Workbench Cabinet

Marc Spagnuolo

Most workbenches feature a base that leaves a lot of open and unused space under the bench. My Split-Top Roubo has a shelf on the bottom that pretty much only serves as a place to collect junk. A much better solution is a custom-designed cabinet that gives me a place to store tools without getting in the way of bench's functional parts. While this unit is designed to fit the Split-Top Roubo, it isn't difficult to resize for any other workbench. This project is for the cabinet only. The Split-Top Roubo Workbench is a separate build available here.

Dimensions are 41 1/2" W x 22" D x 16" H

    The assembly can be daunting, but we’ll take it one step at a time.

    The drawers are assembled, fit, and then slides are attached.

  9. Door Construction

    Let’s make a mitered frame and panel door.

  10. Door Inlay & Keys

    Keys are added for strength and inlays are added for looks.

I was excited to learn about the inlay line style in this project and was not disappointed. As a teacher myself, I’m impressed by Mark’s presentation as it’s always fun and clear. I’m going to watch all of these eventually.

Please do not be apprehensive on this project because it’s labeled “under work bench cabinet”. It’s instructions relate to a wide variety of cabinet making and skills, which can be utilized for many applications. Marc is clear, concise and thorough, a good project instruction for a multitude of projects.
