Outdoor Sectional – Part III

Outdoor Sectional – Part III
All that is left is the seat and back slats.

What does every good outdoor sectional need? A good backrest. So after finishing the base, I got started on building the backrest. 

Since I am not a robot, the key to the backrest build was to make sure it had a slight angle to it for comfort. I once again set up a stop block for consistent lengths on all of the backrest supports and cut all of the pieces with a 6° angle. The angle is on both sides of the backrest support, so that it connects to the base square and the top runner sits square as well. It was worth it to really take my time on this step, as the angles had to be oriented correctly relative to each other.

Almost forgot! Before cutting the backrest supports, I ripped the 2×4 down to 2½”. That way, there is room for support slats on the face of the supports without extending past the top runner.

Now it was time for assembly. I started with the bottom 2×2½  runner and marked out the spacing for each backrest. Then, I used outdoor glue and a couple wood screws to secure each support in place.

Backrest in assembly.

Following the same procedure, I marked and attached the top 2×4 runner. The runner has a 45° miter on it for where the long side meets the short side. It was a pretty quick process to build up both the long and short backrests.

I had previously moved the entire sectional base out to the front porch, so I brought the backs out as well and attached them to the base. Again, I used outdoor glue (lots of it) and wood screws to attach them.

I used clamps to hold the back in place while screwing it in.
Looking good. Notice the old cabinet shelf used as a temporary seat.

It is really starting to look like a completed outdoor sectional! I need to attach the seat and backrest slats and then stain it and that’s it. So close I can almost taste it, or feel my butt in it in this case.
