Since it is summer time, I wanted a bench to be able to work outside. I have lurked around this site and others for years drooling over other people’s workbenches, but never built a decent one myself. I had read the Schwarz book several times and decided that I would try the Roubo bench in Douglas Fir.
Of course, the local big boxes didn’t have great stuff, but I did find 2 decent 4”x8”x12 footers. Of course I had to knock those down to 6 foot myself in the parking lot. Sorry I don’t have that picture. I let those dry outside for several months and looked around for decent 4×4 legs. Luckily, Ganahl Lumber in Pasadena had kiln dried doug fir 4×4. Expensive but much better quality than HD. And they are straight and strong.
I had heard from several bloggers that Doug Fir is not easy to chop out mortises. I drilled out as much as I could. I wasn’t the greatest at staying plumb and true. My chisel work needs improvement and it took two weekends to finish 4 mortises, but they were done. Thinking back now, I could have used my oscillating multi tool to help square up the walls. I will have to try that if I get enough time to build a matching bench seat. The mortises are inch and half by three and half all the way through the top. They are set back two inches from the edge. The tenons were a joy to cut by hand. I cheated at the start with the Veritas saw guide. Glue up was not easy by myself, but the top’s weight helped a lot. I wedged the tenons and then cut them flush.
Since this bench will live outdoors all year, I researched a lot about finishes. I normally like tung oil for outdoor, but I read the FWW article that mentioned clear penetrating epoxy sealer. I didn’t want a thick glossy bar top, and this stuff is great. I soaks right into the wood. I applied two coats and then finished with spar varnish. It’s a little glitzy for a workbench, but it should hopefully handle Southern California weather. I added extra epoxy to the bottom of the legs so I can hose off the patio and not worry about.
So far it is rock solid. The top adds plenty of weight and the through tenons keep the legs firmly in place. Not sure I will build another bench for a long time, but glad I did this one. It’s also doubles as our picnic table.
Have a great summer and thanks for reading.
