V-BLOCK JIG

V-BLOCK JIGПодпись: SHOP TIPПодпись: Depth guides for drilling To bore a hole to an exact depth, use a masking tape flag or a depth stop block. If you are using the tape, measure the drilling depth from the tip of the bit, then wrap a strip of tape around its shank. Withdrawthe bit when the tape touches the stock. To use a block, sub- tractthe drilling depth from the length of the bit protruding from the chuck. Cut a piece of 1-by-1 stock to this length, then bore a hole through its middle. Slip the bit through the block and bore your hole until the block touches the workpiece. V-BLOCK JIG

Boring holes in cylindrical stock

To make the simple V-block jig shown above, mark a right-angle V on the end of a piece of solid stock that is long enough to hold your workpiece. Then, adjust the blade angle on your table saw to 45° and align one cutting line with the blade. Butt the rip fence against the stock and feed the board to cut the first side of the V. Reverse the piece and make the second cut. To use the jig, secure it to the drill table so the drill bit touches the center of the V when the quill is extended. Hold the workpiece in the V, aligning the bit over the cutting mark, set the drilling depth, and bore the hole (above).
