Here is my workbench designed around a 11’ 12/4 piece of ash that is 10” wide. I wanted something with a very solid work area and large assembly area. Bench is 8’ long and 4’ wide. Center section is 2 layers of mdf that can easily be flipped and switched to “renew” the top. Center section is housed in a frame of Doug fir, tool tray is from an alder project gone bad… End vise was garage sell find, Wilton “L” vise (don’t know the name) was free because the clips that work the lock broke one hose clamp later it works! Legs are laminated fir, and a touch of mahogany for the L vise block… Sealed with a few coats of general water based poly. I am very happy with this bench, it is big and sturdy! My workshop is very humble but works well! Just an old pvc billboard for a roof works well when you live in the desert!
