Finally, after a good bit of sweating and refueling with coffee, the slab of top was done. But it’s not much of a bench without legs, now is it? One of the keys to proper bench building is the activity conducted thereon. A bench that is just right for planing will be too low for sawing joinery comfortably. In this case, the scrollsaw was to be used standing (though I may make a high stool later), and there was 9″ of saw to be accommodated. Do your measurements before you start cutting stuff out!
I started by sawing out the twin tenon on the tops of the legs. As these had to penetrate 3½” of slab top, the tenons were quite long. This necessitated using a slightly larger saw than I normally use to cut them out.
Once all of the rip cuts were done, I had to remove the waste. The shoulders on the outside of the leg (which are on the inside of the bench) were easy, requiring only a crossgrain cut to remove the cheek. The interior waste, however, requires a slightly different approach. I take an auger and bore out the majority of the waste at the root (which drops out that whole chunk in one piece), then clean up with a chisel.
It’s a little larger scale work than a lot of furniture making, but if you persevere you can congratulate yourself on a nice-looking twin tenon–
–then remember that you have three more legs to go. Oh, bother…
