I have a small shop of 12' x 20' so every foot counts. When I do a project for the shop it has to be multipurpose. I added T-track to the top so it could also be used for assembly. I added a sliding tray under the bench for my mortising unit and pocket hole unit, the other side is for Festools. I added a sliding tray under the chop saw for storage of my CNC unit, only temporary. I also added dust collection enhancements for the miter saw. The unit was not too difficult to build but the tight space was a challange.
