After watching more videos about table saws I got excited and wanted to make a ZCI. When I looked at my saw the current insert gave way too much room. I had lost some wood down there on one occasion and was worried about kickback.
I took off the cheap flimsy plastic, that was starting to bow, only to find this:
Note: The "tab" on the right looks more recessed than it actually is
The place where the potential ZCI would rest is between 1/8th - 3/16ths of an inch from the table (both tabs are not equal distances from the table). That would mean for a very thin piece of the board at those locations. That would likely snap when it got some pressure. Also the side of the gap facing the blade (that you cant see in this picture) tapers at a 45 degree angle. I could see sawdust or, if nothing else, debris getting in there.
All the good ZCI's that I see are one unit and I don't see how I could do that with this setup.
Can I safely make a wooden ZCI for this table saw? Would I need to mill one from metal to get the same effect?
