Introduction

There are really just three steps involved in replacing a broken spindle: remove the old one, find a replacement, and fit it in. These tips will help the process go smoothly.

How to Replace Stair Spindles

It’s true: The banister spindles on your old stair rail weren’t installed with the notion that they would someday need to be replaced, but don’t be intimidated—they can be, even if the spindles are trapped in holes at the top and bottom.

To find a matching banister spindle, start local. Try the lumberyard closest to your house. There’s a good chance the builder of your home purchased it there. If not, the folks working there may know where it came from. otherwise you could try an online source. If you can’t find a new one, you may need to have one custom made by a local wood turner.

Step 1

Yank out the broken spindle

The first step to replace stair spindles, is removing the damaged spindle. If the spindle isn’t completely broken in half, finish the job with a saw. Then persuade both pieces out of their respective holes. Wiggle while you pull and make sure you don’t break off the end of the banister spindle in the hole. You may need a big pair of pliers to do the job.

Step 2

Deepen the upper hole

Next, find the proper size spade or Forstner bit, and overdrill the top hole. Be careful not to punch all the way through the rail. Mark your bit with masking tape if you have to. Overdrilling the hole in the handrail will allow you to push the new spindle up into the railing and then back down into the hole at the base.

Step 3

Test the fit

You may need to cut down the new spindle to make it fit, but mind which side you trim down. If you cut too much off one side or the other, the shape of the replacement spindle may not line up exactly with the existing banister spindles.

If the old spindle was glued in and the bond is still strong, you may have to cut the damaged spindle out flush and bore two new holes. If you think that the damaged spindle may be held in with a brad nail, don’t use your most expensive Forstner bit to bore the new holes.

Don’t go for the glue until you’re sure the new spindle fits. Insert the upper end, then drop the spindle into place.
