Showing the strength of a splined joint
This for those who watched me making the moulded and mitred joint. A few weeks ago I experimented with the strength of the mitre joint to show the increased strength of my splined mitre joint. At both the Baltimore and Springfield shows, I made a hand cut mitred joint and jointed the mitre with two dovetailed splines let into saw kerfs from my dovetail saw. This cinder block is solid, not hollow, and so weighs in at around 40 lbs. You can see how uniquely strong the joint is. By moving the string along and increasing the leverage it eventually broke, but I am amazed how strong this joint really is.
