I made a riving knife for a friend, and since I had extra material at hand, I made a couple of them if anyone is interested, I figured I’d post it here before it goes on eBay.

Made of 0.090” thick Aluminum these are an smooth fit into the saw and match the original tall riving knife thickness:

slightly below blade height to allow non-through cuts.

$25 includes shipping anywhere in the US.

PM me if interested.

The default riving knife rides above the blade? That seems like a poor design.

Keep in mind aluminum can flex. =)

Jon, riving knife refers to the concept of the splitter/knife traveling up and down with the saw blade (read does not stay at constant height like old-schools splitters do). there are high profile riving knives usually accompanied with a bolted on, or removable blade guard, and low profile knives for non-through cuts – this is what this one is.

As for Aluminum flexing – I am aware of it. this is 6061 aluminum, and at this size it’s pretty stiff. you could bend it if you REALLY wanted to, but installed in the saw, it is unlikely to be flexed away from the kerf line. I have been using mine for ~2 years now.

Looks like good work and a way to save some money versus purchasing the SC version from Sears Parts.
