Sandpaper

While we who build wooden things do get to cut and clamp, and design, and glue, mostly what we do is sand things.
The lowly and ever important sandpaper is the most used tool in all.
We glue something together, then we sand away all traces of the glue. We clamp, then we sand away the small impressions left by the clamps.
When finally all that is thought of has been done, has been cut and glued and fit and just right, then we sand all the surfaces smooth and perfect so the finish can be applied. Then we sand most of the finish back off as well. Sand, sand, sand. That's what we do most of the time.
I was working in San Diego in a boat yard when we finished with sailing about. A friend [John] came to visit. I showed him all around the boatyard where there were a couple of dozen people working, doing a couple of dozen different projects, from fiberglass repair, woodworking repair, metal fabrication, painting etc. John noticed almost everyone was sanding something. Sanding and sanding and sanding. That's what we do.
