Steps:

1. Install bottom and top runners for the balusters to connect to. Attach 2x2 pieces of lumber to the existing wall that will support the bottom runner (figure A). Drill pilot holes to keep the wood from splitting and attach the supports to the wall using flathead square-drive screws. Wear safety glasses while working with power tools.

2. Secure the baluster rail to the supports with screws, and be sure to pre-drill pilot holes.

3. Add a second support using the same technique.

4. Measure for baluster placement. (For child safety, the Uniform Building Code calls for a gap of less than 4-inches. Check local codes in your area before installing.)

5. Clamp a level to the side of the first baluster and hold it in position. Mark the angle on the top and bottom for your cuts (figure B). Continue on up the stairs, holding each baluster in place, making sure it's level, and marking the tops and bottoms for cuts.

6. Carry the balusters out to the miter saw. Use a sliding T-bevel to set the miter saw blade to the correct angles for each cut (figure C).

7. Once all the cuts are made install the balusters. Drill pilot holes to avoid splitting and attach balusters using square-drive low-profile screws (figure D).
