I’ve long debated whether to add a permanent tool tray to my workbench: It would be handy at times, but it could also get in the way, or not be adaptable to my changing work requirements. So I added a tray that attaches to flush-mounted T-track using bolts, washers, and nuts, as shown. (Note that you will need to cut the T-track groove extra long so the bolts slide out easily.)

I plan to build other accessories that attach to the T-track, such as a small shelf for holding chisels upright but with the handles below the level of the benchtop. The possibilities are endless!
