I’ve always loved this detail and am fortunate to have installed it a few times before doing it for myself. It looks so simple but it takes sooo much time. I think I have between 40 and 50 hours on this little detail…but the outcome was worth it.
I machined the posts from 1/2″ x 2″ solid aluminum. The posts I have done in the past were are all 4x which is much easier to work with….but for interior I must prefer the aluminum I picked out. I got a deal on the aluminum using rough from the scrap yard. It takes a little time to polish them up but the outcome is brand new posts.
You definitely need a drill press and patience for the machining. All the holes must be perfect or else it will no doubt show. I used 4″ spacing per code. I got all the hardware from Hayn online, it is pricey but I couldn’t find this particular hardware anywhere else.
I topped off the posts with a ipe railing I milled down from a leftover rail cap. Its 1×2 and is plenty strong at 4′ on center. I love the look and I’m really happy with the result. I sprayed the finished posts with a clear matte poly for easy cleaning.
