This project was built and designed by Izzy Swan.
Izzy set out to make a compact, portable pocket-hole machine that could either travel to a workpiece or be mounted to a bench, with a single smooth motion to cut holes quickly.
The concept prioritizes speed and simplicity over a complicated clamping routine, serving as a proof of concept for a more refined, adjustable version to follow.

Design
The jig was designed around a single drill axis set at a fixed angle and a sliding assembly that carries the drill straight into the workpiece.
Izzy favored a lightweight footprint so the device could be moved to large panels instead of bringing panels to a stationary machine.
Rather than elaborate fences and stops, the layout relies on a simple guide rail and captured drill slide to produce repeatable pocket holes with one motion. This approach keeps setup time low and makes the jig useful for both on-site and bench-mounted work.
Lumber and Prep
The prototype was built mostly from plywood, milled and stacked to create the base, guide rails, and a wooden bush that acts as the drill guide.
Quick adhesives were used to hold parts during assembly so the build moved fast and allowed for iterative shaping and fitting.
Careful trimming and filling dials in the fit of the sliding components, and small trim tools are handy for cleaning up exposed edges for a tight, consistent slide. The result is a captured slide that stays aligned while under load.
Drill Mounting and Actuation
Instead of a built-in motor, the jig accepts a hand drill that rides in a wooden sleeve and is clamped in place for use. A simple hose-clamp style fastening secures the tool to the slide and keeps it stable during the drilling stroke.
Actuation is handled by a linkage and a single handle that pulls the drill forward into the workpiece and retracts it, so one motion produces a pocket hole. A traction pad on the actuator helps the user keep a steady grip while cutting holes.
Troubleshooting and Fit
Because the guide in the prototype is wood rather than a hardened bearing, there is a small amount of play during drilling, which Izzy acknowledges as a limitation of this first version.
Small adjustments—like tightening the slide fit and trimming filler material—improve repeatability and reduce wobble.
The build process highlighted useful shop tricks for finishing edge and fit, including trimming and flush cutting to make seams invisible and ensure the drill slide is captured cleanly. Those little refinements make the jig feel more robust even in prototype form.
Performance and Next Steps
The prototype performs well as a proof of concept and demonstrates that a portable, single-motion pocket-hole jig is practical and fast for many panel and rail applications.
The tradeoff is that a finished product will need a more precise guide and a built-in trigger or power solution for safer, smoother operation.
Izzy plans to refine the design into an adjustable, more user-friendly version and to share plans so others can build or adapt the concept. The next iteration will address the play in the guide and add conveniences like an integrated trigger mechanism.
Why This Jig Matters
Reducing setup time and moving the jig to the workpiece instead of the other way around changes how pocket holes can be used on large panels and assemblies.
A lightweight, repeatable device helps speed production and makes pocket-hole joinery more accessible for shop and on-site work.
The approach also encourages iterative design: test a simple idea, learn where precision is needed, and then refine the mechanism for the next version.
That cycle is a practical roadmap for anyone rethinking specialty jigs in the shop.
