Completed the marking out, now the fun starts. As I have posted before, on the base unit there are three different joint types plus the wedged M/T long stretchers.
The three types of joints are part of the genius of the original makers. Each of the joints is the simplest and quickest to make that is also strong enough for its job.
The top stretcher uses a brindle joint. a through mortise would add no strength and a brindle is much quicker and easier to make. The middle stretcher is a pegged through M/T with a single shoulder, again quicker and I expect stronger against racking than a double shouldered tenon. The bottom stretcher's only job is to keep the bottom of the base's legs from spreading. A lapped dovetail is perfect for that job and easier and quicker to cut than a M/T.
Tonight, tomorrow and for the next few days there will be lots of chisel and saw work and I expect a little sweat.

Hi Ken
ReplyDeleteThe stretcher also prevents racking. That's what the tenon shoulders do.
Steve,
DeleteYep that they do and triangles work better than squares.
