The Pin Spacing Drill Jigs are used to create the best spacing for the pins. These jigs are most often used on cracks longer than one inch. When repairing cracks in cylinder heads or any other short crack, pins are usually installed one at a time starting at the bottom, or one end of the crack, and working toward the other end, drilling, tapping and installing pins.
A Pin Spacing Drill Jig will help you drill holes on semi-flat to flat surfaces using the three step method. Drill the first hole free hand, place the locating pin of the jig into the drilled hole and drill the second hole. Next, move the locating pin to the second hole and drill a third hole on the crack. This is repeated throughout the entire length of the crack. Tap ...
A drill guide and tap extension kit includes a 4-inch long drill guide and handle, six 6-inch long split point drill bits and a 4-inch long tap extension. (Taps are not included; for L series taps and for C Series taps.)
The drill guide will help you start and drill holes at angles to the surface such as down in the valve ports of cylinder heads. Not only will you save time, but you will drill better holes and break fewer drill bits.
Each tap extension is designed with the same diameter as its corresponding drill guide. This assures that wherever you drill a hole with the drill guide, you will be able to tap the hole at the exact same angle with fewer broken taps and better tapped holes.
