Storing Small Parts: Our Mobile Tool Cart from the Carpentry Shop

Are you still looking, or have you started setting things up yet? As we move into our new woodshop , we faced a decision: Should we go with the classic wooden shelving unit with its countless, compartmentalized drawers?

Why We Made Our Small Parts Warehouse Mobile

Everyone is familiar with the system, and everyone knows the problem: You search, you rummage, and in the end, the one M6 screw you need for the assembly is missing. That costs time and patience.

We wanted a solution that combines transparency with mobility. The goal: The parts shouldn't be gathering dust on the wall, but should be where they're needed.

Transparency Beats Searching

Instead of solid fronts, we opted for transparent tilting bins . The advantage for operations is obvious: You can see what’s inside as you walk by—and, most importantly, when stock is running low. A simple label also helps ensure you don’t miss the right time to reorder.

Order That Adapts

The centerpiece of our cart is the reversible center panel made of black MDF. While the folding drawers are securely screwed in place, the tool holders remain adjustable thanks to cross-milled keyways. Using simple plastic “ slot nuts ,” pins for saw blades and cutters can be positioned in a matter of seconds. The “ slots ” can also hold tool trays or iPad and tablet holders . This way, the small-parts storage unit can be transformed into a fully-fledged machine setup cart as needed. This multifunctionality saves us valuable floor space in the workshop.

A practical tip

We mill the slots using the a multi-tooth cutter on the front and back in a staggered pattern. This preserves the material thickness of the center wall and ensures the necessary rigidity, even when the cart is fully loaded.

What We Would Do Differently Today

At first, we had to laboriously slide the slot nuts in from the side. That’s incredibly annoying in everyday workshop life. So we used a groove cutter to slightly widen the outer edges of the slots . Thanks to this “keyhole principle,” you can insert brackets exactly where they’re needed at any time—without first having to move other parts out of the way or take the car halfway apart.

Mobility Requires Carrying Capacity

Never underestimate the combined loads here. When many small parts, a few fixtures, and heavy milling cutters are concentrated in a tight space, those cheap hardware-store casters will quickly give out. That’s why we use four heavy-duty castors casters, so the cart remains easy to maneuver precisely and stays stable even when fully loaded.

Three Questions for Your Organization System

  • Stationary or mobile? Does it make economic sense for the employee to go to the materials, or should the materials be brought to the workstation? While mobile solutions offer flexibility, they also require space, clear responsibilities, and discipline.
  • Visual inspection or ERP? Do you need a direct view of your inventory, or are your processes already so digitized that small parts are managed entirely through the system?
  • Choosing materials: Does it have to be sheet metal, or do you still have some material left over on the scrap shelf that could be used to build a sturdy frame out of multiplex or MDF? For our carts, we still had some base frames left over from a prototype series of our shelf carts. A wooden frame would be just as feasible, though, and is often quicker to build yourself.

Our solution isn't a one-size-fits-all approach; it's based on our own practical experience. Perhaps a T-slot , or a base unit made entirely of solid wood, would be a better fit for you. Ultimately, the only thing that matters is that the system fits your business and the workflow in your department.
