Topic tags/keywords: jig tip tablesaw

I saw this on AmericanWoodworker. It’s a great idea.

Commercially made zero-clearance inserts cost about $20. I make my own for less than $3 from 3/8-in.-thick polyethylene cutting boards, which are flat and rigid. A 14-in. x 17-in. cutting board ($10 at a discount department store) yields four inserts. After rough-sawing the blank on my bandsaw, I attach the saw’s insert with double-faced tape. Then I rout the blank to final size using a flush-trim bit. I drill 11/64-in. pilot holes and install the adjustment screws, which are 3/8-in.-long #10-24 Allen-head set screws (about 40 cents each at a hardware store). Raising the blade through the polyethylene to cut the zero-clearance slot leaves plastic curls around the edge. They’re easily removed by filing or sanding.

Nice tip. I will have to keep this in mind the next time I replace my zero clearance plate.

The way I see it, with the cost this low, I could make a different insert for all the basic dado set ups (1/4, 3/8, 1/2, etc.) The dado insert that came with my Grizzly G0575 table saw is a “one size fits all” and there’s way to much space when using one of the smaller dado set ups.

Thanks for this, a table saw book I have suggests making them out of MDF but I like this idea too.

Yes it sounds like a great idea, but please note that I haven’t actually tried this yet. But I plan to sometime this weekend and I’ll let everyone know how it does. Heck, for the money, how could you go wrong?

I make mine exactly that way using luan plywood. Rout them out an put set screws in. It takes about 15 minutes to make one.

I’m with Chico, I use luan too, I usually make up about 6 at a time and throw them away as they wear out, I also make them for my bandsaw, and my router table. The router table you can make several sizes of bit hole sizes.

I’m lucky enough that I can make my ZCI’s out of 1/2” MDF.
