Topic tags/keywords: question tablesaw saw blade

Some of you may have seen my review of the “Freud LM75R010 10 Thin Kerf Glue Line Rip Blade a couple of days ago. Today, when I was putting the crosscut sled back on and lining it up ( I have a shopsmith, so the table moves too, hence the need to line up ) I noticed I was having a real hard time, so I got up close and personal, and eyeballed the blade in the kerf slot of the sled at the very end, turning the blade by hand, I noticed that the blade seemed to be oscillating from side to side in the slot. I figured it may be the blade, or it may be the shopsmith. Knowing that I had recently restored the shopsmith and it had less than 10 hours on all new bearings, I suspected the blade. I attached a dial indicator to a magnetic stand and attached the stand to the round tubes of the shopsmith. I zeroed the dial indicator, and rotated the blade by hand ( not touching the blade, using the rear output shaft for the jointer to rotate it. ) The dial indicator showed the Freud blade to be out a maximum of .017. I then put a 20 year old Makita blade on the shopsmith and conducted the same test. The makita blade was out a maximum of .006. Should I take this blade back, or is this acceptable deviation?

This is the magic bullet. No burning, No resistance smooth smooth smooth cutting!!!!

It apparently doesn’t make much difference in performance based on your comment.

Cheers,

It’s not normal.

Thin kerf blades bend easily. My Forrest bent, when they sharpened it, I had them straighten the plate.

Give Freud a call or send them an email. They are a very good company.

Brad, I agree to a point, but consider the fact that it’s always going to be cutting a wider kerf than it should.

Jeff, that is what I thought given the fact that this blade has only made 4 “clean up the edge” cuts in birch plywood since it was new, I don’t believe it bent on my table saw, I think it came to me that way.

It’s not normal as woodcheck said.

This is on my saw now, dial indicates about .003. Not sure about specs, but a few thou would be respectable. .017 is a bit much for me. If it’s new, take it back.

One of those stabilizer washers may help some. Freud SC-001 3-1/2-Inch Blade Stabilizer with 5/8-Inch Arbor for 7-Inch Saws or Larger

It should be better than that, but unless it’s notably effecting performance, I’m not sure I’d do anything about it.

.017” is way too much. The best blades like Tenyru and Everlast deviate about .002”. Does your saw use the 1-1/4” arbor?

Jerry,
I use Tenryus and see the same thing, but only on startup. When I reach saw/joint speed it seems to straighten out.

My saw uses an adapter to bring it down to a standard 5/8” arbor. As far as whether the blade straightens out at speed, I can’t think of a safe way to measure that, and I don’t think eyeballing it would do me any good since the blade would obviously appear to be straight at high rpms because of persistence of vision.

Okay, after doing a search on the phrase ” freud saw blade runout” I came across this article

http://www.woodtechtooling.com/FreudTooling/CommercialSawblades/ToolTips/FreudSawBladep11.html#Tips

Apparently the arbor flanges need to be at least 1/3 the diameter of the blade, so in my case, at least 3.3” I’ve never seen flanges that large, does anyone use flanges that large?

Jerry, the way I checked mine was to make a partial cut and measure the kerf against the blade’s width, by sliding it back on to the blade. Looked good to me. You might try that and use a dial caliper to verify. I’ve never gone to that extent.
edit: Freud makes a disk that is 3.5” in dia. Peachtree sells it.

you have to watch the stabilizer disk. The size may hit the insert when you take the blade all the way up. I do this when I resaw at the TS.
