I'm new to woodworking and am looking to construct a workbench. I see that 3"-5" of thickness is called for in many plans. I don't have access to a jointer or thickness planer but I can get a top made out of hardwood by a local manufacturer. However, they only go to a thickness of 1 3/4. So....should I a: by more than one top and laminate and if so what's the best way to handle that? b: should I just go with 1 3/4 and that will suffice? or c: should I source thicker lumber and hand plane and if I hand plane will I get a satisfactory result? Thanks in advance.
