I have aquired some good size pieces of black laboratory countertop from a job. I haven't decided what to do with it yet but am in need of a router table. I was thinking that this would make a perfectly flat top and would remain that way for years. The stuff is super hard though and do not know if it is worth my effort. Has anyone ever had to cut or rout this sort of material? Would it be worth making a recess for a router plate to gain easier access of zero clearance inserts as well as other accessories that easily mount to the plates, including the router itself? Seems as though it would be tough to machine this recess. I just like idea due to the durability of this stuff as well as the stability. It would never move from enviromental reasons and would never sag from router weight.
