arc equipped with them. Remember an ounce of prevention really is worth a pound of cure.
