In this video, This Old House general contractor Tom Silva explains how to repair a baluster.
Steps for Repairing a Baluster
- Set one-half of busted baluster in routing jig.
- Use a plunge router to cut a 3/8-inch-diameter by 1 ½-inch-deep dowel hole into the broken end of the baluster.
- Remove the first half of the baluster from the jig, insert the second half and rout the mating dowel hole.
- Squeeze glue into the holes in the balusters.
- Insert the hardwood dowel halfway into one of the holes.
- Push the baluster halves tightly together, making sure the parts are properly aligned.
- Install baluster in staircase balustrade, and secure it with 8d finishing nails.
