I am making a 6 foot long dining room table bench out of cherry and some hard maple. The bench will feature 10/4 legs and 6/4 stock for everything else. The bench is 18” high and 16” wide. My concern is whether I could support 500 lbs of weight on this bench without it failing. If not, then whats the best way to preserve the design but make fixes to it?

Here is a link to the google sketchup model.

And here are some pictures of the bench.

Any thoughts?

I would think so and would build it with confidence if it were me.

I have had good luck with my two rail bench, a design very much similar to yours.
My tops were 8/4 and finished at 1-1/2” thick. If you are worried about the seat boards sagging, just make the top rails a little wider. 6/4 thick x 3” wide rails should be quite stout.

Behold! The sagulator.

I made some guesses for you and it looked ok. You can put the numbers in yourself.

Excellent, any thoughts on whether I can glue the top right to the aprons and legs, or should I be worried about wood movement?

Always think about wood movement. I’d be careful about gluing that top to that base, there is a lot of movement in that top… Also be careful how much expansion there will be in those ends between those 2 posts. I’d probably do some hefty tabs screwed to top that slot into the base, much like a table top. That would allow for movement but still secure the top down nicely.

Good luck, post some pics!
