Project Ideas
Business
On-Site Thread Creation and Repair Service
Offer a mobile service to contractors and facilities to create or chase 1/2-13 threads in equipment frames, mounting plates, and fixtures—especially in blind holes. Bundle the tap with the correct 27/64 in drill, cutting fluid, and depth stops. Bill per hole or per visit and upsell maintenance contracts.
Small-Batch Fixturing Plates
Manufacture and sell steel or aluminum plates with a precise grid of 1/2-13 blind-tapped holes for makers, welders, and small shops. Market them as modular clamping tables, welding jigs, or drill-press fixtures. Emphasize clean, accurate threads thanks to rolled-thread tap geometry and quality control.
Leveling Foot Retrofit Kits
Sell kits that include a 27/64 in drill bit, the 1/2-13 plug tap, cutting fluid, depth collar, and four leveling feet. Target woodworking shops, home garages, and small factories needing to stabilize benches and machines. Provide a simple installation guide and offer add-on services for bulk retrofits.
Maker Classes and Tool Bundles
Run workshops on drilling and tapping blind holes safely and accurately. Include hands-on projects (fixturing plate or clamp block) and sell take-home bundles with the plug tap, matching drill, fluid, and a tap handle. Partner with community makerspaces and vocational schools for recurring sessions.
Custom Mounting Plates for Tradeshow/Exhibit Builders
Produce pre-tapped 1/2-13 mounting plates and blocks for quick assembly of displays, signage, and rigs. The blind holes prevent hardware from protruding and damaging surfaces. Offer fast turnaround with standard patterns and charge premium rates for rush jobs and custom layouts.

Modular Workbench Fixturing Plate
Lay out a grid of 1/2-13 blind holes in a steel, aluminum, phenolic, or hardwood plate to create a universal fixturing surface for clamping, stops, and jigs. Pre-drill 27/64 in holes and use the plug tap to cut clean threads that don’t need to reach the bottom. The four-flute design helps clear chips in deeper holes, and the rolled-thread accuracy ensures snug-fitting studs and bolts.
Adjustable Leveling Feet in Furniture
Tap 1/2-13 blind holes in the bottom of heavy furniture or machine stands to accept readily available leveling feet. Drill 27/64 in pilot holes into the hardwood or metal legs and use the plug tap for durable threads that won’t break through the surface. This gives shop cabinets, benches, and tool stands a professional, adjustable base.
Custom Clamps and Toe-Clamps
Make your own aluminum or steel clamp blocks by tapping 1/2-13 blind holes to accept bolts and studs. Combine with slots and counterbores to build low-profile toe-clamps for milling, drill-press, or router-table setups. The tap’s heat-treated carbon steel construction and four flutes help maintain speed and chip control in repeated use.
Threaded Resin or Wood Knobs
Cast resin or turn wooden knobs with 27/64 in bores and tap them 1/2-13 to create robust, removable handles for jigs, presses, and fixtures. The accurate rolled threads provide a clean fit on standard 1/2-13 hardware, making the knobs interchangeable and easy to replace.
Heavy-Duty Wall-Mount Tool Hangers
Fabricate a steel backer plate with 1/2-13 blind-tapped holes to accept bolts and custom hooks for bikes, ladders, and heavy tools. The plug tap is ideal for blind holes so you don’t break through the plate, and the laser-etched size marking helps keep your tap system organized.
