The Workbench


The first item a workshop needs is a proper workbench. I constructed mine in early 1999. The frame, lower tray and the drawers are Douglas fir while the top is red oak. I used a combination of designs to fit my space needs.

So the features of importance for this post thread are: it was custom made to just fit the width I had, I added draws and a shelf area not in most workbench plans to maximize my storage.

The top design is based on a one sold by PlansNow with the title "European-Style Workbench". The top size was custom for my area. The frame, drawers and tray were a combination of ideas from multiple plans I looked at sized to my available space.

The frame is made with a "knock down" approach. No glue is used. The drawer runners and lower tray shelf are screwed to the frame members. Thus they can be removed with a little effort. The frame itself is held together by bolts that fit into recesses in the beautiful Douglas fir. I've never taken it apart but some day one of my sons or grandsons will when they inherit it.

The top is made in two layers. The base is made from 2 layers of 3/4" birch plywood glued and screwed together. The top layer is 1" by 2" red oak strips that go the full length of the top. The oak strips are attached to the plywood base using a construction Adhesive called PL 200. This adhesive allows for expansion and contraction of the top to avoid warping. Finally a 1" by 3" oak trim is placed around the perimeter flush with the top of the oak. This trim is held in place by screws that only go into the plywood base. The top sits on the frame held by it's weight, about 100 lbs. Each frame leg has a steel pin sticking up that mates with a hole in the bottom plywood base so the top cannot shift. Two people are needed to lift the top off the frame.

The top is protected by coats of Behr brand Scandinavian Tung Oil (#600 natural clear). I usually add a coat once a year when I know I'll not be using the bench for a week or so.

After 11 years of use I recently refinished the top for the first time. Most of the effort was in removing perhaps 10 coats of Tung Oil and then doing a little sanding of the rad oak to get to a clean looking surface.
