Hello my fellow LJ’s I have a problem that I hope someone can help me with, I have a Ridgid R4512 Tablesaw with a throat plat that is only about 3mm thick and I desperately need to make some zero clearance plates, but because of how thin they need to be I don’t know what to do and or use that will be sturdy enough. I’m looking for any ideas, and I’m also hoping that maybe there is someone that may have had the same problem that may be able to help me out.
Thanks in advance.

Get some 1/8” Lexan( polycarbonate sheet) and trace your pattern and spot your holes and make your own. I have 2 of them for my Ryobi saw but they are 1/4” thick. 3mm seems pretty thin so you could use thicker material and just cut it to 3mm where it sits on the saw opening.

1/4” tempered hardboard also works. I am also adding a 1/2” BB ply backer plat to the under side.

I have a saw with a similar problem, I chose to purchase mine rather than make them.

I googled “ridgid r4512 zero clearance” and came up with several options for you saw around $28.

Cut a piece of pvc pipe lengthwise. Then heat it in the oven. It will soften so that you can press it flat between two boards. When it is cool, cut it to side. Look on Izzy Swan’s facebook page for full details.

I also used 1/4 tempered hardboard; easy to do using the throat plate as a template. Not meant to be long lasting but very easy to duplicate.

I have the same saw, and use the lee craft inserts. they work really well, and come in both zero clearance and for a dado. I think if you buy direct from lee craft you can get a deal on 3 or more. I bought 1 zero, and 2 dado, and am still using them today after two years.
Here is a link to a fellow lumberjocks project where he made his own insert. I saved it thinking I would make my own, but have not needed to.

quick update, I saw the amazon link wanting $75 for a lee craft plate. they are on crack. lol
here is a link to lee craft. $27.99 and free shipping if you spend $49.
You want an RG-5 for zero clearance, or a RG-6 for dado.

HDPE (High Density Polyethylene) makes very good zero clearance plate. The surface is lubricative and the material is rigid yet not brittle and it wont break. It will also last a long time. You can find the material on eBay.

Phenolic plates a little more expensive, but last a lifetime.

You can get this kit Rockler or from a place like this.

Find yourself an old road sign. They are about 1/8” thick, very strong and can be cut with carbide. They will last a long,long time. I make all kinds of plates and jigs with them.

I have made inserts out of ¾” plywood, and routed the undersides where it rests on the tabs, and where they would otherwise collide/interfere with the saw innards.

Have your say...
