I am thinking 64" edge is not that easy to get perfection straight for a table.
I found some nice real marble at Lowes at $9.95 a sq. might as well just go with that. Nice thing is that i can open all the boxes and pick the nicest ones, the bright white is nice near the window and remnant guys don't seem to have much marble anyways. The edge i will just smooth down a bit and leave it exposed, with the wood trim coming flush from bellow. I am thinking to use 1/4" pieces of wood for separators/grout?
ps, i am always careful with ear/eye protection and dust protection, my father lost his hearing i think because of years around the saws, and my sister because of music.
Will post some pic's when it is done.
