Hello,

I am building a workbench for making furniture. I am getting close to finishing the base, but now, I’m having second thoughts about my design. I need to make a decision about this before I glue things up.

I decided to make a heavy bench of red oak. End trestles are ca. 3” square stock with through-mortise and tenon joints. I plan to draw-bore and glue these joints, so I expect that’ll be fine. I have a heavy top of laminated ash that’ll be over 2” thick when done. I have a set of stretchers between the trestles at the bottom ca. 2” x 6”.

I am wondering if this will be enough bracing—whether I ought to add two more stretchers at the top? I thought the workbench top, bolted into the trestles, would be adequate to stabilize the whole, would serve as stretchers, but now I am wondering if I bolt that top on solidly enough to serve that purpose, that expansion and contraction of the top may cause problems.

I believe I have seen designs that use a heavy laminated top and dispense with an upper set of stretchers.

What say you?

George

I took the second set of stretchers path. For two more stretchers you add a huge amount of strength. A 2” thick top is not that thick if the bench is long.

You get 3 inch long oak tenons going through 3×3 beams, you are not going to really need to drawbore and glue. It’s not going anywhere. In fact, if I were getting fancy, I would do some tusk tenons and make it where it could possibly be disassembled.
