Just a pointless question here but when I ran my blade up to make the slot on my ZCI the kerf of the blade still rides against the sides of the opening. I figured it would wear in over time but still doing this and it’s really annoying to hear it riding on the sides. Any fix for this? I figured I could try to file the sides a little but it’s a phenolic material so its super hard. It’s a Leecraft cr-3.

It will eventually wear a bit … I would just deal with the noise. Your ZCI is doing what it is intended to do.

just be careful that the blade doesn’t grab it and launch it at you like mine did

I had a leecraft that did that on a contractors saw I once had, I just filed it down a bit (the kerf near where the teeth contact the insert) the noise went away and it served me well for a long time. Not a lot with the file just enough to get rid of the racket, that leecraft stuff is very hard.

It’s normal and if you file it, it defeats the purpose of a zci.
Using hearing protection when sawing is the ideal solution.

@Shawn, how did it launch at you? The leecraft ones have a pin at the back to prevent that and shop made zci’s should have a nail or something like that installed to prevent what happened.

No pin on mine. Just the adjustment screws.

Have your say...
