Topic tags/keywords: tablesaw zero clearance insert hitachi

Hoping I can gain a little advice from the vast experience of some of the folks here:
I’d like to put a zero clearance insert into my Hitachi table saw but it doesn’t seem very well designed for it. The current insert is metal and very thin. If I were to make I new one, I can’t see anything to mount it to. The recessed lip that the current one sits on is maybe a 1/4 inch (probably less).
I thought maybe I could mount something to the blade shroud? Has anybody had any similar experiences.
In the pictures, the current insert is the red rectangle to the right.



Thanks for any help!

You might consider the metal thickness and see if 1 or 2 layers of formica glued together can be used. Drill the holes, mount , move your fence over the insert so it doesn’t move up and slowly raise what blade you use into the material. Viola! Insert.

i’ve done similar for an old Makita I used to have.

I have a similar situation and made mine from 2 pieces. The top is lexan or polycarbonite and the same thickness as the orignal metal part. Then I made the bottom part that goes into the hole from ply and contact cemented them together.

Yup. What Jagwah said….. If a 10” blade is too tall when you try n raise it up through your new insert, you could use a smaller diameter blade. Either use your fence to keep it down when raising the blade up (slowly), or just clamp a scap piece of 2×4 or anything across the table to hold the insert down while the blade is coming up through.

Just watch the blade flange while you raise the blade up. (don’t ask me how I know it). I built mine out of two pieces (look under my projects)

Maybe some 1/4 inch hardboard would work, otherwise wise you may have to plane down to thickness of your OEM.

” rout out the bottom side where the lips are to allow it to sit flush.” <<<<<< Good advice! When raising the running blade up though the new insert place the fence near the blade to hold the inseret down while cutting it from below.

Hi, I just made a zci for my cheapo ryobi TS routing out lips etc. on the back of the plate and tested until it fitted correctly.

Btw. I used 1/2” plywood and the left side of the plate ended up being too thin so the blade took off small chunks of the bottom layer on the ply (cheapo ply maybe?), I just looked around for the pieces I could find and glued them back in place, also gave the thin side a coat of glue and it made it stiffer.

In your TS it looks like left side spacing is really thin, if going with routing, you may want to use 3/4” or 1/2” x 2 glued up together for extra support, looks like there’s enough space below.

I believe if you call leecraft they may have one built for your table saw just recently.
