Rob from Let’s Make Things shared the woodworking tip featured in this video.
Rob demonstrates a simple, shop-built tall fence—called a Fence Sleeve—that slips over an existing table saw fence to give better support when cutting tall or narrow stock.

Design and purpose
The Fence Sleeve is designed to slip over a factory fence and create a taller, more supportive reference surface for long, thin, or tall pieces. This keeps material better supported and reduces the chance of tipping or kickback when making narrow cuts.
Materials and prep
The build uses common sheet goods and a wear-faced panel for the face, chosen for flatness and a smooth sliding surface.
Rob highlights that plywood often has a slight bow, and the sleeve can be oriented so those bows pull the assembly tight rather than push it out of square.
Assembly and attachment options
The sleeve is glued and clamped around the existing fence, with a dadoed pocket to seat a secondary shelf so everything registers flush at the top.
For fastening, a simple bolt-and-knob arrangement works if the saw’s track accepts a T-bolt, while a desktop clamp on the end can stop rearward movement if a T-bolt isn’t available.
Using the sleeve: accuracy and safety
With the sleeve in place the fence becomes a rigid, square reference for tall or narrow parts, which allows safer cuts that otherwise feel sketchy against a low fence.
Rob also emphasizes balancing the sleeve and using incremental fence clicks to keep the assembly straight before making precision cuts.
Miter gauge channel and support ribs
To expand capability, Rob cuts a miter-gauge channel into the sleeve’s face so the table saw miter gauge can run against the tall fence for things like lap joints and tenons.
He adds ribs under the face to keep the front surface stable where the channel is cut, creating a solid bearing for the miter gauge without weakening the sleeve.
Finishing and wear protection
Any exposed melamine edges are sealed to slow moisture movement and prevent swelling, and a slick, wear-resistant tape (UHMW) is recommended for the miter gauge track to improve glide and durability.
Small finishing touches and a snug fit matter most for longevity rather than fancy hardware.
Overall takeaways
The Fence Sleeve is a practical, reversible way to turn a standard fence into a tall, accurate reference without permanently modifying factory hardware. It’s adaptable, inexpensive, and focused on improving support and safety for joinery and narrow cuts.

Matt’s Take
These are my personal thoughts and tips based on my own experience in the shop. This section is not written, reviewed, or endorsed by the original creator of this project.
This type of auxiliary fence is one of those shop helpers that really pays dividends once you have it set up. The beauty is in the simplicity — you’re not modifying your saw, just adding capability that can be removed whenever you need the standard fence back. I particularly like how Rob oriented the plywood to use its natural bow as a clamping force rather than fighting against it.
The miter gauge channel is a smart addition that turns this from just a tall fence into a crosscut station. When you’re cutting tenons or dadoes on tall stock, having that extra support makes all the difference between a sketchy cut and a confident one. Just make sure your miter gauge is properly tuned before relying on it for precision work — a loose or worn gauge will telegraph any slop right into your cuts.
Safety-wise, this addresses one of the real problem areas with table saws. Tall, narrow stock wants to tip away from a low fence, and that’s when things can go sideways fast. The extra bearing surface keeps everything stable and predictable. For anyone considering building one, take your time with the fit — a sleeve that rocks or shifts defeats the whole purpose.
