Master Custom Bevels with Kevin Tappin: Half-Day Stained Glass Workshop in Denver

Kevin Tappin’s Customized Bevels workshop turns a common studio bottleneck into a hands-on victory. Held at the D&L classroom at 1440 W 52nd Ave, Denver, CO 80221, this half-day stained-glass class (9am–1pm) teaches you to cut, grind, and polish custom straight-line bevels that don’t exist off the shelf. With a maximum of eight students, the session emphasizes small, precise coldworking using lap wheels and a progression of diamond grits to reshape stock bevels into perfect fit pieces for your panels. The class highlights are plain and practical: real bevel manipulation, step-by-step use of grinding tools, and finishing techniques that yield a polished edge ready for leading or copper foiling. Kevin Tappin — owner of Stained Glass Stuff in Ottawa, Canada — brings two decades of coldworking experience, a patient teaching style, and a focus on repeatable methods that speed complex designs toward completion. All glass and supplies are provided, and the D&L classroom is stroller- and wheelchair-accessible, making the workshop approachable for many skill levels. Expect an introductory demo, individual work time at lap wheels, and one-on-one adjustment coaching. Safety is central: eye protection, careful handling of diamond pads, and dust control protocols keep the bench clean. Students under 15 must be accompanied by a participating guardian. Practicalities are tidy — arrive ten minutes early, park on the west side of the building, and use the classroom door beside the chain-link fence; an on-site bathroom is available. Why this class matters in Denver’s maker scene: it solves a specific technical gap that stalls stained-glass projects worldwide. Instead of improvising awkward filler pieces, you’ll leave with the ability to produce straight-line bevels that lock into complex patterns, increasing the creative options for windows, panels, and fused works. The workshop also offers a rare chance to learn coldworking tips from an international studio owner whose techniques grew from early 2000s fused-glass practice into a focused, 20-year trade. Practical takeaways include tool selection, grit sequencing, polishing technique, and design considerations for integrating bevels into leaded or foil constructions. Whether you’re a hobbyist troubleshooting a stalled panel or an emerging artist wanting cleaner finishes, this class gives concrete skills and confidence. Winter-weather continuity means classes usually run as scheduled; contact the host for rare cancellation notices. Walk away with small custom bevels you made yourself and a clearer process for finishing future projects. The small class size means plenty of bench time and personalized feedback; expect to complete multiple practice bevels and at least one project-ready piece. Materials cover common glass types used in bevel work, and Kevin will explain when to choose grind-over-replace strategies. Ideal for makers looking to level up technical finish work, this workshop is an investment in cleaner stained-glass outcomes.
