Bob, I don’t think you can.

Scott we’re thinking along the same lines it appears.

Hey Wayne is that a BORK?

As was stated early on , a riving knife can be used on non through cuts, which I knew. So? A non through cut is not going to pinch so the need for a riving knife or a splitter (if one could be used) is a moot point.

And having the riving knife closer to the blade I can see but with the splitter I have and the blade set to cut 3/4” stock the splitter is only 2-1/2” from blade exit which is pretty close to have the wood start to deform and close the gap. Never had that happen ever. With the blade at full height the distance decreases to 3/4”. And following the contour of the blade which of course then makes it closer to the blade I don’t see as any great advantage because again, I don’t believe the wood is going to pinch that quickly. Well at least from my experience.

The splitter I have on my Unisaw is a Delta part. Not widely known and not widely publicized. Knew about it when I got my Unisaw so tracked it down an bought one. Not only is it a sturdy splitter it’s a kickback preventer and it lowers when doing non through cuts. That is a big plus and was one of the reasons I wanted one. Having to unbolt and then bolt it back on can lead to, “oh, one quick cut I don’t need it…” thus not taking the time to bolt it back on.

I was wondering this because I read things like buy a new saw not an old one because you don’t get a riving knife and this and that and I just can’t see basing that on, to me, small items like this. Table saws have survived a long time without the latest whiz bang new gadgets.

Been aware of the BORK for a while now, (thanks Scott) but am having a hard time deciding whether a riving knife is so much better then the splitter pictured below which does tilt with the blade. Right now I’m leaning not. Well I guess a better way to put that would be not to use the word “better” but leaning towards not buying which is a 180 from a few months ago.
