Step 1: Making the table legs
My table saw cannot cut a leg this thick without making 2 passes so I tapered them on my bandsaw. The bandsaw leaves a rougher finish and that looked even better on this rustic table. I made a quick and dirty jig to cut the legs which you can see in pic 3. The jig has a runner which slides in the miter track of the bandsaw table. Two hold downs were sufficient to secure the leg to the jig. I anchored an L-shaped block & a long block for positioning the leg on the jig. Once you've cut away 2 sides, the long block is no longer accurate and it becomes necessary to line up your mark on the bottom of the leg with the edge of the jig before clamping.
Because these legs were salvaged they had old screw holes in them which were filled prior to painting. In retrospect, it probably would have looked cool to just leave them. I lightly sanded the legs with 100 & 150 grit sandpaper which smoothed them without removing all the saw marks. One coat of chalk paint and 2 coats of clear Briwax was used to finish the legs. Briwax yellows the finish a bit which aged the paint nicely. Between coats of Briwax I sanded through the paint on some of the edges with 100 grit paper to show wear.
