I have attempted about 4 times to make some good quality zero clearance inserts for my R4512. They have always had something I didn’t like about them. Finally…I think I got it. Made from 5\8 mdf, the areas for the leveling pads are routed to 3\16. Aluminum tabs to prevent lift off, predrilled and CA glue with stainless pan head screw. Small washer for the magnetic catch. These things are finally perfect.

Good job. I like the way you handled the retention clip…just might steal that idea.

One tip I’d offer if you don’t already do this: MDF is not terribly resistant to the abrasion of the wood chips that the blade creates, and the inserts will eventually become larger around the blade. You can slow down this effect or stop it by dripping CA glue (super glue) around the slot. It strengthens the fibers… Great work!

I really like the extra steps you took, fine work!

Having a pile of spares is smart thinking.

For my Unisaw, I usually just use a flat piece of 1/2” BB plywood, but I’m considering placing several gussets on the underside to stiffen/flatten it up. Basically the same thing you did by recessing your tab surfaces.

These do look very consistent with each other and it looks like they are quality made. Nice work!

Nice job with these. A good reminder that I need to make a couple.

Tell us how it turned out. I did the same thing for mine and found that if you accidently pushed to hard on the insert the MDF bowed where it met the adjuster pads.

How did you cut/shape them? I just ordered my second for dado blades and I’d rather make my own but I don’t have a bandsaw currently and a jig saw doesn’t make very nice cuts.

My guess is CNC.. looks to perfect otherwise!

James- I really appreciate the CNC comment and I really wish I had one. Created a 2 piece pattern. And used a router with pattern bit. The trick was the time I took to build the pattern. I can make one of these from scratch in about 5 minutes now with the patterns. That was my goal.

Nicely done. I made some for my saw a few years back. Not quite as nice as yours, but they work good. I too used a router pattern bit. It works, but man I hate routing MDF. The dust is just horrible.

Very nice. I have always wanted to try making my own. Saved this post a long time ago thinking I would give it a go.

I had bought several lee craft plates, and have never got around to it. Getting close to needing more.
I will have to give it a go.

John, I have looked at that pic about a hundred times. I knew there had to be a way to produce easily
