Project Ideas

Business

Mobile Weld Prep & Finishing

Offer on-site beveling, weld cleanup, spatter removal, and blending for gates, handrails, trailers, and small fab shops. The 9,000 rpm motor and vibration-reducing handle enable fast, consistent results. Bill hourly plus consumables and travel.


Epoxy Floor Edge Grinding Partner

Specialize in edge work for epoxy/urethane floor installers where large grinders can’t reach. Use diamond cups with a dust shroud and HEPA vac to prep along walls, posts, and steps. Charge per linear foot or per room, targeting contractors and garages.


Tile & Thinset Removal Service

Provide fast tile cuts, thinset/mortar removal, and adhesive grinding during remodels. Swap between diamond blades and turbo cups to clear substrates for new installs. Offer day-rate packages that include dust control and debris management.


Headstone and Monument Restoration

Clean lichen, oxidation, and mineral deposits from granite and marble using appropriate diamond polishing pads and gentle wire/nylon wheels. Re-edge and reveal lettering, then seal. Market to cemeteries, memorial services, and families; price per monument.


Custom Metal Signs & Brackets

Produce house numbers, ranch/farm signs, and decorative shelving brackets from flat bar and sheet. Cut profiles with cutoff wheels, deburr and bevel with flap discs, apply patina and clear coat. Sell via Etsy, local markets, and contractor partnerships with installation upsells.

Creative

Forged-Look Metal Garden Sculptures

Use scrap steel, bolts, and rebar to fabricate abstract or botanical forms. Cut stock with cutoff wheels, bevel and blend with grinding discs, then add scalloped textures and highlights using flap discs. The low-profile gear case helps reach tight internal angles for clean transitions.


Concrete + Steel Side Tables

Weld a simple steel base and cast a concrete top in a plywood mold. After curing, use a diamond cup wheel to flatten and polish the surface, chamfer edges, and clean up welds on the base. Quick wheel changes let you switch between metal grinding and concrete finishing swiftly.


Railroad-Spike or Rebar Knives

Rough shape decorative knives from spikes or rebar. Establish bevels with a grinding disc, refine with flap discs to a satin finish, and add filework or decorative jimping. Wrap handles with paracord or attach scales for a rugged, display-worthy piece.


Shou Sugi Ban Textured Wall Art

Lightly char softwood boards with a torch, then brush with a wire cup to raise the grain and reveal dramatic texture. Blend edges and create soft contours with flap discs, then oil or clear-coat for a striking dimensional panel.


Stone Lanterns and Stepping Stones

Shape pavers or soft stone (soapstone, limestone) with diamond blades and cups. Round over edges, carve channels for lighting, and inlay metal details. The adjustable guard and side handle aid control for smooth, consistent profiles.
