Ok Uni-users, here's a real dumb question. I bought a UHMW insert to
make a ZCI and it should be one of the easiest things to do. Right??
But when the blade is all the way down, it is only app 1/8 below the
table saw deck. The insert rocks on top of the blade, which won't let
me clamp it to the saw top. I have a 7 1/4" blade, but it's a narrow
kerf. Besides using a smaller dia blade to make room for the 10" blade,
how do you make your ZCI? TIA, Mark L.

You might try a 1/8th dado blade. Don't got no dado? I've roughed out the
underside of ZCI's to allow the needed clearance, so maybe use a router table
with a 1/4 inch plunge bit, stops,and a good workholding fixture. Take it to
your 1/8th limiting thickness where the blade will be aligned, then go to town.
I'm sure there'll be more ideas from the group.Tom
Someday, it'll all be over....

cut patialy through with a dado or a strait cut router bit. you can
also use a 7 1/4" full kerf blade to start the cut. 7 1/4 blades are
cheap enough. less than 5 dollars for a cheap one.

I wasn't thinking, I've got 2 dado blades.... Thanks

For a ZCI only the top of the slot need be the width of the blade. You can
hollow out the bottom however you like (switch blades, use a dado blade,
use a router, use a chisel). A stanley #271 may work well.

You can also use double sided tape to fasten the new insert to the top of
your standard insert to start the cut. Just be careful to properly line the
inserts up.
