When it comes to fine woodworking, precision makes all the difference. Whether you're cutting tight joinery or making repeatable crosscuts, having the right jigs transforms your table saw from a simple cutting tool into a true joinery workhorse. In this article, we’re showcasing two essential DIY upgrades: an Adjustable Tenoning Jig and a Precision Crosscut Sled—both designed to deliver professional-quality results without expensive commercial gear.
Adjustable Tenoning Jig
If you regularly cut mortise and tenon joints, this adjustable tenoning jig is a game-changer. It delivers clean, accurate tenons with smooth cheeks that are ready for glue-up straight from the saw—eliminating the extra sanding and tweaking that often comes with band saw or dado blade methods.
This jig rides securely in your table saw’s miter slot and holds your workpiece firmly upright, thanks to an integrated clamp and a sturdy vertical fence. What really sets it apart is the built-in micro-adjustment mechanism, which allows you to dial in your tenon thickness with incredible precision. Whether you're cutting a couple of joints or batching out a dozen, the repeatability is spot-on.
The design is simple to build using basic shop materials—no specialty hardware or complicated joinery required. Its three main components—a base, a vertical support, and a clamping assembly—come together in a way that’s both approachable for beginners and reliable enough for experienced woodworkers.
If you're looking for a weekend project that will raise the bar on your joinery game, this jig is worth every minute. It’s a durable, shop-made alternative to pricey store-bought models and delivers results you’ll be proud of.

Precision Table Saw Crosscut Sled
A well-built crosscut sled is the cornerstone of accurate woodworking—and this version checks all the boxes. Designed for precision, support, and versatility, this sled turns your table saw into a powerhouse for clean, accurate crosscuts.
Built from MDF and laminated for smooth, stable performance, the sled features a pivoting fence that makes it easy to dial in exact 90° cuts. A pair of stop blocks lets you set up repeatable cuts with confidence, while an integrated T-track system gives you room to customize with hold-downs or other accessories.
Unlike basic sleds or a standard miter gauge, this version offers full workpiece support—even for wide panels—and a zero-clearance base that helps prevent tear-out. It’s safe, efficient, and remarkably accurate, making it perfect for everything from furniture building to cabinetry.
Once you’ve used it, you’ll wonder how you ever managed without it. This is a sled you'll reach for on nearly every project, whether you're cutting parts to size or making exacting trim cuts for joinery.
