Every part in the build of this chair is critical and none more so than attaching the rockers to the legs. I have developed my own sequence of drilling and counter-boring and use four inch long specialised decking bolts for fixing the rockers to the legs, as opposed to using standard wood screws.
Each leg is in turn hand fitted to its respective rocker stack so that it passes a 1.5 thou feeler gauge test before drilling and applying the epoxy. Each leg/rocker joint is then dot punched to create a ‘hidden key’ to make for a stronger leg/rocker bond. Epoxy is then applied to both surfaces as well as the bolt shaft and then the bolt is inserted and tightened using a socket wrench. I prefer this method to screws because the bolts are bigger in diameter and a greater amount of torque can be applied with a socket wrench making for a much stronger joint. Because the shaft of the bolt is smeared with epoxy it sets solidly in place helping greatly to reduce lateral wood movement over time.
This is so your chair will be still rocking your grandchildren and great grandchildren to sleep.
