Skil Table Saw Rear Outfeed Support

Why I added an outfeed support to my jobsite saw

On a jobsite table saw, the workpiece almost always grows as soon as you hit the switch—2x lumber seems longer, sheet goods feel heavier, and keeping a cut tracking straight becomes more about control than horsepower. That’s why I added the Skil outfeed support to my SPT99 stand. It’s a simple accessory—just a rear support arm that extends the surface by up to 15 inches—but in daily use it does exactly what I need most: buy me a margin of control at the end of the cut.

Setup and compatibility

Installation was straightforward. The support mounts to the stand using aluminum brackets, and positioning is set by sliding and locking it with a hand knob. No special tools, no drilling. If you’re already running the SPT99 with its wheeled stand, this is essentially plug-and-play. I had it installed, aligned, and feeding stock in under 15 minutes.

Because the support references the stand rather than the table casting, setup is largely about getting the planes to agree. I set the saw on a flat patch of slab, attached the support, then ran a straightedge across the table and outfeed to check for co-planarity. A couple of minor adjustments later, the transition felt seamless—no lip to catch thin stock and nothing proud that would lift the trailing end of a panel.

A quick note on portability: adding the outfeed support didn’t meaningfully change how the stand folds, rolls, or stores. It’s light enough that I barely notice it during transport, and I leave it installed most of the time.

Build quality and design

The construction is a mix of hardened metal for the support assembly and aluminum for the mounting brackets. The result is lightweight but rigid enough for the kind of work this accessory is intended to handle—ripping 2x lumber, supporting cabinet parts, and catching the trailing edge of larger panels. There’s just enough adjustability to position it where you want it without introducing slop. The hand-tightening lock knob is fast and secure; I haven’t needed to put a wrench on anything.

All that said, aluminum threads are aluminum threads. They’re fine if you treat them like a clamping mechanism, not a vise. I make it a habit to snug the knob and stop—no gorilla torque—especially when the bracket is warm from the sun. Keep the threads clean and avoid cross-threading, and I’d expect long service life.

What the extra 15 inches actually does

Fifteen inches isn’t a replacement for a full outfeed table, nor does it pretend to be. It’s a safety and control buffer. With long stock, the moment when the workpiece clears the back of the blade is when things want to pivot, tip, or bind. That’s where this support helps most. It catches the material early enough to keep the cut line steady and keep the weight from levering the workpiece down off the table.

In practice:
- Ripping 8- to 10-foot 2x stock becomes much smoother. The trailing end clears the blade without a sudden drop, and I can keep my attention on the fence line rather than bracing for the last second.
- With cabinet-grade plywood, the support doesn’t turn a compact jobsite saw into a panel saw, but it makes controlled solo rips feasible when paired with sensible infeed and side support. The key is technique: start with a solid infeed plan and let the outfeed support finish the job instead of doing all the lifting.
- On narrow rips of thin material, the continuous plane avoids snipes or catches. I was able to rip down face-frame parts without them diving at the end of the cut.

The surface is slick and doesn’t mar the work. I still give it a light coat of paste wax whenever I wax the table; the transition feels glassy and predictable.

Adjusting and using the support

Day to day, the routine is quick: extend to where I want it, confirm the lock knob is snug, and check it’s still flush. Because it references the stand, any change in ground slope or stand leg position can nudge the geometry a hair. On stable floors it never drifts. On gravel or uneven subfloors, I give it a once-over during setup.

A few practical tips that have worked well:
- Set the support a whisper lower than the saw top—about the thickness of a playing card—to ensure the work doesn’t ride up at the tail.
- Resist the temptation to extend it further than you need. Shorter extension equals less flex and more stability.
- For sheet goods, add side support to keep the panel square to the fence, then let the outfeed support catch the trailing edge so you’re not overreaching.

Performance under load

I pushed it with some typical scenarios:
- 10' treated 2x8, ripping an edge straight: The support kept the tail from sagging, and feed pressure stayed consistent. No binding, no last-second wobble.
- 3/4" melamine, 24" x 48" panel: With a helper at infeed, the outfeed support was enough to finish the cut without chipping the exit corner. Solo, I’d still add a roller stand to the outfeed side for melamine simply because it’s heavy and slick.
- 1/4" plywood strips: The continuous support helped prevent chatter or drop-off at the end of the cut.

It’s worth emphasizing: this is an aid to safe, accurate cutting, not a substitute for good stock support planning. Used that way, it materially improves results.

Durability and maintenance

After weeks of site use, the support shows minimal cosmetic wear. The hardened metal components resist dings and the brackets stay tight. I do keep an eye on the aluminum threads. My routine:
- Blow out dust from the threads at the end of the day.
- Add a dab of dry lube to the screw every few weeks.
- Hand-tighten only—no tools.

Follow those basics and the hardware should last. If you’re working in freezing conditions, thermal contraction can make knobs feel looser; check them before the first cut.

Trade-offs and limitations

• Limited extension: 15 inches is enough to stabilize, not enough to fully support large panels. Plan for additional infeed/outfeed aids with sheet goods.
• Aluminum threads: perfectly serviceable, but be gentle. Over-tightening will shorten their life.
• Stand-dependent alignment: Because it mounts to the stand, alignment depends on how level and stable the stand is. Not a flaw—just the nature of jobsite setups.

None of these are deal-breakers; they’re simply realities of a compact, portable solution.

Who benefits most

• Remodelers and framers who routinely rip long 2x material on site.
• Cabinet installers using a jobsite saw for scribing fillers and trimming panels.
• Small-shop users who wheel a saw outside and need a compact outfeed solution that doesn’t eat space.

If you already own the SPT99 with the rolling stand, this accessory makes particular sense. It integrates cleanly, adds almost no weight, and improves control in the exact moment most cuts need it.

The bottom line

The Skil outfeed support is one of those modest accessories that quietly raises the floor of your saw’s performance. It won’t turn a portable saw into a shop cabinet saw, but it reliably tames the end of the cut, makes solo work more predictable, and packs away without fuss. Installation is easy, the construction is appropriately robust, and the adjustability is simple enough that it never becomes a chore.

Recommendation: I recommend this outfeed support for any SPT99 owner who regularly rips long boards or mid-size panels and wants a portable, no-hassle way to stabilize the tail of the cut. It’s not a replacement for a full outfeed table, and you’ll still want additional support for full sheets, but as a compact solution it’s effective, durable when treated sensibly, and worth adding to the stand.
