Default Tablesaw insert retainer

I have 3 tablesaws that I put to work at the same time, a Jet cabinet saw, a Ridgid TS3650 and a Craftsman hybrid saw, (I don't know the model number). The Craftsman and Ridgid both have screws holding the inserts in place, whereas the Jet doesn't. I always go through the exercise of removing and reinstalling the screws but always wonder how necessary they really are. Do any of you have this situation and what have you done?

My original Delta metal insert had a little nub on the end which seemed to be pretty effective at holding it in. But my homemade zero clearance plywood ones don't have anything and they've never shown any tendency to lift. When there's no material on top of them, they can't rise any higher than the blade guard anyway.
There's also no built in screw capability on the Delta contractor saw, so I'm guessing Delta was never confronted with the issue being a problem(?).
If one were worried, maybe a couple of rare earth magnets epoxied into the insert... (if the table is steel; not going to work well with Aluminum! )

I had a Craftsman with that set up Jack and I have a Unisaw. The Cman sits 1/8" into the table and is steel. The Uni's insert is 3/8" to 1/2" thick and is aluminum. The thicker plate is less likely to come out I think. I would a little concerned that the Cman insert could vibrate out and then catch the saw blade. Being that it is steel it wouldn't be good if that happened. Some rare earth magnets should be enough to keep that from happening if you can figure a way and the position on the saw to mount them. My top was aluminum which wouldn't help.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

My Rigid(4510 granite top) looks similar to your Craftsman inset. The original had 4 hold down screws. None of the zero clearance inserts(1/2" thick) that I have made have any screws in them and have never lifted. I made to have a very tight fit, so there is no movement thru vibration.

Hi Jack. I have a 12" Craftsman table saw I bought in the early 80"s and I have never used the hold down screw.

I have a 25 year old first model JET JTS-10 contractor saw that has no hold down screws in the original plate (it's cracked and only used as a template for making phenolic zero clearance replacements). That plate has never come loose after many thousands of cuts as there is minimal vibration, especially with the link belt. I agree that some rare earth magnets should work as those saws should all have a cast iron table but you might lose the leveling adjuster screws

Thanks guys, I hadn't considered magnets, only considered not using the screws. The Jet does fine without one so I could never figure out if it was a litigation issue or if there really was a concern for the plate lifting. Yes, all the tops are cast iron, only my jobsite saws have the aluminum, or nonferrous tops. I'm not always convinced that those tops are actually aluminum.

Delta cabinet saw and a Jet contractors saw and neither has screws. Like others I have made many wood and phenolic inserts and never had a problem with lifting. But I also have a small BT 3000 that has the VERY thin plate. I always screw it down for my safety. If the manufacturer made it that way they must have had a reason. I have made some wood inserts for this saw and added more bulk to the bottom. I don't use the screws for that insert and have had no problem with lifting.

My Unisaw insert came with a projecting pin at the back end of the insert. But it was cast aluminum, and dished slightly in the middle. I robbed the height adjusting screws out of it and used them in the 1/4 plywood insert I made using it as a pattern. I put a wood screw in the end of the plywood insert to take the place of the projecting pin and guard against the insert ever flipping up on the back end. I've never looked back.

We should be careful to get out of an experience only the wisdom that is in it and stop there lest we be like the cat that sits down on a hot stove lid. She will never sit down on a hot stove lid again and that is well but also she will never sit down on a cold one anymore. - Mark Twain

Jack I would not be to worry about leaving the screws out ( but if you are really worried about it just super glue a couple heavy nuts to the bottom for weight)
