This project was built and designed by Connor from Shopfix.

Connor shows a custom, fully adjustable miter saw fence designed to add accuracy, repeatability, and a clean built-in look to a permanent miter station.

Design

The fence pairs a slim plywood face with a rigid aluminum extrusion backing to achieve a built-in aesthetic while keeping the assembly light and strong.

Connor prioritized clean lines and alignment with the saw’s factory fence so the finished unit looks like part of the station and reads as a precision layout tool rather than an afterthought.

Construction and Hardware Choices

The build uses an aluminum profile with channels to accept slotted brackets and bolts, giving the assembly a secure yet adjustable backbone.

Plywood was mounted to the extrusion with recessed fasteners so the face sits flush, and prong-style T-nuts allow top-side tightening for quick adjustments without crawling under the work surface.

Adjustment and Alignment

Adjustability is the fence’s strongest feature: the plywood face can shift left and right for fine-tuning the measuring tape, and the entire extrusion assembly can slide front to back for aligning with the saw.

Connor achieves dead-on alignment by pressing a track saw guide up to the saw’s fence and sliding the plywood face until it contacts perfectly, then locking everything down for repeatable results.

Using the Fence in the Shop

With a calibrated measuring tape and a true-aligned face, the fence becomes a reliable stop system for trim, cabinet parts, and batch cutting, eliminating guesswork and repeated measuring.

Stops slide onto the top, cuts are repeatable, and the combination of rigidity and micro-adjustment makes this setup adaptable to other saw models or station layouts with minimal modification.

Overall Takeaways

This is a practical upgrade that focuses on trust: when the fence is aligned and the tape is dialed in, the shop runs faster and mistakes drop dramatically.

Connor’s approach—combining off-the-shelf aluminum extrusion with a shop-matched plywood face and accessible fasteners—offers a route to a professional-looking, highly functional miter station that can be tailored to different workflows.

Conclusion

The adjustable fence turns a miter station into a repeatable, confident cutting system, and its simple adjustments make it a high-value upgrade for anyone doing trim, cabinetry, or batch work.
