What happens in this clip

Based on your detailed design plan, proceed to cut all the necessary lumber pieces. This includes vertical posts, horizontal cross-members, shelf runners (the supports that the storage bins will slide on), and diagonal braces for structural rigidity. Also, cut the plywood panels that will serve as the workbench top and any solid shelves. Use appropriate power saws for clean, precise cuts. After cutting, it's advisable to label each piece according to your plan to facilitate correct assembly.

Goal: Prepare all wooden components for assembly

About the full video

This project outlines the construction of a custom modular storage and workbench system designed for a garage or workshop. It features wooden frames built to accommodate plastic storage bins, a dedicated workbench section under a window, and casters for easy rearrangement. The system prioritizes organization, accessibility, and efficient use of space, allowing for flexible configuration to suit various needs.

Step 3 of 10: Create a Cut List

Translate your design into a detailed cut list. For each piece of wood (e.g., sides, shelves, back supports), list its exact dimensions (length, width, thickness). This will help you purchase the correct amount of material and minimize waste.

Questions about Under-Stair Shelving

What are the essential tools I need for accurate measurements in an angled under-stair space?

Beyond a standard measuring tape and pencil, an angle finder or a protractor is crucial for accurately capturing the slope of the stairs. Also, a long straight edge or level will help you mark level lines and check for plumb, ensuring your shelves are straight and true despite the angled surroundings.

Beyond basic hand tools, what power tools would make this under-stair shelving project easier for a beginner?

A miter saw or circular saw with a guide will significantly improve the accuracy and speed of cutting your lumber, especially for repetitive cuts and angles. An electric orbital sander is also highly recommended to efficiently prepare all pieces for finishing, saving you hours compared to hand sanding.

What are the most important safety precautions I should take when cutting and assembling lumber for this project?

Always wear safety glasses to protect your eyes from sawdust and flying debris. Use hearing protection when operating power tools and ensure your work area is clean and well-lit to prevent accidents. Make sure all lumber is securely clamped or supported before cutting to avoid kickback.

The project is listed as 'beginner' and '3 days'. Is this estimated time realistic for someone completely new to woodworking?

While classified as beginner, the 3-day estimate often assumes some prior familiarity with tools and a focused work schedule. If you're completely new, allow for extra time, especially for careful measuring, precise cutting, and thorough finishing, as these steps are critical for a professional-looking result. Don't rush the process.

What's a common mistake beginners make when measuring for under-stair shelving, and how can I avoid it?

A frequent mistake is not fully accounting for irregularities in the wall or floor, or failing to precisely capture the stair's varying angles, leading to shelves that don't fit snugly. To avoid this, create a detailed template using cardboard or scrap material for complex angles, and always 'measure twice, cut once' to confirm dimensions.

Are there alternative materials to dimensional lumber that might be easier for a beginner or offer a different look for under-stair shelving?

Plywood or MDF (medium-density fiberboard) can be good alternatives, often providing flatter surfaces and being easier to cut into large panels for shelves and backs. These materials typically require edge banding or painting for a finished appearance, which might add a different aesthetic and complexity to the finishing steps. Consider pre-made shelving kits for the simplest approach, though customization will be limited.
