In the workshop, tool organization is a must. A good toolbox upgrade or tool storage box idea can make a huge difference in your tool organization. In this video, I’m making some replacement dividers for my machinist parallel storage box. The dividers that came with the box were made of foam and didn’t work very well. Granted, this isn’t an expensive set of parallels, but for what I’ll be doing, they’ll work just fine. I used my milling machine and some scrap plastic to upgrade the dividers.
