I will be making two benches to go with a dining table, one bench will be about 78" long, the other one will be about 66" long.
I'm thinking of making them 18" deep. They will be along one side and one end of the dining table, and each one will be against a wall.
Should I use 8/4 white oak for these, or will 6/4 be thick enough - ending up at ~ 1 1/4" final thickness.
I plan on supporting the 66" bench in two places - can I do the same with the 78" bench? Or will I need to support it in three places? Figure that at times there will be 3 to 4 adults on the 78" bench.
The home owner is undecided on whether or not she'll use any cushions at the seater's back. I have a feeling she will not. Is 18" a good depth?
Thanks for any opinions you can offer, Mark.
