I have a DeWalt 7491 table saw. It has a nice stand, can be put away and out of sight, and it is powerful enough for my needs. It has a riving knife and a very easy means of installing and removing it. Id like to get a "standard" (?, 1/8") flat top grind Ridge Carbide blade (local manufacturer and Ive heard good things about them) blade.
The riving knife on my saw is sized for thin kerf blades. 0.94" or so, IIRC. I cannot seem to find a whole lot of info on riving knife application.
I can certainly understand that you wouldnt want the knife to be wider than the kerf of the blade. Then it would be its own source of binding. But what about thinner? Is there any intrinsic risk or problem with using a 3/32 riving knife for a 1/8" kerf blade? I cannot seem to find any wider ones from dewalt. Id imagine finding 1/8 stock and cutting a knife to the template would be very easy... But necessary????
Any thoughts or opinions?
Thanks!
