Took some pics today for you. Basically it is a melamine box under the saw with a slot at the top rear and a hole in the middle of the base of the box with a 5 inch blast gate silicone glued to it. The line connects to my main behind the kick board. You can see how I first installed the system on my YouTube channel. https://youtu.be/A0b8aUdMPWk
Thanks for the advice. I am still in the process of laminating the top. Doing it sets of 3 due to limited clamps and glue time (Arizona heat). Also in between glue ups I am rough flattening each set just to save some work on the back end. Not caring too much about the whole length being flat mostly just the width trying to level all 3 edges.
