Default Low profile riving knife.

I have a Jet Pr Shop 1 3/4hp table saw and I am looking for a low profile thin kerf riving knife. I have called Jet and they don't make one for my saw. They only have full kerf riving knives. Any suggestions?

Measure once cut twice and it's still to short.

I guess you could have one cut and finished at a machine shop. Use the thin one as a template. Might need to thin part of it down to fit the slot. Personally, I've switched to full kerf blades, they just work better without deflection.

The more I do, the less I accomplish.

Tom, I was using a full kerf also but I was getting a lot of burning while ripping. I then used my ripping blade and the burning was better but not gone. That is when I installed my thin kerf blade it stopped the burning. My saw is a 1 3/4HP and the thin kerf blade cuts easier but I agree a full kerf blade is better.

Make your own out of an old thin kerf blade or find a piece of metal the same thickness. Use the one you have for a pattern.

Just saying,

I do not have a riving knife for my old craftsman table saw. I use the micro gripper. The do keep the saw kerf from pinching the blade but does not prevent burning when cutting Walnut.

A riving knife is one of those things I'd like to have, but no one makes one for my old Delta. It originally had a splitter, so it isn't that old, but even that was lost before I got the saw. I thought about a micro splitter, but the blade comes very close to the end of the insert when it's all the way up so I don't think there's room for one.

The oem insert has another slot for the original splitter, you have lots of room there but more to the point with a thin kerf you will want a zero clearance insert anyway so there is loads of room for a slitter add-on.

I don't see any extra slot in the OEM insert. This saw is a 34-670, which isn't very big, the table is only 22" front to back.

Out of curiousity I just did a Google search to determine how old this saw might be. The oldest reference I saw is a manual from 1995. I really thought this saw was older than that.
