I’m making a Walnut counter top for my kitchen island. The 8/4 boards will be edge glued and with biscuits (to help with alignment).

I will have a 12” overhang for stools to sit under. I don’t like the look of corbels. So here’s my idea to support the overhang:

I am going to rout out a 1” groove across the underside of the counter top, perpendicular to the length of the top, and add 1” square steel bar stock across the glue up to act as struts for support. These would be screwed into the top from underneath.


Do you think this will work for a) support and b) wood movement?

And, how far apart would you recommend I put these support struts?

I’d hate to waste $850 in walnut. BTW, the counter top is 11’ long.

Thank you in advance
