Hi! I'm new at this, and am building two DJ roadcases from 15mm MDF. I've had the MDF cut to size, and I'm ready to start putting it together. I'm looking for advise from you pros out there! It needs to be strong for road use. Right now, my plan is to screw and glue L and T joints with MDF screws and wood glue. Some of the MDF screws claim to not need a pilot hole and are self-countersinking, but I thought it better to drill pilot holes the same diameter as the shank of the screws, squirt glue in before screwing them together, and countersink the MDF before putting the screwsin. Someone also mentioned using plastic blocks on the inside of the joints for mroe reinforcement. Thanks in advance for any help!
