Stair Newels and Railings

In addition to the stair cladding, I also needed to do the newel posts, railings, and balusters. We’re going to have stained red oak newels and railings, and iron balusters with some spiral pieces to tie thematically with our front door. I did a bit of online research and started ordering the parts I needed. I got the newel posts from the same company that made the stair treads, we ordered balusters from a couple of companies, and the railings are from Home Depot.

I also did some research on how to mount these things, since no one wants a newel post that wiggles around. There are a few options, but I ordered some fasteners and set to work from the top down, figuring that since I needed to learn how to do this I didn’t want to start on the most visible and used section of the stairs.

I have a “half newel” that goes against the wall in the attic, which connects a horizontal railing to the newel post at the top of the attic stairs. Almost immediately, I ran into trouble, since the only wood behind the wall to anchor the half newel to was on the other side, meaning I needed screws longer than I had. I moved onto the newel post, figured out where that was going to sit, drilled a hole in the floor and screwed in the giant lag. I figured out the correct height for the newel if the railing is 42″ high and centered in the top portion, then cut the newel post to the correct height. You have to cut a hole in the side of the newel at the bottom and another one in the bottom. The newel fits over the lag bolt, then through side opening you put in a little curved piece and the nut. It’s a total pain to tighten the nut through the little hole with a wrench, and if your height isn’t right, you can’t get the wrench in or out. Finally you glue a little oak circle called a bung into the hole in the side. When we sand and finish, it should mostly disappear.

I had to notch cut the newel at the landing where it met the stair and the next challenge was attaching the railing. I bought “Zip Bolts” which are these little cams that fit into a hole in the bottom of the railing to screw down onto a bolt in the newel. These work well once they’re in and threaded, but getting them attached is a hassle. I also discovered that I shouldn’t tighten the newels down before I install the railing, since then you don’t have any room to fit the railing onto the bolts on either end, but I did have to tighten the newels down so I could get an accurate measurement of the railing length, so I wound up tightening, loosening, and then re-tightening the newels to get them situated. The angled Zip Bolts for the stair railings in particular were a frustration because they were so difficult to tighten into position that they would snap off and need to be carefully removed.

Progress continued slowly. I made a jig that simplified finding the spot on the newels to drill for the railing, and Dean helped get through a few more newels with his impact driver that sped up the bolts. Because I didn’t have room to get the attic railing in with the newel already tightened down and the wooden bung already glued in, I had to buy a variation of the Zip Bolt that had a little keyhole piece you screw into the newel. Then another cam-bolt in the railing can extend into the top, the railing slides into position, and then you can tighten it down. This worked eventually, but like everything else required a lot of trial and error.

The last two railings as I worked my way down were the first floor to the landing and then a horizontal railing on the first floor where the basement stairs will eventually descend. These were tricky because they were each two-part railings. Because the newel on the landing was aligned with the next run of stairs up to the second floor, it was set back from the front edge of the landing, meaning the railing had to change to horizontal before it connected to the newel. I worked this out by laying the railing on the stairs, cutting it to length and then attaching the short horizontal piece. Everything looked great until Sarah and I lifted it into position and it was short by a couple of inches. Some inspection revealed that I hadn’t accounted for how high off the step the bottom of the railing was: that needed to be the same height at the top of the railing where it connected to the horizontal piece. As a result, I’d cut the long railing too short.

Fortunately, I still had one long railing left for the horizontal run on the first floor, which was shorter. That meant I could swap the pieces around and not waste a very expensive piece of wood. The second go went more smoothly and I got the railing installed. The horizontal railing has a quarter turn on the end where it connects to the newel, so that was also a two-piece, but a bit simpler to fit. At least, it seemed that way until I realized the half newel against the landing column wasn’t square and I’d cut the railing down to the shorter side. I managed to get out of this by cutting the railing at and angle, and then fudging the end that ends on the stair newel off center by about a quarter inch.

With all the newels and railings installed, I went around with wood fill, sand paper, and a random orbital sander. I got all of the holes plugged with bungs, flush cut them, touched up with yet more wood fill and sanding, and it was pretty much ready to varnish. At that point we needed to switch gears to the second floor to attic stair edging I mentioned in my previous post, since it made more sense to do that and then varnish everything at once.
