I’m posting this as a both a safety recommendation and a functional addition to some shops; though, the usefulness of the jig may be limited to sliding table saws (or cabinet saws with slider attachments) – I haven’t thought through how this would or could be adapted to a traditional cabinet saw.

I recently upgraded my main saw to a 9’ slider, and have been reviewing several youtube series by Steve Rowe and others, on useful jigs. This jig, call a Fritz & Franz, helps process small pieces on a machine built to handle sheet-goods. Oddly, I rarely work with sheet goods, and my interest in the slider focuses more on safety, precision, and flexibility.

Sliders have a processing blind-spot somewhere below 8”: the cross-cut fences (the ‘stops’ on them) register down to about 7.50”, and both ripping and crosscuting small pieces to the left of the blade can become poorly supported – you can still rip to the right of the blade, using the rip fence, but, you’re body is extended over the sliding table, overhead dust collector and 12” or 14” saw blade….
The F&F jig has a runner parallel to the blade seated in the miter slot (or sliding table slot) and two sections of plywood (sandwiched to 1.5”) to create a pinch point for either end of the work piece. Adhesive Tape Measures reference the distance to the blade, and these are seated in aluminum track positioned on the leading edges of the two plywood sections. Steve Rowe (Extremewoodworker) has an excellent youtube video on this,

Each plywood section is approximately 15” x 8” x 1.5”; Hartville Tool has the aluminum tracks and Measuring Tape; and the black handle is from J Winco. Assembly time is about two days: Steve could do it in about 4 hours, my guess.

By-the-way, I should have moved to a slider a decade or two ago. An absolute joy to use… but Lord, the cost will set you back…

If I can provide any additional information, please let me know.
Everyone, Do Take Care.

The fence on the slider’s table is slotted so that you can reposition it to be a stop. The outfeed end of the fence should end just before the blade. This way the cross cuts butt against the fence, but the workpiece doesn’t bind when the piece goes across the blade.

I see the value in this jig for a slider but I question why a machine that can cost upwards of $15K doesn’t either come with a manufacturer made version or have a one as an optional accessory.

It is a mystery… and one that I don’t know the answer to.

My guess is that these machines are intended for high-volume, commercial-industrial cabinet and panel-processing environments; and not for the DIY user – who needs small-piece processing. Also, while I can make a plywood version of the Fritz & Franz jig, any such add-on from Felder/SCM/Martin would be robust, precision-ground aluminum… and that would cut into the profit margin.

That said, for me, the saw is worth the money, as configured.

RUWI Maschinenbau makes a commercial version of the F&F jig; but seems to lack a measurement and stop block feature.

Have your say...
