I am building a workbench and am hoping to get some advice on attaching its top. The workbench supports are red oak ca. 3.5” square. The top is laminated ash 2 5/8 thick, finger-jointed boards. I am thinking, on what will be a very heavy bench, to use four sturdy bolts, 3/8” – 1/2” diam. recessed into the top. I could use square ended bolts in a chiseled out square recess or hex head bolts and washers recessed in a forstner-bored hole. Any thoughts on what kind of bolts to use?
Another concern is allowing for wood movement. Since both the top and oak members are laminated I’m hoping wood movement won’t be too much, but if I bore the bolt holes larger than the bolts to allow for some movement, how much larger should they be?
