I’ve seen a variety of sacrificial table saw fences for contractor table saws like my Bosch 4100. My main issue with all of them is that they either take too long to make or they cost too much. Or take up too much space on a saw that’s already limited in rip capacity.
An example of one that costs too much is any that involves Microjig Matchfit dovetail clamps. Today (March 18, 2025), they’re $45 for a pair. I love some of Microjig’s products, but $45 for a pair of clamps that’s just holding a sacrificial fence to my table saw fence is absurd. In general, my sacrificial fences stay in place until I need to replace them from wear or I need the special ones that are intentionally cut to accommodate blade-width edge cuts or using the dado set to cut rabbets. In other words, the clamping mechanism is semi-permanent; I am not loosening or tightening the clamps but once in a while. It’s also specific and fixed; it doesn’t need versatility. Finally, cutting dovetails takes way longer than other means. The cutting itself is quick, but I have to load the dovetail bit in the router, set its depth, clamp the work, etc.
An example of one that takes too long and uses too much space: parallel boards with space between for typical F or C clamps.
All that most of us want is a piece of scrap MDF held by fence clamps that only require one hole to be drilled per clamp. Fence clamps are less expensive than dovetail clamps; the Milescraft 7209 in a set of 4 is $23.99 today from Amazon. But there’s an even cheaper option if your fence isn’t too wide: Bessey TK-6 table clamps, which are $7.69 for a pair on Amazon as of right now. That’s what I’m using on my Bosch 4100. Drill a pair of 5/16″ holes in a piece of MDF and you’re ready to go.
