Made this zero clearance out of hardboard. Nothing new… Used the table saw, band saw and oscillating spindle sander. Works great.

Looks OK, but what holds it in? Don’t see any screw. Also, stock throatplate is about 1/2 thick. Wish you had posted a picture of the flip side.

When I get around to it I will post a picture of the bottom. Everything is attached from there and the hardboard was laminated up to about 1/2 like you say DYNO360. I know that MDF is the top choice for this, but I didn’t have any when I made it!

I have this same table saw and have made about 9 inserts for different blade configurations. I used 1/2 ply. In the future I will probably use mdf because a few of them have a minor amount of bow which can be a problem. I roughed it out on the band saw and then used carpet tape to stick the plywood to the stock insert. Then I used a flush trim bit at the router table. The last time I did it it took about 5 min to route 3 of them and they were all exactly the same as the stock insert. I use 4 small screws on the underside of the insert to level it to the height of the table. They are such a perfect fit that there is no need to screw them in. Now I only use the stock insert if I am cutting a bevel.

I made this same insert using MDF. I just traced the shape with the original insert and cut it with a scroll saw and sanded smooth. I put it in place, moved the fence over it to hold it down and while running the saw I raised the blade to make the slolt. Now, gravity holds it in place just fine.

Is this the R4512? I know when I made mine, I used some cheap 1/2” sandply from HD. The problem I had was that I has to router out the back where the insert actually sits on the protruding castings and those are only about 1/4” or less from the top. This made the insert fairly fragile and I need to make a new one. Did you have these problems?

hey darkone, I have the same saw. Trying to make a zero clearance insert is a real problem with that saw because of the leveling screws. Don’t know of a solution but maybe someone will come up with one.
