**Step 4 **
Screw the 1 x 2 x 1 block to the back end of the slider. Put an arrow in the saw clamp and make sure it's true with the torpedo level. Where the arrow nock touches the wood block, drill a 5⁄16-inch hole, 1⁄2 inch deep. Hammer the cable staple across the hole. This will secure your arrow nock.
