Balusters provide vertical support to make sure your stair railing and/or deck is as sturdy and safe as possible. These spindles help hold up the railing so people walking up or down stairs have something strong to hold onto. They can also act as a unique design element if they’re custom-made to suit a specific style or size requirement.

It is not recommended to cut or drill into LVL (laminated veneer lumber) beams. As major structural components of a home, their composite structure can be compromised by alterations, which can weaken them and lead to cracking over time. If you must make modifications to an LVL beam, it is crucial to consult a structural engineer or general contractor first. A professional can advise on whether it's safe and provide specifics on the appropriate bit size, depth, and directionality for any necessary drilling.

Many people, including professionals in the field, use baluster and spindle interchangeably to describe the vertical components of a railing (or technically, a balustrade). However, there are subtle or distinct differences, depending on who you ask. The most common interpretation is that spindles are thin or delicate versions of balusters.

If you don’t have a power saw with a blade where you can adjust the angle, you could use a miter box and hand saw to make the cuts. The miter box contains wide slots to support the piece of baseboard and other narrow slots to accommodate the blade of the hand saw. However, it’s tough to make non-standard cuts beyond 30 or 45 degrees when using a miter box.
