Q: Can you add a riving knife to existing table saw? – R Meyer
Rob Johnstone: In most cases, I believe the answer is no. Many of us in the woodworking world have been asking the major tool makers to put riving knives on their saws for years. Not only did they avoid producing new saws with riving knives, but no aftermarket riving knives were produced as accessories. Now, as you may know, in order to get U.L. approval, all newly designed and made table saws must have a riving knife.
