My post the other day reminded me that I never actually posted this.
Once upon a time, as a supplement to my Milkman’s Workbench, I made what I called a “planing slab”. It was 6 feet long, 13 inches wide and about 2 inches thick (after several flattenings), with a Veritas Inset Vise on one end. It clamped to my dining table with angle iron, just like the Milkman’s Workbench. And now, it has reached its full potential.
I had always meant to add a cleat to the underside so it could function like a Japanese-style workbench. Nothing fancy, like the sliding dovetail shown in the source material. Just dado and glue. I used PVA, so I’m pretty sure it’s permanent.
The most important thing I’ve learned in this process is that the coefficient of friction on douglas fir is not significant. A layer of adhesive-backed sandpaper on the underside of the slab in front of the cleat or (better yet) on the tops of both sawhorses does wonders to keep the slab in place. A couple of F-style clamps holding the cleat tight against the front saw horse also work.
