Microsoft Word - Woodshop 101 Part 1 of 3

Step 6

We need to drill a hole through the end of the long boards and through

the handle. Figure 3 shows the placement of the hole in the long boards

and the handle. Drill the hole for the handle separate from the holes

through the long boards. Because the bottom of the handle is notched to

help catch the catapult arm there’s not much room for error in drilling

this hole, so pay careful attention to place the drill bit in the center of the

wood.

Handle

Now we can assemble the handle and the catapult arm. Just as we did

before, slide a washer over the bolt, insert the bolt then place another

washer on the end of the bolt, and finally the lock nut. The catapult arm

uses a 4 ½” bolt and the handle uses the 3” bolt. The catapult arm needs

to be able to move freely so just tighten the lock nut enough so that the

bolt doesn’t move.
