In my experience, it’s the joints in the handrail that people really scrutinize. They are easy to see, and if a misaligned joint doesn’t catch your eye, your hand will eventually find it instead. Here’s a tip to help keep those joints between handrail sections, such as the intersection between the easing and the rail, aligned properly.
As shown in the drawing, I set two little brads into the rail, and then clip off their heads, leaving pointed brad ends above the rail bolt. Now when I draw the two pieces together by tightening the nut on the rail bolt, the handrail sections won’t twist.
