Hey, Merry Christmas. Nice work bench. Mine are nearly the same, down both walls of the shop. If you decide to mount the vice, mount it close to the leg and double the plywood under it. Then use long 1/2" bolts all the way through with thick washers. (This is what I did to mine after a serious hammer beating session nearly broke it off the bench. Thennnn, after reinforcing the bench mount, I broke the vise in half. LOL, Harbor Freight wouldn't warranty it. I bought a beefier vise and haven't broken it YET.
