I used screws to put the cut off spindles on as legs and cut braces for extra support.
We used a 1/2 inch block for a spacer, so that the water will drain off, because it is an outdoor bench after all. And of course, we gave it a coat of outdoor paint to help keep it sealed. {we recoat it every 2-3 years}
Once it was done we painted the top but left the spindles to weather with their original paint, and it has brought a beautiful patina over the years to our outdoor bench.
Here she is!! From putting beside a long dining table for family get togethers or just hanging out on the porch by the pool, we’ve found this outdoor bench to be one of the most useful furniture projects we’ve ever built.
