Project Ideas
Business
Fitting-Free HVACR Brazing Service
Offer on-site swage-and-braze services for HVAC contractors and homeowners, replacing fittings with expanded connections to reduce leak points and labor time. Market the consistency (auto-rotating heads) and productivity (hundreds of swages per charge) as cost and schedule advantages.
Prefabricated Copper Line Sets & Stubs
Build a shop service that fabricates custom-length, swaged ACR soft copper assemblies for mini-splits and light commercial work. Deliver labeled, nitrogen-capped, brazing-ready ends sized 1/4 in. to 1-5/8 in., reducing field time and waste for installers.
Supply-House Pop-Up Swage Booth
Partner with local HVAC supply houses to run a pop-up swaging station. Contractors bring cut copper; you provide precise, even swages on the spot (including partial expansions where needed). Charge per swage, sell add-on brazing consumables, and book field jobs.
Copper Lighting & Home Decor Line
Launch an online shop (Etsy/Shopify) featuring swaged-joint copper pendant lights, sconces, towel bars, and candle holders. The tool’s repeatability lets you batch products with consistent geometry and clean, fittings-free seams that photograph well and command premium pricing.
Tool Rental + Micro-Training
Start a weekend rental service for the swage kit with all common heads, battery, and charger, paired with a short paid training session on safe swaging and brazing techniques. Target small shops and DIYers who need occasional access without full purchase cost.
Creative
Copper Bell Candle Holders
Create a series of tabletop candle holders by expanding short lengths of 1/2 in. and 3/4 in. soft copper into bell-shaped cups using the auto-rotating heads for smooth, even flares. Braze the cups onto straight stems and bases for a clean, fittings-free look. Patina or polish for contrasting sets.
Swaged Pendant Lights
Build minimalist pendant lights and sconces by expanding tube ends to slip-fit over sockets, stems, and mounting plates. Use the 2-stage collar on 3/8 in. and compatible heads for partial flares that register perfectly before brazing, producing repeatable, professional fixtures for a matching room set.
Modular Plant Trellis
Make a modular indoor/outdoor trellis where expanded tube ends sleeve onto straight runs, creating strong friction-fit nodes you can braze or leave press-fit. Design interchangeable panels (1/2 in.–3/4 in.) that assemble without bulky fittings, then add patina for a living wall effect.
Copper Wind Chimes & Garden Mobiles
Form tuned chime elements by expanding ends into gentle bells for richer tones, then braze simple loops and hangers directly to the tube. Combine 3/8 in. to 7/8 in. sizes for visual rhythm, and use swaged sleeves as hidden couplers to keep the design clean and weather-resistant.
Wall-Mounted Towel/Coat Rack
Craft a sleek rack with swaged crossbars that expand into posts for invisible joints. The even, consistent swages keep everything aligned while you braze, producing a sturdy, minimalist piece that can be finished in polished copper, lacquered, or aged verdigris.
