I'm currently renovating my interior staircase and have run into a tricky issue. I've replaced the old carpet and built a new frame with routed pine treads, but I'm stuck on drilling angled holes in the handrail to install iron balusters. I need these holes to be at a precise 40-degree angle, but I'm not sure how to achieve that accurately. I've watched quite a few tutorials online but still can't figure out a foolproof method. Any tips would be greatly appreciated!

One solid method is to create a jig that matches the handrail's angle on one end and sits at a right angle on the other. This way, you'll be drilling perpendicular to the wood, which helps keep the drill bit steady and ensures you hit that perfect 40 degrees.

That's a great idea! I’ll definitely give that a try, thanks!
