I like your table and plan to pattern my new one off of yours. The legs on my current table are 2 x 4, and with the weight of the egg and construction of the table, the legs are now starting to push out so I want to use 4 x 4's. Since the Kreg system only goes up to 2" material how did you attach the apron to the 4 x 4's? Glue only? Would you make any changes/recommendations regarding this now that you've had a few seasons of use?
