After receiving some very awesome feedback from a few people on this site I’ve gone forward with the project by screwing a 3/4” piece of ply to the stop and then putting a 1/8” piece of hardboard on top of that. I then went ahead and routed slots for the t-track which will hold the fence I’m working on. I’ve got a cutout for my router (not attached yet) and then I continued the 5/8” miter slots that are on my Craftsman TS. I also raised the saw blade through the hardboard and am using that as my zero clearance insert. I countersunk screws into the hardboard to attach it to the plywood so that if and when they get banged up I can just switch them out with new pieces. I also cut two large holes into the piece holding the tablesaw so that the sawdust collectl into the box below it which I can then simply vacuum out.
So here are the latest pictures. One question I do have is if I should apply a coat of poly or something to the top of the hardboard to make it a little tougher and more resistant to scratching and such.
