Topic tags/keywords: question tablesaw

I recently purhcased a Lee zero clearance insert for my older Craftsman table saw. I followed the directions exactly but it seems to be rubbing on my blade. I am not able to raise or lower the blade without it catching on the insert. I don’t think this is normal and was wondering if I should just massage the edges for a better clearance?

When you raise or lower the blade is the saw running?

Yes It sounds terrible when this I am doing this. When I have it set to my desired height and turn it on I can hear it rubbing on the insert. I was using a stock insert with a 3/4” opening and it was quiet as could be.

Try this. Move the rip fence so that it sits over the insert but not over the blade. Then lower the blade all of the way. With the saw running raise the blade to it’s full height. That should clean it up enough to keep it from rubbing.

When I cut the insert I placed a piece directly over the blade and started it under the isnert and raised it to its full height. I then did the same with a board covering the outer edge of the insert not covering the blade and it is still catching.

That’s normal. It’s a zero clearance insert, meaning no clearance between the blade and slot cut by it (this is what reduces/eliminates tearout). It will widen a bit over time.

Ok sounds good. I was so used to it being silent.

I can’t speak for any store bought zero clearance insert because I’ve never bought one. Every ZCI I have ever made has had no issues with rubbing on the blade after the initial cut. I have maybe 15+ ZCI’s for different kerf thicknesses, stacked dado’s etc. I’ve never had a rubbing on the blade problem. That doesn’t sound normal to me.

Is yours rubbing a consistent sound? could your arbor or blade be off a tiny bit?
