Project Ideas

Business

Mobile Deburr & Edge-Break Service

Offer on-site edge-breaking and deburring for laser/plasma/waterjet shops. The QDC system enables rapid grit changes and high throughput on ferrous parts, with a die grinder rated up to 30,000 RPM. Price per part or per linear foot of edge.


Weld Cleanup and Blend-Out

Provide fast post-weld cleanup—spatter removal, weld bead blending, and surface prep for powder coat or paint. Use 24-grit discs for removal, then step through finer grits to blend. Market to small fab shops and deliver same-day finishes.


Custom Texture Panels for Interiors

Produce textured steel panels for designers and builders: swirls, crosshatch, or directional grain patterns. Build a sample deck with multiple grit progressions and finishes. Sell panels as wall features, backsplashes, or signage backers.


Tool Refurbish & Resale

Acquire rusty wrenches, vises, and clamps; clean, deburr, and apply a uniform brushed finish using the quick-change discs. List restored tools on marketplaces with before/after photos. Upsell with protective coatings and custom engraving.


Hands-On Surface Prep Workshops

Host short courses teaching safe, efficient metal surface prep with QDC discs. Include demos on deburring, blending, and finish patterns; sell take-home kits (mandrel, assorted grits, PPE). Partner with maker spaces and fabrication schools.

Creative

Brushed Steel Wall Art Tiles

Create a mosaic of small steel tiles with unique textures. Use 1 in, 24-grit QDC discs to remove mill scale and establish bold crosshatch or swirl patterns, then switch to finer grits for a satin sheen. Arrange tiles in geometric patterns and clear-coat to preserve the finish.


Upcycled Cutlery Wind Chimes

Transform old steel cutlery into polished, deburred chimes. The 1 in Quick-Change discs let you quickly clean, edge-break, and apply decorative swirl finishes on tight curves. Finish with a light oil or clear coat for outdoor durability.


Knife Spine Rounding & Satin Finish

Refresh budget knives or shop-made blades by rounding sharp spines and choils using 24-grit discs, then blend to a smooth satin with finer grits. The small diameter discs reach tight radii, and quick changes keep heat low and control high.


Raw-Steel Motorcycle Tank Aesthetic

Strip to bare steel and apply a uniform linear grain for a custom raw-metal look. Start with 24-grit for weld cleanup and scale removal, then blend upward in grits for a consistent directionality. Seal with a clear fuel-resistant coating.


Industrial Metal Coasters

Use laser-cut mild steel blanks, deburr edges with 24-grit, and add a radial brushed pattern using a simple turntable jig. Stamp or etch a logo, then finish with oil, wax, or clear. The 1 in discs are ideal for precise edge-breaking and consistent textures.
