I have started building a coffee table and was not sure if I can omit the apron. It measures 48x20x19 all out of oak. The top is 2 10'' boards I joined together with Kreg jig and it is 5/4'' thick. There will be 4 legs that are 3 x 3 and a bottom shelf that will go in between the legs. The bottom shelf is 3/4'' and 46x12. I was going to use the kreg jig to screw in legs on 2 sides to the top. I was then going to run 3/4 2''x12'' board between the legs and screw that to the legs and top. I was then going to run a board down the middle and screw into top and the 2 boards (between the legs). So basically it will have aprons on the short sides of the table (but they will be small and hopefully not as noticeable) and then a long board up the middle. Will this be sturdy enough for a coffee table? The only reason I am doing it this way is I am running out of lumber. I do have some pine I could use as well. Has anyone mixed pine and oak? It is going to be stained a red mahogany.
