I used standard drawer guides for the lower drawers because they weren't very deep. But for the 48" deep drawers, I decided against using expensive drawer guides and instead I made the the old-fashioned way with a twist: I used HDMP (high density molecular plastic), which is super slippery stuff. In this video I also demonstrate how to use a router and template to mount the drawer pull/latches.
