Introduction: How to Drill Straight Holes With a Hand Drill (Using Lego)
If you've ever tried to drill a straight hole with a hand drill you know how hard it can be. After screwing up drilling a hole three times in a row I decided to try to find a solution to the problem. This is what I came up with. The great thing about using Lego for this purpose is that you don't have to spend a lot of time making this jig; you just snap the pieces together and get to work. As with any project, be sure to use the appropriate safety equipment and be careful!

Step 1: What You Need:
- 9 4x2 stud bricks
- 3 2x2 stud bricks
- A right angle protractor (just to double-check the jig)
Step 2: Building the Jig
- Start by arranging 3 2x4 bricks and 1 2x2 brick into an "L" shape.
- Build up from that shape, covering the seams where the bricks meet on the layer below. You will have a 3 layer right angle when you're done.
- Use the protractor to make sure the jig forms a right angle.
Step 3: Using the Jig
- Hold the jig down against the wood the same way as in the pictures. Position the drill bit tightly in the corner of the jig and drill the hole.
- The bricks might get marked up a bit after a while; if that happens, just swap them out with new ones!
