Hi,

I plan on building built in bookcases for my new home. I plan on using a
veneer type plywood available in 4' by 8' sheets. The bookshelves will be
72" in height.

What is the preferred method to make the long cuts? I was thinking a skill
saw for the rough cut then finding an 8 foot straight edge and cleaning the
edge up with a router.

Anyone have an idea on who makes a ONE PIECE 8 foot straight edge?

Thanks,
