Need more pictures and type of saw usually the support posts are adjustable to level and support the insert. It looks like you are missing a post or the bottom of the insert is hollowed out on that end.

All u hav to do is use a bit of tape around the edge so it fits the slot very tight. You can also use less pressure while cutting lol

Drill a countersunk hole through the insert.
Drill and make thread in the support and fix the insert with a screw.

Is your insert too high off the table?

If not, you could fasten a small extended piece of metal or wood to the bottom of the front (the end toward the back of the saw) that would slip under the table of the saw when inserted so it could not lift up.

When I make my zero-clearance inserts I use small brass screws on the underside where the tabs on my delta unisaw are placed to help level the insert.

Another option to the problem when you are cutting small pieces is to place a piece of 1/4 inch plywood over the saw blade and fix it in place with some double stick tap. Then you’ll have a zero clearance top that won’t tip.

Hope that helps.

In looking at your photos it looks like you have jack screws for each of the support pads (?). But the illustration of how the insert lifts shouldn’t happen with a workpiece. Your finger is pushing it down below the surface of the saw table….I would expect a workpiece to have to remain flat on the table and not be able to do that (even small ones). My (maybe incorrect) conclusion is that you are pushing the piece down as it exits the blade (?). I’m guessing you don’t have problems with larger pieces because you can’t apply pressure in a way that lifts the insert. thsi might be more likely if you use a push stick (instead of a push shoe). My only suggestion is to try and refine your technique; of course there’s a very good chance I’m completely wrong about all this.

Recess magnets into the bottom of the insert, at the point where it contacts the saw frame.

Get a tighter fit. Usually a “hook” tab is added to keep the back from rising up and being thrown by the blade, but you have the opposite problem.

Assuming you have the tab in the back, you could countersink a screw into the front, angled such that it catches just under the underside of the table. You would need to back the screw out to remove the insert, but it would solve your tipping problem.

A simple fix is attach a small tab of wood to the bottom of the cleat that will extend under the table a bit.

If its too loose, a screw in the edge front or back then adjust the tightness.

These are the posts that the plate rests on.

This is the original there is a small pin on the end that tip down and goes into nothing. It would stop the plate from tipping back.
As for my technique when using small stock I use this type of push stick.
Im liking the adding a piece on the rear, also on Kreg miter bars they have set screws in the sides to get a better fit might do that on one as well. Thanks for the info men.

Post #4. I was looking at your fingers and paid no attention to the saw blade, thus my suggestion is backwards to what I posted. Brad and RWE have nailed it for what I was trying to say.
