Backrest and Seat

In my last post the parts and pieces were completed for the seat frame and the backrest. Since that time the slats were finished (Osmo 3043 using Mirlon abrasive pads). The top and bottom rails were finished as well but their tenons were taped off. The final step was to form the sides of the backrest with spokeshaves then glue the entire piece together and finish it completely. Before assembling that though the through mortise and tenons for the arm rests had to be fitted.

The process for making the seat assembly was similar. It consists of two end pieces which are supported by the stretchers between the two legs. The front rail is attached with a haunched mortise and tenon joint and the back and center support use mortise and tenons as well. To accommodate the webbing from House2Home, a 1/8 slot is routed for the clips. Kind of tricky, it’s best to remove about 1/8 of material so the webbing lays flat. This was done on the tablesaw with a rip blade which requires dropping the wood onto the blade and then lifting it off — care required on this operation. The recess is then squared off before I assembled and finished the entire seat.

Armrest to Leg Assembly

While designing this piece I looked at so many Danish Modern pieces on Pinterest it made my head spin! I wanted something graceful and not just a machined, routed piece. I had set aside a piece that had some interesting grain for the armrests so that determined how wide they could be. Even though they’re about 4′ apart it’s important to me that the grain matches. The bottom has a simple, long chamfer while the top has a slight radius. Sculpting began with my old Stanley 151 and finished up with a Bogg’s style Lie-Nielsen . The antique Stanley removes material quickly without clogging while the L-N does a beautiful job of finishing. After drawing in the “limit” lines of the bottom chamfer work began with the spokeshave, shaving to the lines. Once the cut was close a sliding bevel was set to make the chamfer uniform on the edges and the ends formed to match.

The armrests are attached with wedged, through mortise and tenon joints. The method that Mike Pekovich from Fine Woodworking Magazine uses is what I prefer too. Here’s a LINK to it but you may need to be a Fine Woodworking member. He utilizes a spacer to get the width just right, this way you only need to set your marking gauge one time. Only variation I did was to use a 3/8″ drill on the drill press to remove the bulk of the material. He uses a smaller bit and makes more holes; either way works. I could do this because my tenon is 7/16″ wide. I also used this method on the Japanese toolboxes for laying out both the mortise and the tenon. I’ve been presenting my work in a slide show format to simplify the blog — let me know if I succeeded!

At this point this project is almost ready for final assembly. The last thing that needs to be done is to apply the Osmo to the leg and armrest assemblies. We get our foam at Galaxy Foam and Upholstery Supply here in Las Vegas. They have foams of all densities and wrap batting around it which makes for a better cushion. Also bought the material there and unfortunately it’s too thick for Diane’s machine so they are currently being sewn at Oscars Upholstery. I’ll do a final blog on this when the cushions are done and the love seat is ready. I’ve been told my blogs can get long winded but appreciate any comments or questions you may have, thanks — John
