Hi Everyone, I'm newer to the woodworking world, but not green. I teach entry level woodshop to high school students so I do know how to use woodworking tools safely and make basic projects. I have designed a table I'd like to build, and I know it will really push my skills. I have two areas circled on the image shown and would love your input. The top will be slab black walnut, legs ash, and middle stringer/supports also walnut which hopefully is clear in the model I made. All material (with the exception of the top slab) is 8/4 rough, so the legs will be 2 boards approximately 5.5" wide laminated together, so final depth of the legs will be 3". For circle A - how would you make this joint? Originally I thought of a miter for the two portions stemming from the legs, and cutting a spear into the middle, but then I realized I don't know how I would clamp that. Any ideas? For circle B - would you recommend laminating so the seam is showing, and make two notches that will hold the middle support? I'm open to other options, I thought of drilling a forstner bit through, lag bolts, and walnut plugs. I appreciate your help in advance! Thank you!
