Wanting to try the new breed of thin kerf blades for my Jet contractor tablesaw, however I already use a Freud 50 tooth combination blade. I would like to add a Freud 24 tooth thin kerf rip blade to my collection. If I switch back and forth from a full kerf to a thin kerf, do I have to re-adjust the curser on the tablesaw scale each time?
Thanks for any input you may have.

No, you do not. If you think about it, the side of the blade that faces the fence is always in the same position regardless of blade thickness. If you put the fence to the left of the blade, then you would have to readjust every time you switch blade thicknesses.

I see you point. Do most blades have the same offset between the blade body kerf and the tooth kerf? I was imagining the offset could be slightly different from one blade to another.
Thanks

Looking through the Freud catalog could seriously make your head spin.

In reality, you could have to change the cursor anytime you change blades. The carbide does not always register the same on the blade, even between full kerf blades. Of course it would probably be minimal then.

That said, if the blade mounts on the arbor with the nut toward the fence, it will make a big difference. If the nut is away from the fence, it might not matter—much. There is a difference between left and right tilt saws.

I hope this is not totally confusing. Bottom line—just check it on a scrap any time a blade is changed. I do.

Kent, I did not realize that left and right tilt saws had the nut in different places so thanks for correcting me there. I have a left tilt and my nut is away from the fence. The face of the blade should always be in the same place relative to the fence, as far as how much the teeth protrude I can’t say. I would assume that teeth would protrude the same amount on both thin and full kerf blades, and the difference is that the teeth and the plate of the blade are just wider both wider by the same amount on a full kerf.

My Jet is left-tilt, and the arbor nut is on the right side of the blade … side as the fence.

Thus, a different blade means a slight difference in the distance between the blade and the fence.

In my case, I adjust the scale every time I change the blade.

I don’t know if the factory splitters are as thin as a thin kerf blade. I have a home made splitter on my saw, 1/8” thick, and it binds a little when I use my thin kerf blade.

If the teeth are narrower on the thin kerf saw blade, and result in a smaller cut , then I should imagine that would definitely affect the cut hence the fence setting.The fence settings on my saw are uisually set by bringing the sawblade up till it meets the fence and then set the cursor at zero.Therefore a narrower blade will affect it IMHO I canot see how it wouldn’t.Alistair

My saw is like Gerry’s and I agree with his point. However, I don’t use the scale on the saw very much. I check distances from the blade to the fence with a metal ruler. For some reason, I just feel more comfortable that I have the distance right that way. I think this is a habit that dates back to the days when my only table saw was a ShopSmith with no index.

Yes if it’s a left tilt saw, but you can install a shim from a dado set against the flange to compensate for the difference in kerf width. Set the cursor at zero for the full kerf blade, then add the shim for the TK’s….or switch completely to TK’s.

Before I ditched the stock fence on my saw and installed my Shop Fox, I got into the habit of measuring with the ruler just as Rich does. I still do that … not that I don’t trust the scale on the fence. You know, measure twice, cut once!

The answer to your question is “yes”. If you have a left tilt saw and your rip fence is on the right side of the table.

Im with Rich et al,if you are looking for accuracy,use a good steel rule[or calipers].
