Stair Balusters

With the edging installed and the railings varnished, we moved on to balusters. I bought three different kinds of wrought iron balusters to make up a pattern: plain straight, a swirling pattern intended to tie with the front door that we called “squiggles”, and “baskets” where several pieces wrap around to make a ball. Originally I was planning to put “knuckles” for these, little diamond-shaped bits along the straight length, but Sarah liked the baskets and they were cheaper than the knuckles, which made it an easy call. I worked out a pattern and approximate quantities to order, along with “shoes” (the little piece that goes at the bottom), epoxy, and an epoxy gun.

One of the “squiggles”

The installation process was to first map out where the pieces would go, such that they was never more than a four-inch gap (per-code) and yet they didn’t land on the bullnose part of the treads. This probably wouldn’t have been that hard with all straight and basket pieces, but the addition of the wider squiggles meant I had to adjust spacing. I wound up having to be flexible to get this to work, with each run of steps having slightly different spacing.

Dean came over to help with this project, bringing his metal cut off saw (of course he has one of those) which made the process go much faster than if we had just used an angle grinder. We started with the horizontal run along the basement stair opening (the stairs that don’t exist yet). All of the horizontal sections were much easier to work out spacing, since there’s no bullnoses to work around, but it was my first one so it still took me a while. I put a piece of masking tape down, worked out the spaces, and then drilled holes for each one. I used my laser level to determine where the top should go and drilled those too. Drilling these holes took forever, and I wound up getting a new spade bit for the rest of the project, which was dramatically faster.

The other reason the horizontal sections were easier is because all of the balusters were the same height. Dean was able to cut them in bulk and get the ends ground smooth while I got the holes drilled and then I started putting them in with epoxy. The epoxy dispenser worked pretty well, and there was a decent amount of work time. We taped all of the shoes up before we put the balusters in so that we wouldn’t forget them and they’d be out of the way until the epoxy cured. You can’t come back and put the shoe on later if you epoxy the baluster in without it, so this was important.

We worked our way up the first flight, which got the two longest stretches of railing complete that day, but that was as far as we made it. Dean was nice enough to come back not once, but twice this week to help finish the project. I needed to get all of the holes drilled in the edging going up to the attic and in the attic hallway before the carpeting installation so we didn’t get sawdust in our new carpeting, so I got those sections mapped and drilled in advance. The first evening we finished all of the horizontal sections, getting into a good rhythm. The second evening Dean was joined by both his dad and Dan, and the four of us were able to get through the three remaining sections of stairs, cutting, grinding, taping, and epoxying.

The last run we did we encountered a new problem. The balusters are 44″ tall since the railings are 42″ high but they need to pocket in. Somehow, on several of the steps leading up to the attic from the landing, because the baluster aligned with the back edge of the step where the baluster is longest, we needed balusters taller than that. To solve this problem, we added little stubs to the bottom of the balusters where it will be covered up by the shoe anyway.

The kids went around and removed all of the blue masking tape, and then Dan came back on Saturday and used an allen wrench to tighten all of the many, many little baluster shoes in place.

Stair Edging and Finishing

As I mentioned a couple posts back, Sarah took on the project of adding a hardwood edging to the stairs that go from the second floor to the attic as well as the attic hallway that overlooks the stairwell. Carpeting will cover the remainder. The first step was to add a piece of veneer plywood to each step riser using glue and a stapler, next cover the holes with Drydex (spackle) and prime the wood. I mixed up some regular drywall mud and filled in the corners where the risers meet the drywall sides of the stairs. I took the opportunity to patch some dings and dents, as well as close up the too-big vent opening in Emily’s ceiling. Some additional Drydex and sanding got most of these corners looking presentable, and paint will round it out.

Next was cutting mitered bullnose pieces to cover the tread edge. The rest of this L-shaped piece was filled with hardwood flooring scraps, which he fortunately have plenty of. Sarah cut all the pieces and glued and brad-nailed them all in place, with me assisting on a couple complex bits where they intersected the newel posts.

Sarah and Emily went around and spread wood fill into all the cracks. I had picked up red oak wood fill since it’s red oak flooring, but I’m a bit disappointed in the end result, because it’s much redder than the wood itself and stands out, the exact opposite of what you want wood fill to do. I would go with the natural color wood fill if we had a do-over.

After that, we got to sanding. We got some new power tools for Christmas, among them a cordless random orbit sander which got a lot of use in this process. A lot of edges needed more manual assistance from sanding blocks and folded pieces of sandpaper, but after many many hours, it was looking better.

I picked up TotalBoat Halcyon Clear marine grade polyurethane for the newels, railings, and edges, since we know they’ll need to handle a lot of abuse. After yet more sanding, we started brushing on the varnish. This… didn’t go as well. At a lot of the joints in the newels we started getting black drips. We’d wipe them off but then come back in a few minutes to find more, in some cases hardening in the varnish. This led to more sanding, more varnishing, and eventually we got most sections to look decent.

We spent a lot of time cleaning these up, and from the research I’ve done it’s most likely caused by a reaction with the tannic acid in the oak, but we can’t be sure. I don’t think it was a problem with the varnish, since no one else seems to have reported it and it’s very highly rated, but there are some other folks having general issues with oak finishing.
